| Abstract: | Under the background of global warming,recently meteorological disasters and their evocable socio-economic losses have risen,since the extreme weather and climate events occurred frequently.For disaster prevention and reduction,it has guiding significance to deeply understand the characteristics of extreme air temperature and precipitation events which are closely related to the social life.This paper calculated the probability density values of extreme daily air temperature and precipitation through their ... |
