STUDY OF SUMMER CLIMATE BASE STATE IN CHINA

Nanjing Institute of Meteorology, Naming 210044, China

摘要

摘要: 利用1881年～1998年29个观测站的夏季降水、气温资料,研究了我国东部夏季降水、气温大于30年的慢变平均值(气候基本态)的变化特征。用经验正交分解方法研究了夏季降水与气温的气候基本态的特征模态及时间演变规律。结果表明,我国东部夏季降水、气温的气候基本态与我国夏季天气及夏季大气活动中心的气候基本态关系密切。

Abstract: Using summer rainfall and mean temperature data of 29 stations in China from 1881~ 1998, study is undertaken of more than 30 years slowly-varying mean, called climate base state,of the summer rainfall and temperature in China in the past 118 years. The characteristic mode and temporal evolution of the base state are investigated using Empirical Orthogonal Function(EOF)analysis. The research shows a close relation in the time scale of base state between the Summer rainfall and temperature in China and active atmospheric centers in summer.
