GENESIS OF MESOSCALE CONVECTIVE SYSTEMS ABOVE UNEVEN SOIL MOISTURE CONDITIONS

Heterogeneities in vegetation type, soil type, or soil moisture can induce physiographically forced mesoscale circulations through sensible heat flux gradients at the surface. These mesoscale circulations can provide regions of convergence, triggering deep convection. Here, Cheng and Cotton examine...

Zusammenfassung:Heterogeneities in vegetation type, soil type, or soil moisture can induce physiographically forced mesoscale circulations through sensible heat flux gradients at the surface. These mesoscale circulations can provide regions of convergence, triggering deep convection. Here, Cheng and Cotton examine the sensitivity of a simulation of the genesis of a mesoscale convective system to the initial soil moisture distribution.
