广东冬季气温变化的气候诊断分析

CLIMATOLOGICAL DIAGNOSIS Of WINTER TEMPERATURE VARIATIONS IN GUANGDONG

利用广东省３６个地面站的实测资料，分析了广东冬季平均气温、最低气温的气候变化特征，包括温度变化趋势、突变、周期性，并探讨了影响广东冬季增暖的可能因素。得出：广东冬季气温具有增温趋势，特别是最低气温。冬季广东最低气温从６０年代下半叶开始上升，８０年代以来，增温幅度有所增大，进入暖期。

Using the monthly mean and minimum temperature data of the 36 observation stations in Guangdong, the climatological features of the temperatures have been analyzed, including characteristics of trends,abrupt changes and periods. And the possible affect factors on the winter warming in Guangdong have been discussed. The results show that the winter temperatures,particularly the monthly mean minimum temperatures in Guangdong,have a warming trend. The rise of the winter minimum temperatures in Guangdong began in the second half of 1960 ’s and the warming was more evident since the 1980 ’s.
