进入4月以来,我国南方多地遭遇雷电大风、冰雹等强对流天气,自南向北正陆续进入汛期,防汛抗旱防台风进入关键时期。根据气象水文预测分析,今年厄尔尼诺现象持续发展发酵,我国气象年景总体偏差,旱涝灾害可能较去年偏重。据气象部门预测,今年主汛期长江和松花江流域可能出现较重汛情,洪水威胁大。西南地区强降水引发的山洪地质灾害可能偏重,台风登陆地点集中、强度偏强,水库安全
Since April, many typhoons such as lightning gale and hail in southern China have experienced heavy convective weather. From south to north they are entering the flood season one after another, and flood control, drought prevention and typhoon prevention have entered a crucial period.
