摘要
利用 1 95 5 - 1 997年陕西渭北地区 5个县、市的气温和降水资料 ,对近 43年来陕西渭北地区气候变化特征进行了分析 .结果表明 ,近 43年来 ,陕西渭北地区温度、降水的变化呈明显多重周期波动 ,年平均气温上升 ,降水量减少 ,变旱趋势明显 。
Based on the data of the annually mean air temperature and the annually precipitation, seasonal mean air temperature and seasonal precipitation, maximum and minimum air temperature from five stations in Weibei dry land of Shaanxi province in China from 1955 to 1997,the climate change and its characteristics of this regions in recent 43 years have been analyzed and studied comprehensively.
