Role of Condensed Water in the Life Cycle of a Convective Cloud
Publisher: American Meteorological Society
Abstract: The effects of precipitation formation in convective clouds are studied numerically with the help of a one-dimensional steady-initial-state model of convection in a nonviscous adiabatic atmosphere, incorporating the negative ...
Influence of Wind Shear on the Growth of Hail
Publisher: American Meteorological Society
Abstract: Dessens (1960) has suggested that strong winds aloft favor the growth of hail in thunderstorms building under their influence. The physical implication of this suggestion is examined by making computations on the growth ...
A Non-Archimedean Approach to the Equations of Convection Dynamics
Publisher: American Meteorological Society
Abstract: A new formulation of the momentum equations in convection dynamics is presented, dividing the pressure into separate hydrostatic and dynamic components. In this formulation, termed non-Archimedean, convection is envisaged ...
Microphysical Implications of Precipitation Formation in an Adiabatic Vertical Current: Aerosol Scavenging by Enhanced Nucleation
Publisher: American Meteorological Society
Abstract: The time-dependent effect of precipitation formation and development on the dynamics and microphysics of adiabatic vertical motion has been studied with the help of one-dimensional numerical models. Since the most important ...
Effect of a Precipitation-Driven Downdraft on a Rotating Wind Field: A Possible Trigger Mechanism for Tornadoes?
Publisher: American Meteorological Society
Abstract: The Physical and dynamical effects of simulated precipitation in a rotating wind field are examined by numerical experiments. The physical-dynamical model consists of the three equations of motion, a thermodynamic equation, ...
