利用1961~2014年春季宁夏20个气象站的降水及NCEP再分析等资料,重点分析了不同分布型El Nio事件次年宁夏春季降水的差异。结果表明:由于El Nio事件在1990年代以后主要转为中部型,宁夏春季降水对El Nio的响应也发生了变化,由之前在El Nio发生次年春季降水偏多,转为次年春季降水偏少。东部型和混合型El Nio事件次年春季,500 h Pa高度距平场上欧亚中高纬地区环流分布及700 h Pa水汽输送条件,均有利于宁夏出现降水;而中部型El Nio事件次年春季,青藏高原南侧以偏西风为主,青藏高原东南侧相对湿度较低,不利于宁夏春季出现降水。 Based on the data of precipitation and NCEP reanalysis from 20 stations in Ningxia in the spring of 1961 ~ 2014, the differences of precipitation in Ningxia in different distributional El Nio events are analyzed emphatically. The results show that the response of El Nio to the spring precipitation in Ningxia also changed due to the El Nio event changing to the middle type mainly after the 1990s, Less rainfall for the following spring. In the spring of the eastern and mixed El Nio events, the circulation distribution in the 500-h Pa geopotential height anomalies at mid-high latitudes in Europe and 700 hPa and the vapor transport conditions at 700 hPa are favorable for precipitation in Ningxia; while the central El Ni o In the following spring, the south of the Qinghai-Tibet Plateau is mainly westerly with relatively low relative humidity on the southeast of the Qinghai-Tibet Plateau, which is detrimental to precipitation in Ningxia spring.
