摘要
根据江西高速公路交通站2014—2018年逐分钟实况监测数据,得出江西高速公路沿线雾近年来呈现出增加的趋势,局地性特征明显,浓雾和强浓雾占比高达89.1%,以春、冬两季为多,11—1月是雾的频发阶段,8—10月是雾少发阶段,5—7月为特强浓雾频发月份,占其总发生比率达61.1%。00:00—05:00是雾形成的高发时段,08:00—17:00是雾频次最低的时段,06:00—09:00雾的消散占比达到53.8%。雾的维持时间均不超过24 h,94.7%的大雾只能持续3 h,88.7%的强浓雾维持时间在9 h以内,76.5%的特强浓雾维持时间在7 h以内。泰井路桥隧管理公园为大雾服务的特别关键性路段,得出了各站的大雾服务特别关键期。
