2006-2015年上海嘉定区气温和降水非均匀分布特征分析
Analysis on inhomogeneity characteristics of temperature and precipitation in Jiading district of Shanghai from 2006 to 2015
摘要
Abstract
Based on the hourly datasets from nine automatic weather station in Jiading district of Shanghai from 2006 to 2015,the inhomogeneity characteristics of the temporal and spatial change of temperature and precipitation are studied by analyzing the characteristics of diurnal,inter-annual variations and the spatial distribution of temperature and precipitation.Results reveal that the local changes and sea sonal variations of temperature and precipitation existed in Jiading district,whose maximal high temperature is centralized in all seasons but the minimum low temperature is more dispersed.The annual average temperature presented falling trend,while the annual precipitation on the whole was increasing.The southeast corner of Jiading district was the area of high temperature and relatively large precipitation,and the central region had the large precipitation and the relatively high temperature,while the temperature and precipitation are relatively low in the north part,which means that the southeast part and the central region is relatively warm-wet and the north part is relatively dry-cold.The large spatial distribution differ ence of standard deviation of temperature and precipitation shows that the inhomogeneity characteristics of temperature and precipitation in Jiading district of Shanghai is significant.The investigation on the spatialtemporal evolvement of temperature and precipitation is important for better understanding of small scale regional climate.It can also provide climate background for extreme events,refined weather forecasting as well as risk zonation of meteorological disaster.关键词
