NOAA’s Climate Prediction Center, in partnership with the Indian Institute of Tropical Meteorology (IITM) and the Indian Meteorological Department (IMD), USAID, and the WMO, organized the Ninth International Training Workshop Climate Variability and Predictions in Pune, India, 13 – 21 April 2017. Workshop on Climate Variability and Predictions in Pune, India The training workshop led by Dr. Wassila Thiaw of CPC is part of a NOAA/CPC – USAID/OFDA series of annual global climate training workshops, a supplement to the CPC International Training Desks. Also serving as instructors during the workshop were Michelle L'Heureux, Muthuvel Chelliah, Jamal West, and Miliaritiana Robjhon.

In addition to providing professional development training for over 40 meteorologists from 15 countries of the Greater South Asia encompassing a region from Lebanon in the west to Indonesia in east, the workshop also provided an opportunity to develop a strategy for future training workshops. In particular, it has been suggested that the workshop agenda be mapped to the WMO Climate Information Services (CSIS), one of the pillars of the Global Framework on Climate Services to include: (1) Climate Data Management; (2) Climate Monitoring; (3) Subseasonal to seasonal forecasting; and (4) Downscaling of climate projections.

A courtesy visit with the Director General of the IMD was arranged. He expressed a strong interest in capacity development and praised NOAA support for improving climate modeling at IITM and IMD. Several side meetings with IITM scientists yielded opportunities for collaboration in the area of climate diagnostics with the CFST382 (Indian developed version of the CFS) and on heat health.

On Wednesday, June 14, 2017, NCEP Environmental Modeling Center upgraded the Air Quality Model (AQM) capability over CONUS. The AQM uses the Community Multi-scale Air Quality (CMAQ) modeling system to provide ozone and fine particulate matter air quality predictions.

This upgrade included a chemical transport model update to CMAQ V5.0.2; Improvements in ozone near coastal areasa National Emissions Inventory 2011 Point Source Emissions update to use 2017 projections; an update of the U.S. Forest Service BlueSky smoke emissions system to V3.5.1; an added 24-hour "analysis cycle" to include wildfire emissions when they were observed; an update of the bias correction technique for fine particulate matter (PM2.5) forecast guidance to use Kalman Filter Analogs; and an update of dust-related aerosol species at the CMAQ lateral boundaries to use the NGAC V2 forecasts. These changes improve raw and bias-corrected PM2.5 products (especially near wild fires), and improve summertime surface ozone predictions, especially in coastal areas. This upgrade is CONUS only, and does not include Alaska and Hawaii.

The current Hurricane Coordination Hotline (HCH) is a dedicated telephone line connecting National Weather Service (NWS) national centers and coastal forecast offices, along with the U.S. Navy Atlantic Meteorology and Oceanography Center at Norfolk, VA, the U.S. Navy facility at Jacksonville, FL, and NASA at Cape Canaveral, FL. The hotline is primarily used to coordinate forecasts and warnings of tropical cyclones in the Atlantic basin.

When the U.S. coast is threatened, the affected coastal NWS weather forecast offices, the regional offices, and the Storm Prediction Center are also included in the calls. As part of the forecast and warning process, the National Hurricane Center (NHC) initiates a conference call on the HCH every six hours during all tropical cyclones for the purpose of coordinating the official forecast to be released. The hotline coordination call is key as it is the final coordination step in the six-hour cycle of issuing forecasts. The new hurricane hotline video capabilitiesThe new hurricane hotline video capabilities are demonstrated during a hotline call with multiple centers and weather forecasting offices on the first day of the 2017 hurricane season.

During the 2015 Hurricane Season, the NWS experienced many outages of the Hurricane Coordination Hotline which caused issues in NHC releasing quality forecasts when tropical cyclones were present. The analog technology used to support the hotline is antiquated and only supports voice conversations, so graphics that should be available to facilitate coordination are not supported. Since the current hotline is outdated, the lines are impacted by static, making it difficult to hear the calls, and AT&T has extended response times to address issues, which does not meet NWS expectations and requirements.

In fiscal year 2016, requirements for a replacement system were identified by NCEP Central Operations (NCO) which would create a replacement collaboration tool with the capabilities to allow both voice and video conferencing calls with the ability to add additional sites as needed. A fully digital Cisco Unified Communications solution was selected to replace the current hotline and a Cisco Call Manager and new DX-80 Desktop Video Teleconferencing units were installed prior to the beginning of the 2017 hurricane season so that the new hotline system could run in parallel with the old hotline during the current hurricane season. Since the new hotline does not require analog phone lines, anyone with a teleconference interface accessible across the NWS network, and even the Internet, can join in on the calls. The video capabilities of the new hotline allow for coordination on graphics, including track model forecasts, probability distributions, and warning areas, due to be release in the six-hour cycle of issuing forecasts.

