中文摘要: 采用1951—2005年广州气温以及NCEP再分析资料，分析了近55年来广州市气温变
化情况以及成因。结果表明：广州气温在1980年代中期以来呈显著上升趋势，其中冬季最低
气温
增温最为显著；冬季低温（≤5℃）日数明显减少，夏季高温（≥35℃）日数则显著增加；5
00hPa高度场的异常升高、冬季风和夏季风强度的减弱与广州气温的升高有直接的关系，而
城市化进程同样也在广州气温尤其是冬季最低气温的增温中起到不可忽视的作用。
Abstract:By use of Guangzhou temperature and NCEP reanalysis data from 1951-200
5, the change of Guangzhou temperature and its probable cause is studied. Eviden
ce suggests that Guangzhou temperature shows an obvious increase since the middl
e of 1980s, with the most prominent trend in winter minimal temperature. The num
ber of low temperature day (≤5℃) in winter decreases obviously and that of hig
h temperature day (≥35℃) in summer increases prominently. Results also show th
at the increase in Guangzhou temperature has a direct relationship with the heig
ht of 500hPa fields and the weakening of winter and summer monsoon. And the r
ole of urbanization process can’t be neglected in the increase of Guangzhou tem
perature, especially in winter minimal temperature.
