A warm air occlusion or occluded front is less common than a cold occlusion. A warm occlusion occurs as cool air moves rapidly into an area with an existing warm front. The difference from a cold occlusion is that the approaching cool air is not as cold as the retreating cold air in the existing front. In other words, the fast-moving, incoming air is cold, but not as cold as the air mass ahead of it. Precipitation can usually be expected when an occluded front passes through an area. Sometimes a cold front will catch up to a warm front and overtake both it and the cooler air out ahead of it. If this happens, an occluded front is born.
To stop sweating and fog in the back half of a tunnel house during brooding, quit pulling all the air to the back and exhaust some air from a side wall or front wall fan in the brood chamber. This reduces the amount of moist air going through the back of the house.
