中国长序列资料测站月降水、月均温相关联系的稳定性分析

选取我国长序列资料测站点中月降水与月均温资料较全的6个站点：西安、广州、汉口、沈阳、重庆、上海,以10a为一次成组实验,时域分辨率定为季,计算出各季月降水与月均温的相关系数,然后用相关分析和贝努里概型分析月均温与月降水之间的相关联系,初步得出我国长序列资料测站点春、夏、秋、冬月降水与月均温的相关稳定性联系。结果表明：①我国月降水与月均温在春、夏、秋、冬季均存在相关关系,以夏、秋季节最显著且为负相关,故我国常见干热或湿凉型夏、秋季;②我国华南地区春季月降水与月均温负相关关系显著,故常呈现干热或湿冷型春季;西北地区冬季月降水与月均温负相关关系较为明显,常呈现干热或湿冷型冬季。

Stability Analysis of the Correlation Between Monthly Precipitation and Monthly Average Temperature in Long Sequence Stations

Select six stations of the long sequence data of our country that there are monthly precipitation and monthly average temperature data,namely Xi’an(1931-1950,1951-2000),Guangzhou(1921-1940,1951-2000),Hankou(1911-1940,1951-2000),Shenyang(1911-1940,1951-2000),Chongqing(1921-1950,1951-2000),Shanghai(1911-2000),taking a dacade as an experiment,the hour aera resolution settle for the quarter,compute the related coefficient of monthly precipitation and monthly average temperature,using the related analysis and Bonuly Type,and then get a sequence data of monthly precipitation and monthly average.The result enunciation:①the monthly precipitation and monthly average temperature exists the related relation in our country,especially it is clear in autumn and winter;② it is clear in summer of south region of our country,preseting the dry heat or wet cool type for summer;and it is clear in spring of nouthwest region of our country,preseting the dry heat or wet cold type for spring.
