年降水量
In the northwest to southeast direction, annual precipitation increases, leading to transition from arid, semi-arid to sub-humid climates.
從西北向東南,年降水量逐漸增加,氣候由干旱、半干旱向半濕潤過渡。
平均降水量
The mean annual precipitation in Northeast China is 489mm, successively decreasing from southeast area to northwest area, which is 635mm, 481mm, and 355mm, respectively, in the east, central, and west regions.
東北區(qū)多年平均降水量為489mm，從東南向西北遞減，多年平均東部區(qū)、中部區(qū)和西部區(qū)的降水分別為635mm，481mm，355mm。

The models can reproduce the annual precipitation sequence and monthly precipitation sequence. And then the regional aridity index can be estimated statistically,in addition,they can reproduce the characteristic of history precipitation series.
這兩類模型分別用于生成模擬年降雨量序列和月降雨量序列作為地區(qū)干旱指標(biāo)序列，從而對所研究地區(qū)干旱特征量的統(tǒng)計特性進(jìn)行估計，并對已發(fā)生的地區(qū)干旱的重現(xiàn)期進(jìn)行識別。
