🔥 暖锋

暖空气上升到冷空气之上的边界。

当暖空气推进并取代地表冷空气时，形成的边界就是暖锋。暖空气逐渐上升到密度较大的冷空气之上，在暖锋前方形成大片云层和降水。

云层的形成通常始于高卷云，随后云层降低增厚，最终出现小到中雨。锋面过境后，气温和露点升高，风向通常也会发生变化。暖锋的坡度比冷锋缓，因此天气变化也更为渐进。

地图上用红色半圆标示暖锋，半圆指向暖锋的移动方向。暖锋是中纬度气旋的常见特征，通常预示着风暴系统的到来。

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.
