摘　　要：运用 2进小波的分解与重构技术分析了太阳活动、厄尔尼诺 -南方涛动 (ENSO)与上海地区月降水量、月均气压和月均温度序列之间的可能关系。研究结果表明 ,在不同的时间尺度 (频带 )上太阳活动和ENSO对上海的月降水量、月均气压和月均温度有不同的影响 ;在某种程度上ENSO活动对上海月降水量和月均气温的影响强于太阳活动的影响。Decomposition and reconstruction techniques of dyadic wavelet are used to analyze the possible relationship between solar activity, El Nino Southern Oscillation (ENSO), and meteorological parameters in Shanghai. Results show that solar activity and ENSO have their different affects on the monthly precipitation, monthly means of the barometric pressure and temperature in different time scales. In some extent, the effects on monthly precipitation and temperature in Shanghai due to ENSO are stronger than that due to the solar activity. Our results also show clearly and further confirm the close relation between the solar activity and ENSO in different frequency bands.
