In order to study the effects of extreme weather conditions on the growth of GongCheng persimmon, 60 years of meteorological data and the basic cultivation information of persimmon over the years in Gongcheng County were collected and analyzed using factor corresponding analysis method, so as to study the extreme weather conditions, the influence mechanism on persimmon industry and the de- fense measures. The extreme weather conditions that have great effects are the continuous low temperature in spring, high temperature in summer, strong wind, hail, rainstorm, drought, and frost, which can affect the persimmon tree vigor, fruit bearing rate, plant diseases and pests as well as the quality of fruit. Focusing on mete- orological service, it needs to avoid the meteorological disasters as far as possible from orchard construction to management to ensure high quality and yield of persimmon.展开更多
桂林作为国际化旅游城市,极端天气造成的灾害会给桂林社会经济的可持续发展带来显著的负面影响。本文收集整理1957—2015年桂林市13个国家级气象站的资料,采用气候倾向率的方法,对极端低温指数的趋势进行分析,造成桂林极端低温的主要天...桂林作为国际化旅游城市,极端天气造成的灾害会给桂林社会经济的可持续发展带来显著的负面影响。本文收集整理1957—2015年桂林市13个国家级气象站的资料,采用气候倾向率的方法,对极端低温指数的趋势进行分析,造成桂林极端低温的主要天气系统有阻塞高压、切断低压、南支槽等。通过分析500 h Pa高度形势场,可将影响桂林的极端低温天气系统分为阻塞高压+横槽转竖型、两槽一脊型、多波动槽脊型。展开更多
