摘要
本文采用1959~2010年东亚地区风场和温度场的数据资料,利用了相关分析法。定义的东亚地区范围为70E~140E,15N~55N。运用52年每年每月的急流指数与地表温度分析了东亚地区急流与地表温度的关系。研究表明:1) 东亚地区急流与地表温度存在着相关性,在7月到9月这三个月中,相关性最强,正相关系数达到了0.7,负相关系数达到了−0.45。2) 东亚地区急流与地表温度相关性最强的区域总是出现在25N~45N之间。
In this paper, the data of wind field and temperature field in East Asia from 1959 to 2010 are used, and the correlation analysis method is used. The range of East Asia is defined as 70E~140E, 15N~55N. The relationship between jet stream and land surface temperature in East Asia is analyzed by using the jet stream index and land surface temperature in 52 years. The results show that: 1) There is a correlation between the East Asian jet stream and the surface temperature, and the correlation is the strongest from July to September, with a positive correlation coefficient of 0.7 and a negative correlation coefficient of −0.45. 2) The region with the strongest correlation between jet stream and surface temperature in East Asia always appears between 25N and 45N.
