We divided the global june - august precipitation field into 34 subareas and pointed out that there exists evident teleconnection among the june - august precipitation in these subareas 用reof方法将全球陆地6 - 8月降水场分成34个大尺度降水分区。
The precipitation forecast was improved quantitively , the forecasted severe convection area was consistent with the observation , and the spin up was reduced as much as 25 % 试验表明,预报的降水场有了相当程度的改善,预报强降水落区与实况非常接近, spinup问题改进了25 。
Numerical experiments results on modeling the rainfall , show that : l ) the rainfall field modeled is improved and much similar to real rain field when tbb data is assimiliated into initial fields 同化模拟试验结果表明,卫星云图资料同化后模拟预报的降水场结果有了相当程度的改善,预报的强降水与实况比较接近。
The calculating circle is very near compared with the fact . and many physical diagnose quantities thus as high vertical movement , q - vector divergence , 0 - 6 km shear etc . all contact with the rainstorm 在降水场的模拟中,降雨带的范围与实况接近,强降水中心位置和强度略有偏差,通过修正意见对提高预报准确率会有很大帮助。
We also use the data from 1920 - 2000 , which were made by chen through interpolating the data of precipitation records in global land ( prec / l ) to replace the lack records of the global land precipitation dataset updated by or 还用到了陈绿文利用prec / l资料将hulme的资料插补为完整的1920 ? 2000年全球陆地降水场资料,研究了1920 ? 2000年期间发生enso事件年份的全球及区域降水异常特征。
