Climatic Characteristics of Thunderstorm in Ji' nan in the Last 50 Years
摘要
Abstract
By using thunderstorm data of Ji' nan six stations, variance trends of yearly and monthly thunderstorm days were analyzed including variance trends of the first and the last thunderstorm days and their absolute variability and opposite variability to investigate the climatic characteristics of thunderstorm and its evolving trend in Ji' nan area. As seen by inter-annual variation, thunderstorm days in Ji' nan City reduced as a whole, annual mean thunderstorm days of Ji' nan station undulated with its mean value, while annual mean thunderstorm days of other stations reduced with a linear inclination rate of -2.5 ～ -3.9 d/10 a. Thunderstorm only occurecd from March to November and the frequent thunderstorm period was from June to August most was July, next was August. The first thunderstorm day over submountain plain in mid-region was the earlier than that in north alluvial plain or south hilly land, while the last thunderstorm day of it was the latest so that thunderstorm period over submountain plain was longer. Either the first thunderstorm days or the last thunderstorm days in south hilly land were stable compared to plain terrain.关键词
