Programme
WORLD WEATHER RESEARCH PROGRAMME
Develops improved and cost effective weather forecasting techniques, with emphasis on high impact weather and promotes
their application among Member States.
SYNOPTIC PREDICTABILITIES (THORPEX)
A 10-year international research and development programme to accelerate improvements in the accuracy of one-day to two-week
high impact weather forecasts for the benefit of society, the economy and the environment.
MESOSCALE WEATHER FORECASTING RESEARCH
Promotes, organizes and/or endorses end-to-end weather research and development projects (RDPs) including
understanding of weather processes, improving forecasting techniques and the utility of forecast information with an emphasis
on high-impact weather.
TROPICAL METEOROLOGY RESEARCH
Promotes, Identifies and supports research initiatives relevant to the high-impact weather forecast requirements of NMHSs in
tropical and monsoon regions, and thus contribute to social and economic benefits by preventing or mitigating disasters via
imporved forecasts of tropical cyclones and anomalous monsoon rainfall.
NOWCASTING
Promotes and aids the implementation of nowcasting in the WWRP framework and within NMSs and among their end-users, including the potential use of numerical modelling and
assimilation of very high resolution data.
VERIFICATION
Facilitates the development and application of improved diagnostic verification methods to assess and enable
improvement of the quality of weather forecasts, including forecasts from numerical weather and climate models.
SOCIETAL AND ECONOMIC APPLICATIONS
Advances the science of the social and economic application of weather-related information and services and reviews and assists
in the development and promotion of societal and economic-related demonstration projects.

forecast requirements of NMHSs in tropical and monsoon regions, and thus contribute to social and

WWRP-TMR
1. Tropical Cyclone Panel:– Expert Team on Observation, Processes and
Prediction– Expert Team on Landfall Processes– Expert Team on Climate Impacts on TCs– Limited Area NWP
2. Monsoon Panel:– Expert Team on Severe Monsoon Weather– Expert Team on Climate Impacts on Monsoon
Weather– Monsoon Activity Centers
Monsoon Panel Strategy
• Climate Scales: Global change, Decadal, Interannual, Seasonal, down to intraseasonal– Cooperate with and support WCRP monsoon activities– Cooperate with regional and international programs
(e.g., APEC Climate Center)– Research on Climate Impacts on local weather
• Weather Scales: Convection, Meso-, Synoptic, up to Intraseasonal– Regional and Local phenomena, effects of terrain– Top priority: Torrential rainfall, flooding– Joint efforts with TMRP/TC component
Activities
• Scientific and Training Workshops– Review state of the art, current issues and future directions– Facilitate researchers - forecasters interactions – Relating research results to forecasters on an ongoing basis– Update WMO Report on Monsoon for Member NMHSs.
• WMO Monsoon Activity Centres– New Delhi (IMD: South Asia)– Kuala Lumpur (MMS: Southeast Asia)– Beijing (CMA, East Asia)
• Encourage, endorse and support weather scale monsoon research through regional and international cooperation
Research Projects• Encourage, endorse and support weather scale monsoon
research through regional and international cooperation– Examples
• SCHeREX Southern China Heavy Rainfall EXperiment (MAPHRISC: CAMS/CMA, IAP/CAS)
• SoWMEX Southwest Monsoon EXperiment (CWB/NTU)
• TiMREX Terrain-induced Monsoon Rainfall EXperiment (NSF/NCAR)
• PHONE06-15 Pukyong Natl U - HyARC, Nagoya U Observation Network over East China Sea
– Relevant WWRP-TMR/TC Project• TCS08 Tropical Cyclone Structure 08 (ONR/NRL/NPS)

Network over East China Sea
• Nine-year observational project starting 2006 over southern part of South Korea, East China Sea, and Okinawa
• Purposes:– Formation mechanisms of precipitation systems associated
with the Meiyu/Baiu/Changma front and typhoons over ECS. – Research in short-term forecasting of heavy rainfalls (QPE
and QPF)• Observations and Modeling:
– Ground, sounding and satellite data– Doppler radars– Cloud resolving model
• Linkage– Coordination with SoWMEX/TiMREX being planned.
