本文利用奇异值分解方法对河南省降水与热带太平洋 El Nino区域的海温的时滞遥相关进行分析 ,分析结果表明 :6月河南降水距平与各个 El Nino区前一年 7～ 12月及当年 1～ 2月海温距平有显著负相关 ;7月河南降水距平与各El Nino区前一年 7～ 12月及当年 1～ 2月海温距平有显著正相关 ,10月份降水距平与 Ninol+ 2和 Nino4区海温距平有正相关 ,4月河南降水与前一年 1月 El Nino4区显著负相关
In this paper, we use the singular value decomposition method to analyze the time-lag between the precipitation in Hainan Province and the sea surface temperature in the El Nino region of the tropical Pacific Ocean. The results show that the precipitation anomaly in Henan Province in June is similar to that in each El Nino region from July to December of the previous year and There was a significant negative correlation between SST anomalies from January to February in that year; meanwhile, the precipitation anomalies in July in Henan Province were significantly and positively correlated with SST anomalies from July to December in the previous year and January to February in each El Nino area. There was a positive correlation between anomalies and SST anomalies in Ninol + 2 and Nino 4 areas. April precipitation in Henan was significantly negatively correlated with El Nino 4 in January of the previous year
