摘要
基于衡水市11个县(市、区)国家气象观测站1978—2022年逐日观测数据,依据夏玉米生育期,分析了衡水市暴雨、冰雹、大风、高温4类主要气象灾害的时空分布特征及变化趋势。结果表明,1978—2022年衡水市夏玉米生育期暴雨年际变化总体呈上升趋势,上升趋势不明显,空间分布呈由北向南逐渐递增特征;大风灾害主要集中在播种期至大喇叭口期,年际变化呈下降趋势,空间分布呈由中部地区向周边逐渐增多的特征;冰雹灾害最多出现在6月,年际变化呈下降趋势,下降速率为0.14 d/年,空间分布呈东部多、中北部较多、中南部和西北部少的特征;高温日数主要集中出现在6月,年际变化总体呈上升趋势,上升趋势不明显,高温日数最多地区位于枣强县中部,较多地区为枣强县中西部、武强县东部。
Based on the daily observation data from the national meteorological observation stations of 11 counties(cities,districts)in Hengshui City from 1978 to 2022,according to the growth period of summer maize,the temporal and spatial distribution characteristics and change trend of four major meteorological disasters in Hengshui City were analyzed,including rainstorm,hail,gale and high temperature.The results showed that the interannual variation of rainstorm during the growth period of summer maize in Hengshui City from 1978 to 2022 showed an overall upward trend,and the upward trend was not obvious.and its spatial distribution was gradually increasing from north to south.Gale disasters were mainly concentrated in the sowing period to big trumpet period,the interannual change showed a downward trend,and its spatial distribution was gradually increasing from the central region to the periphery.Hail disasters occured in June at most,the interannual change showed a downward trend,and the decline rate was 0.14 d/a.The spatial distribution of hail disasters was characterized by most in the east,more in the north and central,and less in the middle-south and northwest.The high temperature days mainly occurred in June,the interannual change shows an overall upward trend,and the upward trend was not obvious.The area with the most high temperature days was located in the middle of Zaoqiang County,with more areas in the midwest of Zaoqiang County and the east of Wuqiang County.
