摘要: 利用西安市54a的降水量、气温及日照时数资料对其气候变化特征进行分析,得出:西安市气温在波动中呈现上升的趋势,1990年比1951年气温升高了0.72℃,气温升高主要发生在1985年以后。降水量在波动中呈下降趋势,与西北地区其它4大城市比较,1985年以来西安市气温升高、降水减少、日照时数下降,有向暖干化方向发展的趋势,而兰州、乌鲁木齐、西宁、银川有向暖湿方向发展的趋势。

关键词: 西安市, 气温, 降水, 日照时数, 气候变化

Abstract: Based on the observed data of precipitation,temperature and sunshine time from 1950 to 2003 in Xi'an,the climate change characteristics were analyzed.The results showed that the temperature of Xi'an had an increasing trend,which increased 0.72℃ from 1951 to 1990.Temperature increasing mainly took place after 1985.The precipitation of Xi'an had a decreasing trend with fluctuation.Compared with other 4 cities like Lanzhou,Ulumuqi,Xining and Yinchuan in the Northwest China,the temperature in Xi'an had an increasing trend,while the precipitation and sunshine time had a decreasing trend.The trend of climate change in Xi'an was becoming warmer and drier,while that in Lanzhou,Ulumuqi,Xining and Yinchuan was becoming warmer and wetter.