1) Storm Surge Watch/Warning becomes operational
Beginning with the 2017 hurricane season, the National Weather Service (NWS) will issue storm surge watches and warnings to highlight areas along the Gulf and Atlantic coasts of the continental United States that have a significant risk of life-threatening inundation from a tropical cyclone, subtropical cyclone, post-tropical cyclone, or a potential tropical cyclone.Hurricane Matthew Sotrm Surge Warning

Storm surge is often the greatest threat to life and property from a tropical cyclone, and it doesn’t always occur at the same times or locations as a storm’s hazardous winds. In addition, while in most cases coastal residents can remain in their homes (or in a secure structure nearby) and be safe from a tropical cyclone’s winds, evacuations are generally needed to keep people safe from storm surge. Having separate warnings for these two hazards will save lives by better identifying the specific tropical cyclone hazards communities face, and by enhancing public response to instructions from local officials.

The storm surge watch/warning areas are determined by a collaborative process between the NHC and local NWS Weather Forecast Offices (WFOs). The primary objective guidance will be P-Surge, an ensemble-based probabilistic system driven by the SLOSH model, the latest NHC official tropical cyclone forecast, and the typical historical errors associated with NHC forecasts. Forecaster confidence, continuity from advisory to advisory, and other subjective factors will also help determine the areas placed under a watch or warning.

The definitions for the new storm surge watch and warning are:

Storm Surge Watch: The possibility of life-threatening inundation from rising water moving inland from the shoreline somewhere within the specified area, generally within 48 hours, in association with an ongoing or potential tropical cyclone, a subtropical cyclone, or a post-tropical cyclone. The watch may be issued earlier when other conditions, such as the onset of tropical storm-force winds, are expected to limit the time available to take protective actions for surge (e.g., evacuations). The watch may also be issued for locations not expected to receive life-threatening inundation, but which could potentially be isolated by inundation in adjacent areas.

Storm Surge Warning: The danger of life-threatening inundation from rising water moving inland from the shoreline somewhere within the specified area, generally within 36 hours, in association with an ongoing or potential tropical cyclone, a subtropical cyclone, or a post-tropical cyclone. The warning may be issued earlier when other conditions, such as the onset of tropical storm-force winds, are expected to limit the time available to take protective actions for surge (e.g., evacuations). The warning may also be issued for locations not expected to receive life-threatening inundation, but which could potentially be isolated by inundation in adjacent areas.

The Potential Storm Surge Flooding Map, which became operational in 2016, will continue to be issued in 2017. This product provides quantitative information on the storm surge hazard associated with tropical cyclones, highlighting geographical areas where inundation from storm surge could occur and the height above ground that the water could reach. The map depicts inundation levels that have a 10-percent chance of being exceeded, which can be thought of as representing a reasonable worst-case scenario for any individual location. The first map will usually be issued at the same time as the initial hurricane or storm surge watch or warning, but can be issued at other times as appropriate, including for some tropical storm watches or warnings. The map is based on the latest forecast track and intensity for the tropical cyclone, and takes in to account likely forecast errors. The map is subject to change every six hours in association with each new NHC full advisory package, and is generally available about 60 to 90 minutes following the advisory release.

2) Issuance of Watches, Warnings, and Advisories for Potential Tropical Cyclones

In 2017, NHC will have the option to issue advisories, watches, and warnings for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 48 hours. Under previous longstanding NWS policy, it has not been permitted to issue a hurricane or tropical storm watch or warning until after a tropical cyclone had formed. Advances in forecasting over the past decade or so, however, now allow the confident prediction of tropical cyclone impacts while these systems are still in the developmental stage. For these land-threatening “potential tropical cyclones”, NHC will now issue the full suite of text, graphical, and watch/warning products that previously has only been issued for ongoing tropical cyclones.

Potential tropical cyclones will share the naming conventions currently in place for tropical and subtropical depressions, with depressions and potential tropical cyclones being numbered from a single list (e.g., “One”, “Two”, “Three”, …, “Twenty-Three”, etc.). The assigned number will always match the total number of systems (tropical cyclones, subtropical cyclones, or potential tropical cyclones) that have occurred within that basin during the season. For example, if three systems requiring advisories have already formed within a basin in a given year, the next land-threatening disturbance would be designated “Potential Tropical Cyclone Four”. If a potential tropical cyclone becomes a tropical depression, its numerical designation remains the same (i.e., Potential Tropical Cyclone Four becomes Tropical Depression Four).

