合肥市2018年度农业气象条件分析

Analysis on Agrometeorological Conditions of Hefei in 2018

利用合肥市国家观测站(骆岗机场)2018年度常规气象资料,采用时序法分析了合肥市2018年逐日日平均气温、降水量和日照时数等气象要素。结果表明,全年平均气温较常年偏高0.8°C,其中春季创历史同期新高;年平均降水量1 310 mm,较常年偏多20%,春季出现较强连阴雨;年平均日照时数较常年偏少26 h,日照时数分布不均,夏季显著偏多。主要农业气象灾害有台风、暴雨、高温干旱、连阴雨等,局地灾害重但总体上未出现大范围持续性强的农业气象灾害。2018年农业生产气象条件总体上利略大于弊。

Based on the routine meteorological data of Hefei National Observatory(Luogang Airport) in 2018, the daily average temperature, precipitation and sunshine hours of Hefei in 2018 were analyzed by time series method.The results showed that the annual average temperature is 0.8 higher than that of the perennial year, with a record high in spring;the annual average precipitation is 1 310 mm, which is 20% more than that of the perennial year;the annual average sunshine hours are 26 hours less than that of the perennial year;the distribution of sunshine hours is uneven;and the summer season is significantly more than that of the perennial year. The main agrometeorological disasters were typhoon, rainstorm, high temperature and drought, continuous rain. Local disasters were serious, but generally there were no agrometeorological disasters with strong sustainability on a large scale. In general, the advantages of meteorological conditions for agricultural production in 2018 were slightly greater than the disadvantages.
