Calculation and mapping of high resolution spatial distribution of monthly air temperature of Zhejiang Province

Based on the temperature data of 74 conventional meteorological stations in Zhejiang province and the surrounding from 1961 to 2000,using the physical-experience model of monthly air temperature,we generated spatial distribution maps at a resolution of 100 m×100 m for the monthly mean,the monthly mean maximum and minimum air temperatures of Zhejiang province.The local distribution characteristics of fitting temperature are analyzed,and the simulated results are validated from several angles.Results show that the mean absolute error are 0.09—0.59 ℃ for monthly mean air temperature,0.09—0.80 ℃ for monthly mean maximum temperature,and 0.10—0.58 ℃ for monthly mean minimum temperature,respectively.The simulation can reflect to a considerable extent for the macro and local distribution characteristics of air temperature,which makes a good foundation for the reasonable development and utilization of climate resource over the rugged terrain of Zhejiang province.
