浙江省高分辨率气温空间分布图的计算与绘制

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

以浙江省及周边74个气象站1961—2000年常规气温观测资料为基础,利用月平均气温物理经验统计模型,完成了浙江省100m×100m分辨率月平均气温、月平均最高气温、月平均最低气温空间分布的制图,分析了拟合气温的局地分布规律,并从多个角度对拟合结果进行了验证。结果表明,月平均气温的绝对误差平均值为0.09～0.59℃,平均最高气温误差为0.09～0.80℃,平均最低气温误差为0.10～0.58℃。拟合结果较好地反映了浙江山地月气温的宏观分布趋势和局地分布特征,为浙江山地气候资源的合理开发与利用提供了科学依据。

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.
