An air mass is a big mass of air that has comparable characteristics of temperature and also humidity in ~ it. An air mass acquires these characteristics over an area of soil or water recognized as its source region. When the waiting mass sits over a an ar for numerous days, or longer, it picks up the distinctive temperature and humidity features of that region.

Air fixed Formation

Where an waiting mass obtain it’s attributes of temperature and also humidity is called the source region. Air masses are progressively pushed follow me by high-level winds, once an waiting mass moves over a brand-new region, it share its temperature and also humidity through that region. For this reason the temperature and humidity the a particular location depends partly on the attributes of the waiting mass the sits over it. Storms happen if the air mass and the an ar it moves end have various characteristics. Because that example, once a cooler air fixed moves end warmer ground, the bottom layer of air is heated. That air rises, creating clouds, rain, and sometimes thunderstorms. Just how would a moving air mass type an inversion? as soon as a warmer waiting mass travel over colder ground, the bottom great of air cools and, because of the high density, is trapped near the ground.

In general, cold waiting masses tend to flow toward the equator and warm wait masses often tend to circulation toward the poles. This brings warmth to cold areas and cools down areas that are warm. It is just one of the plenty of processes the act in the direction of balancing out the planet’s temperatures. Air masses are slowly pushed follow me by high-level winds. Once an air mass moves end a brand-new region, it shares its temperature and humidity through that region. For this reason the temperature and humidity that a certain location depends partly on the features of the wait mass that sits end it. Waiting masses space classified based upon their temperature and humidity characteristics. Listed below are examples of just how air masses are classified end North America.

Maritime tropical (mT): moist, warm air massContinental tropic (cT): dry, warm air massMaritime polar (mP): moist, cold air massContinental polar (cP): dry, cold wait mass

Storms happen if the air mass and the region it moves end have different characteristics. For example, as soon as a cooler air massive moves end warmer ground, the bottom layer of air is heated. That air rises, creating clouds, rain, and sometimes thunderstorms. Exactly how would a relocating air mass kind an inversion? once a warmer air mass travel over colder ground, the bottom great of wait cools and, since of that high density, is trapped close to the ground.

In general, cold air masses often tend to circulation toward the equator and also warm air masses often tend to circulation toward the poles. This brings heat to cold areas and cools down locations that space warm. It is among the numerous processes the act towards balancing the end the planet’s temperatures.
