🌊 風暴潮

風暴造成的海平面上升。

風暴潮

風暴帶來的強風將海水推向海岸,導致海平面遠高於預期潮位。這種異常上升的海平面就是風暴潮。它通常是登陸颶風或強溫帶氣旋最具致命性的因素。

風暴潮的高度取決於風速、風暴規模、來襲角度以及海岸線和海底形狀。淺海陸棚和漏斗狀海灣會顯著增強風暴潮。風暴潮之上疊加的波浪會進一步加劇破壞。

風暴潮預報結合了模型預測和沿海水深測量數據。低窪地區的疏散令主要基於預期的風暴潮。 1900 年加爾維斯頓颶風等歷史事件以及近期發生的風暴都展現了這種災害的威力。

    Coastal planning has to account for this more than ever with rising sea levels.

    Lived through a hurricane where the surge was worse than the wind. Water came up faster than anyone expected.

    Is storm surge the same as a tsunami? I know they're different causes but the flooding looks similar.
