Convection cloud systems

Abstract

The interaction of rising and environmental air is considered to be the main reason of the life cycle of convectional circulations composed of early, mature and dissipating stage. Wind shear caused deformations of otherwise symmetrical circulations resulting in special Cu cloud forms. The effect of varying upper air moisture on the diurnal march of convective cloudiness is discussed. The mentioned features in suitable combinations often affect large areas and determine the development of certain convection cloud systems on the mezoscale or even on the synoptic scale. The distinction of isolated Cu or Cb cloud formations of convective waves and streets permits us a better understanding of nonfrontal weather developments and  of its more efficient use for cross-country flying.
