🔥 暖鋒

暖空氣上升到冷空氣之上的邊界。

當暖空氣推進並取代地表冷空氣時，形成的邊界就是暖鋒。暖空氣逐漸上升到密度較大的冷空氣之上，在暖鋒前方形成大片雲層和降水。

雲層的形成通常始於高卷雲，隨後雲層降低增厚，最終出現小到中雨。鋒面過境後，氣溫和露點升高，風向通常也會改變。暖鋒的坡度比冷鋒緩，因此天氣變化也更為漸進。

地圖上以紅色半圓標示暖鋒，半圓指向暖鋒的移動方向。暖鋒是中緯度氣旋的常見特徵，通常預示著風暴系統的到來。

I'm a pilot and warm fronts are a big deal for us. They bring gradual changes but can also mean low visibility.

My garden always perks up after a warm front moves through. The steady rain really soaks in.

So when a warm front passes, the temperature rises and the rain usually stops? Trying to get this straight.
