摘要
利用1951~1995 年长江三角洲的气象观测资料,研究分析了该地区近45 年来气温、降水及各种极端温度的变化、气候变率及主要气象灾害。结果表明,本区域近几十年来的气候变化趋于暖冬、凉夏,气温、降水变率加大,气象灾害频繁增多的特点十分明显。
Based on the meterological observation data in the Yangtze Delta in 1951~1995, this paper analyzes the climate change of meteorological clements such as mean air temperature and precipitation, maximum and minimum air temperature, major meteorological disasters. Results show that there are obviously a warming trend in winter,a cooling trend in summer, an increasing in the variability of mean air temperature and precipitation,and a rising in meteorological disaster frequency.
