金华地区气候态变化特征及极端气候敏感区域分析

Characteristics of Climate Change and Extreme Weather in Central Sensitive Area of Zhejiang

  • 摘要: 基于金华市1968—2020年逐年气温、日照时数、降水量和降水日数数据,采用常规气象统计方法,对金华地区气候态变化特征及极端气候敏感区域进行分析,结果表明:(1)不同气候态下金华地区平均气温、降水量均呈增加趋势,且分别在Ⅲ态、Ⅳ态最明显,而日照时数、降水日数则呈减少趋势,且分别在Ⅱ态、Ⅳ态下最明显;但随着Ⅱ~Ⅳ态的转变,平均气温的增温效应、日照时数和降水日数的减少趋势则均在减弱,降水量的增加趋势则先增强再减弱。(2)金华地区平均气温呈永康兰溪暖、浦江冷的格局,日照时数表现为金华义乌多、兰溪永康少的特征,降水量呈现出武义浦江多、义乌东阳少的分布,降水日数具有南多北少的特征。随着气候态变化,气温、日照时数、降水量、降水日数整体呈明显增高、减少、增多、减少趋势。(3)气候态的变化使得金华地区平均气温等级由低向高移动,日照时数等级由高向低移动,降水量等级由4级向3级来回移动,降水日数等级无明显变化。(4)随着气候态转变,除兰溪外整个金华地区均是极端气温的敏感区,兰溪、义乌是极端日照时数的敏感区,极端降水、降水日数基本无敏感区域。

     

    Abstract: Conventional meteorological statistics methods were used to figure out the annual temperature,sunshine hours,precipitation and precipitation days at Jinhua Meteorological Observatory from 1968 to 2020,and to analyze the characteristics of climate change in Jinhua region and the sensitive areas for extreme climate.The results showed that:(1)Under different climate states,the average temperature and precipitation in Jinhua showed increasing trends,and were the most obvious in states Ⅲ and Ⅳ,while sunshine hours and precipitation days showed decreasing trends,and the most obvious in states Ⅱ and Ⅳ;however,with the changes of the Ⅱ-Ⅳ state,the increase of average temperature,the decreases of sunshine hours and the number of precipitation days all weakened,and the increase of precipitation first increased and then decreased.(2)The average temperature in Jinhua was high in Lanxi and was low in Pujiang,and the sunshine hours were more in Yiwu but less in Yongkang and Lanxi.The precipitation was more in Wuyi and Pujiang but less in Dongyang and Yiwu,the precipitation days were more in the south but less in the north.With the change of climate state,the above four elements showed a significant trend of increasing,decreasing,increasing,and decreasing,respectively.(3) Due to the change of climate state,the average temperature level in Jinhua area moved from low to high,the level of sunshine hours moved from high to low,the precipitation level moved back and forth from 4 to 3,and there was insignificant change in the level of precipitation days.(4) With the change of climate state,the whole Jinhua area except Lanxi was sensitive areas for extreme temperature.Lanxi and Yiwu were sensitive areas for extreme sunshine hours,and there were basically no sensitive areas for extreme precipitation and precipitation days.
