摘要
利用1953—2015年深圳国家基本气象站气候平均值资料统计分析了近63年来深圳市的气温和降水的变化趋势。结果表明:深圳市气温平均值逐渐增大且趋势越来越明显,增暖具有明显的季节性,秋冬季升高幅度更明显;全年及后汛期降水量的气候平均值呈下降趋势。前汛期降水量的气候平均值呈增加趋势,多雨和少雨期的降水量差距十分显著;降水日数呈波动下降的趋势,并且浮动幅度越来越小。
Climatologically averaged data from national basic meteorological stations in Shenzhen for 1953 to 2015 are used to run a statistical study of the variation trends of air temperature and precipitation in the city for the period. The result is shown as follows. The temperature mean has been increasing gradually and significantly, warming is of substantial seasonality with a much more obvious rising amplitude in autumn and winter. The climatological mean of precipitation for the whole year and the annually second flood season shows a decreasing trend while that of the annually first flood season an increasing trend. The period of more rain differs much from that of less rain. The number of rain days shows a trend of reduction in ever-decreasing fluctuation.
