• In 2009, the tyhoon Ketsana made the worst damage in Southeaset Asia. • After passing Phiippines, it hit Viet Nam, Laos, Cambodia and Tailand.• The total loss of lives are about 700 and the estimated damage reachs
over about $700 million to $1.0 billion USD.

14th Session of RA-II• 4.1.2 The Association noted that the Severe Weather
Forecasting Demonstration Project (SWFDP) has achieved significant results and benefits relative to the GDPFS and PWS programmes in its first regional project in Africa, and requested the Working Group on Disaster Risk Reduction and Service Delivery [ref. XIV-RA II/Doc. 5.1] to consider developing a SWFDP RA II project as a method for enhancing the GDPFS and PWS and contributing to disaster risk reduction goals in developing countries, for example, those in Southeast Asia that have recently experienced disasters.
Workshop on SWFDP DevelopmentFor Southeast Asia
• Workshop on SWFDP Development For Southeast Asia (Ha Noi, Viet Nam, 2-5 Februrary, 2010)
– Chair : Edwin S. T. Lai (HKO) • Coordinator of Working Group on Disaster Risk Reduction and
Service Delivery in RA-II
• CBS endorsement– 3rd meeting of Steering Group of SWFDP (Feb.2010, Geneva)
• recognized this arising sub-project and gave the highest priority to this sub-project with other 2 sub-projects.
– CBS Extraordinary Session (2010) (Namibia; Nov. 2010)
Target Severe Weather EventsThe following events are focused in order of decreasing
priority and associated hazards such as flooding, landslides, high waves and swell:
• tropical cyclone (both from the South China Sea and from the Bay of Bengal) track, intensity, structure changes and landfall process (wind and gust, rainfall and storm surge);
• heavy rain triggered by tropical cyclones, SW and NE monsoon, troughs and ITCZ migration, and orography;
• thunderstorms and hail associated with severe convection;• cold conditions and frost;• extreme hot and dry conditions associated with föhn effect.

Synergy with Other Regional Activities
There are some on-going and planned projects related to NWP system and products.
• RA II Pilot Project on City-specific NWP forecasts
• JMA Pilot Project on EPS Products (EPS-WEB)
RA II Pilot Project on City-specific NWP forecasts
• 13th Session of RA II - to enable developing countries of RA II access NWP products;
• By the beginning of 2009, 18 countries had joined the Project; and,
• Hong Kong, China; Japan and the Republic of Korea provided forecast time series products for over 160 cities to 13 countries.

The products in JMA EPS-WEB are recommended by Manual on the GDPFS (WMO No.485).
• In addition to the web-site for public users, JMA provides a web-site for meteorologists and forecasters in foreign countries.
• The special forecast products derived from EPS are disseminated on the website, “JMA EPS-WEB”, supporting the activity of National Meteorological and Hydrological Services (NMHSs) in Asia.
• The data in this website is available for operational weather forecasting in your countries.

Synergy with TIGGE/GIFS in RA II
• CMA– Archive Centre of the THORPEX/TIGGE project– Store EPS products from 10 NWP centres every
day.
• MRI– North Western Pacific Tropical Cyclone (TC)
Ensemble Forecast (NWP-TCTEF) Project
• A WWRP-RDP project “North Western Pacific Tropical Cyclone (TC) Ensemble Forecast (NWP-TCTEF) Project” intends to build on the TIGGE concept and take advantage of the TIGGE CXML data provided by multiple organizations for improving TC track forecast skill over the North western Pacific, starting from 2009, as a five-year project.
• The objectives of the NWP-TCTEF Project are:- to explore and develop effective ways of obtaining and utilizing the track forecast
data from TIGGE data providers to improve medium range forecast of TC track forecast
- to develop software for a real time multi-model tropical cyclone forecasting system from data transfer to verification
- to evaluate the utility of multi-model forecasts of tropical cyclones track predictions and provide recommendations on future multi-model ensemble systems and on future GIFS-RDPs
