An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere —16 kilometers (10 miles) into the atmosphere.

TYPES OF AIR MASSES . On the basis of latitudinal position five types of air masses are distinguished as shown below - [ c = continent, m = maritime, P= polar, T= tropical, E=equatorial, A=arctic, AA=Antractic ] Based on thermodynamics and mechanical modification and some other considerations air masses are divided into 16 types as follows-

a huge body of air that has similar temperature, humidity, and air pressure at any given height. tropical air mass. warm air masses that form in the tropics and have low pressure. continental air mass. dry air masses that form over land.

The weather an air mass brings is determined by the region it has come from and the type of surface it has moved over. An air mass is a large body of air, whose properties – temperature, humidity (air moisture) and lapse rate – are largely uniform (the same) over an area several hundred kilometers across. The regions where air masses form are referred to as air mass source regions. Air masses are classified into groups depending on their basic temperature and humidity characteristics. There are six main types of air masses that affect the British Isles. We classify these air The air mass coefficient defines the direct optical path length through the Earth's atmosphere, expressed as a ratio relative to the path length vertically upwards, i.e. at the zenith.

As air masses move around the Earth due to weather conditions, they can gain or lose moisture, or increase or decrease in temperature. For example, a maritime polar (mP) air mass moving across a continent could lose much of its moisture and become a continental polar (cP) air mass.

An air mass is a large body of air, whose properties – temperature, humidity (air moisture) and lapse rate – are largely uniform (the same) over an area several hundred kilometers across. The regions where air masses form are referred to as air mass source regions.

Air Masses form where there is persistant atmospheric conditions. This is primarily where the upper air is dominated by anticyclones. In regions where cyclone dominate the air near the surface is constantly changes as air is brought into the region from Semi-permanent high pressure systems determine migration of the air masses during the summer and winter months.

When air masses move from the areas they form in, to other 25 Apr 2020 temperature, pressure and moisture. A good source region for the air mass to develop should be: a fairly uniform extensive area. Extremely cold, dry, stable airmass. (coldest wintertime airmasses). Produce intense cold waves. No clouds in these air masses.
