摘要
为了进一步研究陇东气候特征及气象灾害,利用庆阳市2018年气温、降水、日照及灾害性天气等气象资料,对其时空分布特征、气候背景\,主要灾害事件、灾情等进行分析。结果表明:庆阳市2018年气候特征为全年平均气温略偏高,极端气温未突破历史极值,春季正常略偏高,夏、秋、冬季正常略偏低;降水量偏多,春、夏、冬季偏多,秋季偏少;日照时数略有偏少,春、夏、冬季略偏少,秋季略偏多;3个要素的地域分布均相差明显。2018年出现的主要气候事件为1月暴雪、4月低温冻害、5—9月冰雹、6—8月暴雨和短时强降水,灾害天气以局部为主,暴雨洪涝造成的气象灾害事故偏多,冰雹、低温冻害对农作物造成严重危害。
In order to further study the climatic characteristics and meteorological disasters of Longdong area,the spatial and temporal distribution characteristics,climatic background,major disasters and weather events were analyzed by using the meteorological data of Qingyang city in 2018 including temperature,precipitation,sunshine and disastrous weather.The results show that the climate characteristics of Qingyang city in 2018 are as follows:the annual average temperature is slightly higher;the extreme temperature has not broken the historical extreme value;the normal temperature in spring is slightly higher,and the normal temperature in summer,autumn and winter is slightly lower.Precipitation in spring,summer,winter is higher,while in autumn is lower.Sunshine hours in summer,winter are slightly less,while in autumn is slightly more.The geographical distribution of the three elements are significantly different.The major weather events were blizzard in January,freezing damage in April,hail from may to September,rainstorm and short heavy rainfall from June to August.Disaster weather is mainly at local area,mainly heavy rain and floods caused by meteorological disaster accidents,which caused serious damage to crops.
