本溪地区气温降水空间分布特征分析

利用本溪地区2006～2007年区域自动气象站气温及降水资料,从年、季平均气温、平均最高气温、平均最低气温及降水量对其空间分布进行了较为全面的分析。结果表明:气温空间分布特征总体为西部地区呈自西向东递减,东部地区呈自南向北递减的分布规律。春、冬季平均气温和年平均最低气温大体与年平均气温分布一致,夏、秋季平均气温略有差异,年平均最高气温分布不太明显。降水空间分布特征总体上呈由东南向西北方向递减趋势,东部地区降水明显多于西部地区。

The Spatial Distribution of Temperature and Precipitation in Benxi,Liaoning Province

Based on the temperature and precipitation data from 2006 to 2007 in Benxi territorial automatic weather stations, the spatial distributing changes were analyzed from the annual and seasonal mean, maximum, minimum temperature and rainfall. The results showed that the temperature characteristics is an decreasing trend from west to east in western areas, and from south to north in eastern areas. For the annual mean and minimum temperature in spring and winter the tendency was general same with the annual mean temperature, the little difference in summer and autumn, for the annual mean maximum temperature the distribution was not obvious. The precipitation characteristics was an decreasing trend from southeast to northwest, the precipitation in eastern areas was more than in western areas.
