Abstract:: By using the precipitation data from 2011 to 2014 and the daily temperature data in 2015 in 80 meteorological stations in Anhui Province, combining with the DEM data of 30 m, we selected inverse distance weighting (IDW), radial basis function (RBF), ordinary Kriging (OK) and collaborative Kriging (CK) to interpolate the precipitation and temperature, and compared with simulation results using cross validation method. The results show that the CK considering latitude and elevation has the most effective, error estimates of precipitation and temperature are: CK < OK < RBF < IDW, by analyzing the precipitation results, the precipitation and temperature show a trend of gradually increasing from the south to the north, and present a clear zonal latitude, the precipitation is mainly decided by latitude and elevation, the temperature is mainly affected by latitude, monthly average temperature has certain seasonal patterns with longitude and latitude.
