Abstract

Actual values of wind speed and pressure deficit of tornado and tornado-like vortices usually does not match the theoretical ones. To resolve the difference between the values obtained from observations and theory, the subsidence warming in the vortex core has been considered as a mechanism. This research provides the quantitative bounds on the efficacy of subsidence warming in idealized tornado-like vortices. The axisymmetric formulation of the incompressible primitive equations of motion was the basis for the model being used. This subsidence warming has small effect on the pressure deficit compared to other physical mechanisms and it does not have a significant impact on increasing the maximum wind speed.
