季节性周期预测法在建立降雨预报模型中的应用

Applying the method of season forecast to building up the model of forecasting rainfall

利用季节预测法建立了三江平原井灌水稻区大气降雨预报模型 ,经与实测值比较 ,精度较高。可在灌区降雨预防及灌溉管理中应用。同时对于该地区推求水稻净灌溉需水量、灌溉定额、优化灌溉制度、节约地下水资源。

The paper applied the method of season forecast to building up the model of rainfall forecasting.Through comparing with the practical value,the precision of the model is high.It can be used for forecasting rainfall of irrigation area and irrigation management.
