| 摘 要： | 为了解气候增暖情况下,无锡地区极端最高和最低气温的气候特征,用阈值检测方法对无锡市1959-2007年的日最高气温、日最低气温进行了研究,分析了极端事件的发生规律,得出主要结论:(1)从年代际看,不论是日最高气温或日最低气温,2001-2007年偏高事件最多,偏低事件最少.(2)最低气温从1980s初开始稳定上升.(3)在3、5、7、12月比较容易出现异常的气温.月内异常气温出现次数多少主要与季节更替和天气系统的转换有关.(4)日最低气温不论冬春夏秋,都是明显升高.日最高气温冬、春、秋季呈升高趋势,而夏季震荡加大.即在夏季,日最高气温偏高的事件增多,日最高气温偏低的事件也增多. |
| 关 键 词： | 极端气温 极端事件 阈值检测 |

| Abstract: | Checking Wuxi's daily high and low temperature with threshold value method,analyzing the rules of the event occurrence,several results are concluded.(1) In decade dimension,the 2 000th century has the most high-leaning events and the least low-leaning events.(2) The low temperature had been rising from the 1980.(3) Early or late seasonal change and weather system change mainly decide the number of the event.(4) In summer,the high-leaning event number of the high temperature is increasing,and the low-leaning... |
