Canada) Can produce cold fronts Warm, moist air mass Forms in South over water (ex. Caribbean or Florida) Can produce warm fronts and tropical storms Both fronts Both change the temp and weather in an area. Both can bring precipitation Cold air moves in and pushes warm air UP (quick) Can produce tall cumulonimbus clouds and Thunderstorms Air behind is cooler Warm air moves in and rides over cold air (slow) Can produce flat stratus clouds and steady rain
