Study on soil moisture grid point forecast in Henan province.

The regional climate model Reg CM3 driven by global model T213 was run for 7d to forcast,and then the results were used for soil moisture prediction model to make grid soil moisture prediction.The results showed that the correlation coefficien in three times was all above 0.65 and both the average standard deviation and mean standard error were below 20%,suggesting that this model has certain analog capability in soil moisture simulation in Henan province.
