Essay On Frontal Precipitation

What is Frontal Precipitation?

Frontal precipitation occurs along fronts. It is formed once two air masses of diverse temperature; humidity and density meet such as the meeting of polar air mass and a tropical maritime air mass. A zone called a front separates them. When warm, moist air mass meets a cool and dry air mass and because the molecules of cold air are more tightly packed together making it denser, the warm air is forced to go up and over the cool air mass. As the warm air mass rises, the water vapour in the air condenses, and the clouds and precipitation occurs. Frontal precipitation is also called cyclonic precipitation.

Do any of the LOWERN factors cause frontal precipitation?

Most of the LOWERN factors have something to do with frontal precipitation.

The first factor is latitude; Latitude is how far north or south you are located from the equator which means that the farther you are from the equator, the colder the climate is. Basically there will be colder air masses which mean that if they collide with any warm air masses, it will cause frontal precipitation. Also frontal precipitation occurs mostly around mid-latitude regions where warm tropical air meets cold polar air.

Ocean currents;

These air masses being carried by wind extend to about hundreds and thousands of kilometres. This is where frontal precipitation occurs. In the summer the cold, dry continental arctic cool winds originates towards south bringing a respite of heat waves which collides with the maritime arctic air mass which travels over large bodies of water making it moist and mild. When these two air masses collide, the formation of frontal precipitation occurs and causes rain. In the Maritimes, most precipitation is caused when cold dry air from the north meets warm, moist air from the