Potential tropical cyclone advisory packages (i.e., the Public Advisory, Forecast/Advisory, Discussion, Wind Speed Probability Product, etc., along with all the standard tropical cyclone graphics) will be issued at the standard advisory times of 5 AM, 11 AM, 5 PM, and 11 PM EDT. Three-hourly Intermediate public advisories will be issued for potential tropical cyclones at 2 AM, 8 AM, 2 PM, and 8 PM EDT when watches or warnings are in effect. The product suite will include a five-day track and intensity forecast just as is done for ongoing tropical cyclones. In addition, the Potential Storm Surge Flooding Map and Storm Surge Watch/Warning graphic would be issued for these systems when appropriate.

Advisory packages on potential tropical cyclones will be issued until watches or warnings are discontinued or until the threat of tropical-storm-force winds for land area sufficiently diminishes, at which point advisories would be discontinued. However, if it seems likely that new watches or warnings would be necessary within a short period of time (say 6-12 hours), then advisories could continue for a short time in the interest of service continuity. Once a system becomes a tropical cyclone, the normal rules for discontinuing advisories will apply. Potential tropical cyclone advisories will not be issued for systems that pose a threat only to marine areas.

Because NHC will be issuing its normal graphical products depicting the five-day forecast track and uncertainty cone for potential tropical cyclones, to avoid potential confusion the Graphical Tropical Weather Outlook will no longer display a formation area for these systems.

3) Experimental Time of Arrival of Tropical-Storm-Force Winds Graphic

The arrival of sustained tropical-storm-force winds is a critical planning threshold for coastal communities, as many preparedness activities become difficult or dangerous once winds reach tropical storm force. Frequently, this timing is estimated using the deterministic NHC track, intensity, and wind-field (size) forecasts, but such an approach doesn’t account for forecast uncertainty, and communities can be caught off guard if a storm speeds up or grows in size beyond what was forecast. To provide guidance on when users should consider having their preparations completed before a storm, NHC will begin issuing in 2017 experimental Time of Arrival of Tropical-Storm-Force Winds graphics. These graphics will be driven by the same Monte Carlo wind speed probability model that is currently used to determine the risk of tropical-storm- and hurricane-force winds at individual locations – a model in which 1000 plausible scenarios are constructed using the official NHC tropical cyclone forecast and its historical errors.

The primary graphic displays the “earliest reasonable” arrival time, identifying the time window that users at individual locations can safely assume will be free from tropical-storm-force winds. Specifically, this is the time that has no more than a 1-in-10 (10%) chance of seeing the onset of sustained tropical-storm-force winds – the period during which preparations should ideally be completed for those with a low tolerance for risk. A second graphic will show the “most likely” arrival time – that is, the time before or after which the onset of tropical-storm-force winds is equally likely. This would be more appropriate for users who are willing to risk not having completed their preparations before the storm arrives. Users will also be able to overlay the standard wind speed probabilities, providing a single combined depiction of the likelihood of tropical-storm-force winds at individual locations, along with their possible or likely arrival times.

The Hazardous Weather Testbed (HWT) Spring Forecasting Experiment (SFE), organized by the Storm Prediction Center and National Severe Storms Laboratory, was conducted in May for five weeks. Over 70 forecasters, researchers, model developers, university faculty, and graduate students from around the world participated in the testing and evaluation of emerging scientific concepts and technologies designed to improve the prediction of hazardous convective weather.Storm Prediction Center and National Severe Storms Laboratory

During the 2017 HWT SFE, considerable focus was placed on the extraction and creation of probabilistic guidance from convection-allowing ensemble prediction systems, and the use of this information by forecast teams to create experimental severe weather hazard outlooks valid over shorter periods (i.e., 4-hr periods) than current SPC operational products. These activities are foundational to the emerging FACETs vision and are linked with initial Warn on Forecast efforts.

For the second year, the community-leveraged unified ensemble (CLUE) was the primary focus of the coordinated convection-allowing modeling (CAM) effort during the 2017 SFE, where NSSL, NOAA Global Systems Division (GSD), NOAA Environmental Modeling Center (EMC), NOAA Geophysical Fluid Dynamics Laboratory (GFDL),Storm Prediction Center and National Severe Storms Laboratory National Center for Atmospheric Research (NCAR), Developmental Testbed Center (DTC), and the University of Oklahoma Center for Analysis and Prediction of Storms (CAPS) worked closely together on model specifications and configurations for CAM simulations provided during the 2017 SFE. The resultant coordinated experiments were designed to help inform CAM ensemble configuration (e.g., model core, physics, data assimilation, etc.) for future operational versions of the high resolution ensemble forecast (HREF) system in the NWS. Additionally, convection-allowing deterministic runs of FV3 from GFDL and CAPS were examined for the first time in real-time during the 2017 HWT SFE.

