| Using a three-dimensional cloud-resolving model, the present work demonstrates that convective storm motions are affected by thermodynamic as well as kinematic properties of the atmosphere. In addition to the mean wind, simulated storm motions are influenced by bulk convective available potential energy (CAPE); the vertical distribution of buoyancy in the profile; the heights of the lifting condensation level (LCL) and level of free convection (LFC); and cloud-base temperature. The vertical distribution of shear affects storm evolution and propagation, even when the bulk properties of the shear profile are unchanged. The results point to the importance of environmental factors that enhance storm intensity and rotation, which play a key role in determining storm deviate motion. |
