| 摘 要： | 运用天水市7个国家气象站1961—2008年温度极值及相关天气现象资料，分析了其对气候变化的响应。结果表明，自1961年以来，该地年平均最高气温以0．36℃／10年的速度升高；年平均最低气温以0．40℃／10年的速度升高。增温幅度最大的时期出现在20世纪80年代以后。年最低气温≤0℃的日数以0．33d／年的速度递减；年平均最低地表温度以0．44℃／10年的速度增加；年极端最低地表温度以1．40℃／10年的速度增加；年结冰日数以0．33el／年的速度减少。温度极值及相关天气现象的变化必然会影响到种植业的布局及社会生活的许多方面。 |

| Abstract: | Based on data of extreme value of temperature and its correlative weather phenomenon in 7 national weather stations which located in Tianshui city from 1961 to 2008,their response to climate change had been analyzed.The result showed that the mean annual maximum temperature and mean annual minimum temperature increased by 0.36 ℃ and 0.40 ℃ every ten years respectively.The time of maximum extend of temperature rising was in later of 1980's.It also showed that the annual days which less than 0 ℃ decreased by 0.33 a year.It indicated that the mean surface minimum temperature and extreme surface minimum temperature increased by 0.44 ℃ and 1.40 ℃ every ten years respectively and the annual days of ice-up decreased by 0.33 d a year.There will be a big influence of variation of extreme temperature and its correlative weather phenomenon on crop farming arrangement and many aspects of social life. |
