Analysis of Urban Climate in Baoshan City of Yunnan
摘要
Abstract
By using meteorological data of urban area of Baoshan City and its suburb area (Changning County) during 1964-2010, the urban climatic variation in Baoshan city is analyzed in this paper. A comparison of temperature and relative humidity between the two areas is made, and the results show that: the density of heat island and dry island in Baoshan was increasing year by year. The urban heat island reached the strongest in spring, whereas the weakest in autumn. As for the daily changes, the strongest heat island occurred at night( 2 am) and the weakest in the afternoon (2 pm). However, the density of urban dry island showed an appositive change. The method of Gray Correlation Degree Analysis is applied to analyze the density of urban heat island and dry island in Baoshan city, and the results suggest that: population was the greatest influential humanistic factor of urban heat island and dry island, and the major natural factor affecting urban heat island was precipitation, while that affecting urban dry island was total cloud amount.关键词
