中文摘要:
      年际及年代际时间变率是当代气候研究的重要问题之一,通过对近百年热带太平洋海温资料做子波分析发现,20世纪50年代以来的海温升高及频繁发生的ENSO事件伴随着海温年代际时间尺度背景场的明显改变,同时还研究了其年代际及年际时间尺度时间变率特征。
英文摘要:
      The variability inter-decadal and inter-annuales of the SST in tropical Pacific in the last 100 years have been found by using the wavelet trans form. It has been also found that the inter-decadal scale period which is considered as the background filed had been changed obviously while the SST in tropical Pacific was increasing clearly and more and more ENSO events are occurring from 1950s. The characters of inter-decadal variability and inter-annual variability have been studied too.
