Document Summary
A front is the line between a cold air mass and a warm air mass. Since cold air is denser than the warm air it can act like a barrier that forces warm upward. As the warm air rises it cools to the dew point temperature and forms clouds. More it rises, the more it cools and the more likely precipitation is. This type of lifting is responsible for the majority of precipitation in the. Last way air is forces to rise is convergence. Air on the surface moves in complicated patterns and sometimes air can flow together. When this convergence, or meeting, of air occurs it must rise bc there is no where else for it to go. This also occurs when air flows from a smooth surface to a rough surface (water to land, plains to mountains, etc. ) The air must slow down over the rougher terrain so it piles on top of itself.
