The NWP fields of T.H.U.V. of NMC's T63,T106 and ECMWF's numerical model were separtely interpoleted into 108 meteorological stations. The interpoleted results were used as predicting factors to establish predicting equations of max. and min. tempreture by means of PPM,MOS and KF filter methods. With the above predicted results,the second filter consensus forecast and perfect consensus forecast were made,and the Temperatute Forecasting System for Every County by the provincial meteorological observatory based on the NWP product was developed. The operational practics from June to November in 1997 proved that the system showed good predicting results.
