definition: Short Title: THORPEX-IPY Project URL: http://www.ipy-thorpex.no/ Proposal URL: http://classic.ipy.org/development/eoi/proposal-details.php?id=121 The WMO/WWRP's THORPEX Global Research Programme involves nations from North America, Europe, Asia, Africa and the Southern Hemisphere. THORPEX intends to conduct research that will accelerate improvements in the prediction and understanding of high-impact weather on the 1 to 14-day time-scale for the benefit of society, the environment and the economy. The aims of this cluster proposal are to improve numerical weather prediction model systems and climate models by utilizing remotely sensed and in situ observations taken during the IPY and to study and advance our knowledge of meteorological, surface and ocean phenomena typical for the region. The investigations will also improve our understanding and modelling of polar-global interactions. The scope ranges from high-resolution numerical weather prediction to climate and regional ocean modelling. The motivation comes from several applications: 1) Regional weather forecasting: In polar areas there are strong needs for accurate weather forecasts. Further model-based ocean, ice and wave forecasting need accurate forcing fields. 2) Medium range (global) weather forecasting: Improved model quality in polar areas influences forecasts at mid and high latitudes. 3) Climate studies. The project has four objectives: The first is on forecasting and to what degree an improved use of satellite data and an optimized observational network, including targeted observations, will improve forecasts of high impact weather events (IPY project numbers 294; 394; 638; 600; 798; 811; 113; 146; 206, 410, 92, 888, contribution related to meteorology). These studies will not be limited to forecasting conditions over the poles, but will also address polar-global interactions. These investigations will provide insight into the design of the global observing system and into the potential impact of any I…
