摘要
通过对海温与云南全省、云南东部和云南西部5月雨量的相关分析发现:海温对云南5月降水在时空上有很好的相关.5月降水与头年11月和同期太平洋海表温度存在有相同的‘- + - +’的相关分布型.印度洋北部对云南东部的影响更显著,而大西洋北部对西部的影响更显著.西部5月雨量与海表温度的相关总体不如东部的好,西部与东部最大的差异是在热带太平洋上.通过头年1月南大西洋海温可对来年云南5月降水进行预测.
The correlation coefficients between the sea surface temperature and the May rainfall of Yunnan,between that and the May rainfall of East Yunnan,and between that and the May rainfall of West Yunnan were calculated and analyzed with the global sea surface temperature data provided by NCC/NCAR and the May rainfall data of Yunnan.The results indicated that,there is stronger temporal and spattal correlation between them.The( - + - + )pattern between sea surface temperature in previous November and May the rainf...