The Space Weather Workshop (SWW) annually brings government agencies, academia, and industry together in the Nation’s leading conference on all things space weather. First held in 1990, this year’s conference expanded its space. The University Corporation for Atmospheric Research (UCAR) Community Programs, Cooperative Programs for the Advancement of Earth System Science, hosted this year’s event, attended by 265 people from nineteen countries and featuring sixty oral presentations and eighty-eight poster presentations.

Research to Operations/Operations to Research was a major focus this year with a number of sub-themes also covered. In addition to recent scientific advances in specifying and predicting space environmental conditions, the workshop highlighted space weather impacts in several areas, including ionospheric disturbances, satellite drag, auroral currents, geomagnetic storms and their solar drivers, radiation belts, and solar energetic particles.  Representatives from industries impacted by space weather, including those from electric power, commercial airlines, satellite operations, and navigation/communication, offered their perspectives.

The SWW included tours of SWPC, the 11th Annual NOAA/SWPC - Commercial Space Weather Interest Group (CSWIG)/American Commercial Space Weather Association (ACSWA) Summit Meeting, and Banquet Dinner. The tour included an overview of the Space Weather Forecast Office, allowing attendees a glimpse into SWPC’s capabilities to produce forecasts and warnings of space weather events. The Summit Meeting focused on the relationship between government and commercial space providers. Dr. Alan Stern, Associate Vice President and Special Assistant to the President, Southwest Research Institute, highlighted the Banquet Dinner with his words on “The Exploration of Pluto by New Horizons”.

In an effort to support improvements in the Weather Prediction Center's (WPC) precipitation forecasts, the Hydrometeorology Testbed at WPC (HMT-WPC) partnered with other NWS meteorologists, hydrologists, weather researchers, and developers, to conduct the 2017 Flash Flood and Intense Rainfall Experiment (FFaIR). This year's experiment again benefited from the engagement of a diversity of partners including the National Water Center, Environmental Modeling Center, and the UK Met Office. Participants evaluated new tools and datasets with a focus on heavy precipitation and flood forecasting. Results from the experiment will help inform how best to apply new tools and datasets to operations.

The 2017 experiment ran for four weeks beginning June 19. It focused on the use of high resolution guidance to improve both short range (6-12 hours) and longer range (48-72 hours) flash flood forecasts. To simulate the flow of information from a national center (e.g. WPC) to local forecast offices, this year’s daily experiment briefings were open to the Science and Operations Officer community in real time through a hosted daily teleconference. This year’s experiment also emphasized rapid integration of the latest observational and model guidance into the decision making process by challenging participants to simulate the collaboration that occurs between national centers and local forecast offices ahead of and during flash flood events.

On June 5th, the Weather Prediction Center contracted with the Eastern Research Group, Inc. (ERG) to host an interactive workshop with approximately 40 stakeholders. Of the 40 participants, about half were internal to the NWS and the other half were comprised of media and other Federal agencies. This was an opportunity for WPC to receive constructive feedback on how customers and partners use and interact with national center products, as well as an opportunity for those stakeholders to provide input on WPC’s future initiatives. WPC is especially interested in core partner decision-making and how the national center services can be improved to further enhance these important relationships.

Several themes emerged during the course of the workshop:

  • Organizational clarity and audience definition: Stakeholders want WPC to clarify its mission and define and engage its customer base, which currently consists of both experts and non-experts.
  • Improved products and website: Stakeholders desire more intuitive graphics that are easy to understand and easy to find on NWS websites. They also want to see more consistency in the look and feel of graphics across the NWS, as well as less technical language.
  • Improved impact-based decision support services (IDSS): Stakeholders want the value-added interpretation of complex forecast information and commented favorably on the expertise of WPC forecasters to deliver this kind of interpretation.
  • Data needs: Stakeholders want WPC to provide products in "GIS-friendly" formats along with open data, and good metadata, with units clearly and consistently expressed.
  • Internal NWS coordination, collaboration, and communication: Stakeholders embraced a "one event, one forecast" concept and want to see more collaboration between National Centers as well as between the National Centers for Environmental Prediction (NCEP) and weather forecast offices (WFOs).
