摘要
根据太原市6县区气象站气温观测资料,采用现代气候诊断方法,分析了太原近郊和远郊热岛强度的月、年和年代际的变化规律,探讨了不同温度的热岛强度特征。结果表明:太原近郊的月热岛强度和年热岛强度均低于远郊;近郊和远郊热岛强度的变化趋势一致;冬季热岛强度最强,夏季热岛强度最弱;近30年太原热岛强度逐年增强;热岛效应都主要表现在最低气温的增加上;夏季,有1/3的年份会出现城市凉岛现象等。
According to air temperature observation data of six county/district meteorological stations in Taiyuan City, and adopting modern climate diagnosis method, this paper analyzes the monthly, iannual and decadal changing regularities of heat -island intensity in suburb and suburban areas of Taiyuan City, and probes into the features of the heat -island intensity under different temperatures. The Results show that the monthly heat-island intensity and annual heat -island intensity in suburb areas of Taiyuan are lower than that in suburban areas of Taiyuan City, but the changing trends of the heat-island intensity in suburb and suburban areas are consistent; the heat-island intensity in winter is the strongest, while the heat -island intensity in summer is the weakest; the heat -island intensity of Taiyuan City has become stronger and stronger year by year; the heat-island intensity is mainly manifested in the increase of the minimum temperature; and in winter, the cool-island phenomenon will occur in one-third of the years.
