锋面雨 Precipitation types
（重定向自Frontal rain）
锋面雨(英语：frontal rain)，泛指各种锋面通过一个地区后带来的降雨。又称气旋雨、梅雨。
冷锋的降雨原理：在冷空气与暖空气的交界面，冷空气快速切入暖空气下方，迫使暖空气迅速爬升，遇冷凝结成雨（或雪）；暖锋的降雨原理：在冷暖空气交界面，冷空气开始撤离，暖空气则顺势缓缓爬升至冷空气上方，冷凝成雨； 静止锋的降雨原理：冷空气与暖空气势力相当，遂在交界处形成大范围的降雨带； 囚锢锋的降雨型态则较为复杂，端看属于哪种囚锢锋（冷锋型囚锢、暖锋型囚锢、中性囚锢）而定。
冷锋通常会在锋面通过后降雨，降雨时间较短（半天-2天），有时会出现强度较强的暴雨或雷雨；暖锋则通常在锋面前方降雨，降雨时间略长（可能延续数天）；静止锋（滞留锋）的降雨常可持续多日、甚至达两周左右，有时细雨霏霏，有时伴随雷雨胞而带来强阵雨。

Precipitation types
In meteorology, "precipitation types" can include the character or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur. Convective precipitation is generally more intense, and of shorter duration, than stratiform precipitation. Orographic precipitation occurs when moist air is forced upwards over rising terrain, such as a mountain.
