True
Air mass is a volume of air with similar temperatures and humidity. It forms above its source region after days or weeks picking up its particular temperature and humidity. When it is blown over to a region with a different characteristic, it becomes a storm.
The statement is true as air masses form in areas of low winds.
An air mass is a huge volume of air in climate that is for the most part uniform in temperature and dampness.
Air masses structure over enormous surfaces with uniform temperatures and mugginess, called source locales. Low wind velocities let air stay stationary long enough to assume the highlights of the source locale, for example, warmth or cold.
At the point when winds move air masses, they convey their climate conditions (warmth or chilly, dry or sodden) from the source district to another locale. At the point when the air mass arrives at another area, it may conflict with another air mass that has an alternate temperature and mugginess. This can make an extreme tempest.
