The “WMO Typhoon Landfall Forecast Demonstration Project (TLFDP)” was started in May 2010 in conjunction with the start of the Shanghai World Expo 2010. The project was successful in terms of assisting the local forecasters in providing efficient tropical cyclone (TC) forecast service for World Expo 2010, demonstrating the performance of the most up-to-date techniques in TC forecasting, and enhancing the ability of forecasters to effectively use products of the most advanced TC forecasting techniques in the world. It completed its first phase in December 2012 and second phase in December 2015. The third phase (TLFDP-III) was started in 2016.
During its first (2010-2012) and second (2013-2015) phases, TLFDP collected real-time TC forecast products from 15 Typhoon Forecast Product Providers (TFPPs), including deterministic track and intensity forecasts, ensemble track and intensity forecasts, deterministic wind radii forecasts, wind probability forecasts, and gridded model outputs. The products were disseminated through the project’s website and the operational website of the Shanghai Typhoon Warning Center.
TLFDP has made significant progress in TC forecast verification, including setting up the tools for both real-time and post-season TC forecast verification, developing and integrating several new verification techniques, carrying out a survey on the operational status of TC forecast verification in the western North Pacific region, and contributing to the WMO document “Verification of tropical cyclone forecasts”. The post-season forecast verification was reported to the Session of the UNESCAP/WMO Typhoon Committee since 2013. New consensus methods for TC track and intensity forecast were also proposed either based on Ensemble Prediction Systems (EPSs) products or multiple deterministic NWP model products.
Two training workshops on TC forecasting were held by TLFDP in Shanghai, China, in May 2010 and June 2012, respectively, and seven research fellowship projects were implemented as jointly supported by the UNESCAP/WMO Typhoon Committee, Shanghai Typhoon Institute and Hong Kong Observatory.
In its third phase (TLFDP-III, 2016-2018), the project will continue its effort on demonstration and evaluation of the newly developed forecasting techniques for TC, and developing and documenting advanced guidance for the verification of TC forecasts, with special attention to TC intensity and precipitation.
