Complex forecast of surface meteorological parameters

The statistical scheme using the results of the best foreign global schemes and the COSMO-RU7 regional scheme is proposed for forecasting surface temperature for five days and the amount of precipitation for three days. Presented are the estimates of prognostic values of the surface air temperature and amount of precipitation for the period of July 2010–June 2013. The joint statistical taking account of different types of systematic errors in the complex forecasting scheme enables excelling all initial schemes in quality. A scheme of the complex forecast is operationally used and its results are daily updated on the website of the Hydrometcenter of Russia at 09:15. The forecasts of extreme temperature, dew-point temperature, and wind speed near the surface are also presented on the website.
