The migration of air masses from their source must result eventually in their meeting and interference and this will occur in regions of low pressure, which by their very nature must be regions of convergence. Experience shows that although there is inevitably some marginal mixing and incorporation, the air masses tend to retain their individual characteristics fairly clearly defined, especially in the upper air, which is less disturbed by the turbulence that affects the lower strata in contact with the earth’s surface. The convergence results in the displacement from the surface of the lighter and warmer air, by the denser and colder air and this ascent produce condensation and precipitation. The severity of the disturbance that accompanies this convergence is proportional to the contrast of temperature and humidity of the air masses involved, for the temperature contrasts provide the main source of energy for the generation of storms. Storminess is greatest where polar air meets tropical, as it does along the polar fronts and much less where tropical meets tropical along the equatorial front.
