A MOS Prediction System of Precipitation, Surface Air Temperature and Wind in Hubei Province
Based on the explanation and application of T213L31 numerical forecast model pro ducts, an operational MOS prediction system and a set of realtime statistical prediction equations are established for stations of Hubei province. The system firstly adopted Kalman Filter and AnalogueKalman Filter, and the equations sel ected several linear predictors that are relative to the model outputs, such as precipitation, surface air temperature and wind fields. This MOS system can for ecast above meteorological elements quantitatively in the form of fixed point (e very county), fixed time (every six hours). The experiments show that the MOS sy stem has good stability and excellent forecast scores in the testing period in J uneAugust from 2005 to 2006.
