摘要
采用新疆地区1954—2006年14个气象站的系列资料,通过小波分析的方法,分析了新疆53a(1954—2006年)雨季降水的周期变化;用t检验分析了强ENSO对新疆雨季降水的响应关系。结果表明,新疆雨季降水周期变化与ENSO周期变化相比具有明显的滞后性;新疆大部分地区雨季降水与ENSO关系显著。
Based on the monthly and annual rainfall data of 14 weather stations in Xinjiang region from 1954 to 2006, by using the wavelet analysis method, the periodic variation of rainy season precipitation in Xinjiang during 53a （1954-2006） is analyzed, and the response relationship between strong ENSO and the rainfall of rainy season in Xinjiang is analyzed with T-test. The result shows that the periodic variation of rainy season in Xinjiang compared with the periodic variation of ENSO has obvious lagging nature, the response relationship between the rainfall of rainy season in the most areas of Xinjiang and the strong ENSO is significant.
