【摘要】 以前人工作为基础 ,建立了常年逐日气温 (包括平均、极端最高和最低气温 )、日照时数、降雨量、太阳辐射等气象要素的生成模型 ,并对降雨量和太阳辐射模型进行了改进 ,取得满意效果。采用VB6 0作为系统开发工具 ,研制成基于Windows操作平台的作物模拟中的常年气候数据生成子系统。利用南京 4 0年和郑州 30年的历史气候资料 ,分别对该系统进行检验 ,模拟值与实际情况相符 ,相关系数分别为 0 93和 0 89。

【Abstract】 A climate generator model,which can be used to simulate weather factors such as daily temperature,sunshine duration in hour,rainfall,solar radiation in a normal year,was established based on the previous work.The daily temperature includes the mean,maximum,and minimum temperature in a day.The authors improved particularly the daily rainfall model and the daily solar radiation model,and obtained a good simulating effect.The weather data generating subsystem in crop growth simulation was also accomplished with the development tool of VB 6 0.It can be run on the Windows platform.Validation of this subsystem in the areas of Nanjing and Zhengzhou showed that the results were good and there was a good agreement between values simulated and values observed.The correlation coefficients between values simulated and actual values are 0 93 and 0 89 orderly in Nanjing area with the historical weather data from 1951 to 1990 and in Zhengzhou area with those from 1951 to 1980
