作物生长模型Oryza V3实战19：场景模拟常见问题及解决

1、运行oryza3.exe报气象数据不可用

        报：Rain not available, value set to zero, (patch DvK, Jan 1995)

        一开始以为是水气压与饱和水气压计算不匹配降雨量，导致数据不可用；后调整二者的公式，也不见效果。

        再查看其设计文档：After initialization, the presence of the requested weather data is checked at each rate calculation step (ITASK.EQ.2) and at the start (ITASK.EQ.1) and end (ITASK.EQ.4) of each simulation run. The weather data are read from the data file by the WEATHER system in FSE and passed to the subroutine MODELS (Section 2.3).
