Warm Front
a front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather
A warm front is a transition zone where a mass of warm air replaces a mass of colder air over a region. Warm fronts typically occur when a warm air mass moves towards a region occupied by a cold air mass. During this transition, the warm air rises above the denser cold air, leading to the formation of clouds and precipitation.
Warm fronts are characterized by a gradual and slow-moving front, typically spanning hundreds of miles. As a warm front approaches an area, the temperature gradually begins to increase, and the pressure tends to drop. This is because the warm air rises above the colder air, creating a zone of low pressure at the surface.
As the warm front passes through an area, weather patterns such as cloudy skies, rain, and sometimes thunderstorms are commonly observed. The type of precipitation that occurs depends mainly on the temperature of the air mass being replaced. For example, if the cold air mass is cold enough, snow or freezing rain may occur.
In general, warm fronts are associated with a gradual increase in air temperature and humidity, and are known to cause less severe weather events than cold fronts. However, they can still bring about significant weather changes such as prolonged periods of rain, fog, or thunderstorms.
