中央气象台预报8月4日至6日，内蒙古中东部、东北地区、华北等地将出现强对流天气[1]。部分地区将有8级以上雷暴大风或冰雹，局地风力可达10级以上[1]。
下击暴流是这类强对流天气中最具破坏力的现象。首席预报员方翀介绍，下击暴流可能在几分钟到几十分钟内突然形成，影响范围仅在几十米到几公里之间，具有极强的突发性[1]。这种现象的风速可达12级以上，地面最大风力甚至可达15级[1]，导致预报难度大，致灾性强。2024年5月30日北京强对流天气就是典型案例，当时树木连根拔起、路面被顶开，强风达到13级以上[1]。
The China Meteorological Administration has issued a warning for severe convective weather across central and eastern Inner Mongolia, northeastern regions, and North China between August 4 and 6.[1] The forecast includes thunderstorms with winds of 8 level or stronger, with some areas potentially experiencing gusts exceeding 10 level intensity.[1]
Chief forecaster Fang Chong explained that the most dangerous phenomenon accompanying these storms is the "downburst"—an extreme weather event where wind speeds can reach 12 level or higher at the surface, potentially exceeding 15 level intensity.[1] Downbursts are characterized by their sudden onset, occurring over periods ranging from minutes to tens of minutes, and their localized impact area spanning from dozens of meters to several kilometers across.[1] These extreme weather events pose significant forecasting challenges due to their unpredictable nature and severe destructive potential.[1] A case in point occurred on May 30, 2024, when severe convective weather struck Beijing, uprooting trees completely, buckling road surfaces, and generating winds exceeding 13 level intensity.[1]
