Show Occluded Front: What Is It? What is an occluded front? What causes them to form? AN OCCLUDED front is always al-ways formed when a cold front (which travels up to 35 m.p.h. or sometimes even faster) overtakes the slower-moving slower-moving warm front. The cold air mass pushes the warm, often moist, air upward and there is a mixing process which may confuse the observer on the ground and even the professional in his forecasting office. A characteristic of an occluded front is heavy rain and often strong winds. Often, however, the cold front which overtakes the warm will speed up the eastward movement of weather and clearing will come sooner than had the warm front passed overhead in a normal manner. |
