When air masses meet. When a moving cold air mass meets a warm air mass, that is lighter, it tends to wedge below the latter, thus giving origin to a cold front. The warm air is forced upwards and its ascent causes the formation of clouds.
frontal wedging, when cool air acts as a barrier over which warmer, less dense air rises; (3) convergence, which happens when air Â´ows together and a general upward movement of air occurs; and (4) localized convective lifting, which occurs when unequal surface heating causes pockets of air to rise because of their buoyancy. The stability of air is determined by examining the temperature of the atmosphere at various altitudes.
