摘要
利用1961年1月1日至2000年12月6日共40年我国551站的气温资料、国家气候中心气候系统诊断预测室74项1951年1月至2000年12月环流特征量资料以及NCEP 1960年1月1日至2009年12月31日500 h Pa再分析资料。采用资料再分析处理后提取副高指数,然后用我国551站1961年1月至2000年12月的月气温分别与同期的月副高西伸脊点指数、月副高强度指数、月副高脊线指数求相关系数,并对结果作T检验,找出信度为95%以上的区域。分析结果表明,西太平洋副热带高压与中国各地气温在年内和年际都确实存在较好的相关关系;在副高脊线附近,及由脊线向北直到副高北界,甚至北界以北的广大区域,副高越西伸、强度越强、脊线位置越北,当地气温越高;在副高北界以北〈15-20个纬度处和副高脊线以南的区域,副高越西伸、强度越强、脊线位置越北,当地气温越低。
The temperature data of 551 stations during January 1,1961 to December 6,2000,74 general circulation characteristics during 1951 to 2000 obtained from Diagnosis and Forecast of the National Climate Center Climate System,NCEP 500 hPa reanalysis data from January 1,1960 to December 31,2009 were involved.The data analysis after extraction of subtropical high index was matched with 551 stations in January, 1961 to December, 2000 monthly temperature respectively, and the same month side extension of the subtropical high ridge point index, on the intensity of the subtropical high index,month the ridge line of the subtropical high index correlation coefficient.The results were tested by T,and the reliability was more than 95% .Come to the conclusion of the Western Pacific subtropical high in various parts of China and the temperature in the annual and interannual are real good relationship ; In the vicinity of the subtropical high ridge and ridge to the North until the subtropical high is bounded on the north by ,even is bounded on the north by vast areas of the North ,the Deputy High extends westward ,the stronger the intensity ,the ridge line position of North Vietnam, the local temperature higher;In the northern boundary of the subtropical high 15 to 20 latitudes, and the ridge line of the subtropical high areas to the south, the Deputy High extends westward, the stronger the intensity, the ridge line position of North Vietnam, the local temperature is lower.
