Research Abstract
Numerical simulations of cloud convection in Jovian planets are performed. A prominent feature is that intense moist convections occur intermittently even in the parameter range where convection inhibition has been estimated based on thermodynamic consideration. The intense convective activities are organized like "squall lines" in the earth's atmosphere. That is, evaporation of rain falling from the upper clouds drives downward flow, which is braked around the stable layer at the condensation or chemical reaction level and forms a strong horizontal "cold air outflow". At the front of the outflow, intense horizontal convergence triggers new convective clouds overcoming the negative buoyancy due to the large mixing ratio of condensable species. In this series of cloud developments, the statically stable condensation or chemical reaction level acts like "ground surface" for the Earth's squall lines.
