| 摘 要： | 利用常规气象观测资料和NCAR/NCEP再分析资料,分析了2009年11月中旬广东省强冷空气的特点和成因,结果表明:此次强冷空气的特点是出现时间早、日平均气温低、气温回升缓慢、降水偏多;发生的可能气候成因是大气环流从纬向型调整为经向型,以及厄尔尼诺事件的间接影响。

| Abstract: | Based on the meteorological observation data and the NCAR / NCEP reanalysis data, the characteristics and the causes of strong cold air in Guangdong during mid-November 2009 are studied.The results show that,the strong cold air occurred earlier, the daily average temperature was lower and rising slower, and the precipitation of the process was more than normal; the climate cause was the atmospheric circulation adjustment from the zonal pattern to meridional one,and the indirect effects of El Nino event. |
