摘要
芜湖城市的迅速发展,对该市气候产生了明显影响。我们研究对比芜湖气象台历史资料和与其距离较近的当涂气象站历史资料,发现自五十年代到七十年代,芜湖市内气温无论是10年平均或五年滑动平均都有增高的趋势。而绝对湿度和相对湿度均有降低趋势。除此之外,风速明显减小,静风频率增大,降水量减少,≥25mm的降水日数减少,总云量、低云量都有所增加,雾日也有所增加。
Due to the characteristics of Wuhu urban development, we can find some obvious influences on urban climate. By comparing the simultaneous observational data of climate in Wuhu urban area with those in Dangtu in its suburbs, the evolution of some climate elements can be found. As shown in this paper, we can see that whether from 1950's to 1970's or each 10-yr mean temperature and each 5-yr consecutive mean temperature of Wuhu show a trend of getting higher. Yet we find that both the average absolute humidity and relative humidity are lower in the city than in Dangtu, and have the tread of becoming lower from 1950's to 1970's. The other climate elements show a downward tendency, such as wind velocity, precipitation and precipitation day (≥25mm).
