摘要
全球气候变化导致极端气候事件频发,选择描述极端气候事件的相关指标,利用Mann-Kendall趋势检验法等对深圳市1953-2012年极端气候指标进行分析。结果表明:总体上深圳市降水频次与极端降水量均呈现起伏不定的变化规律,四季极端降水量主要集中在夏季,全年和四季降水量均没有明显的变化趋势。深圳市极端气温总体呈现较为显著稳定的变化状况;极端高温事件不断增加,极端低温事件不断减少,且趋势显著,同一季节的气温差异性较大,且差异性呈现出比较显著的加大趋势。
Extreme climate events are frequently occurred due to global climate change. The paper chose the relevant indexes which describe extreme climate event and used Mann-Kendall trend test method to analyze extreme climate indexes in Shenzhen from 1953 to 2012. The results show that the precipitation frequency and extreme precipitation in Shenzhen presented the change law of ups and downs. The extreme precipitation of four seasons concentrated in the summer,the annual and seasonal precipitation had no obvious change tendency. The change of extreme temperature in Shenzhen is significant and stable,the extreme high temperature events continuously increase,the extreme low temperature events continuously decrease,and the trend is notable,the temperature difference of same season is greater,and the difference appears a significant increase trend.
