典型相关统计方法及其在四川气温场分析中的应用

Typical correlation statistical method and its application to temperature field in Sichuan

利用典型相关理论,分析了四川7月气温与当年前期1-5月气温场之间的关系。分析结果表明1月川西和川东北高温与7月川西和川东北高温呈正相关,盆地中西部1月低温与盆地中西部7月高温呈反相关。2至5月盆地东北部低温与7月同地区高温呈反相关,2至5月盆地南部高低温与7月同地区高低温呈反相关。

By the typical correlative theory the relation between the July temperature and that from January to May in the same year is analyzed. The results show that the high temperature of the western and northeastern Sichuan in January is positive correlative with that in the same area. The low temperature of the central and western Sichuan in January is negative correlative with the high one in the same area. The results also reveal that the low temperature from February to May is negative correlative with the high one of July in the northeastern Sichuan and the temperature from February to May is also negative with the July temperature in the southern Sichuan.
