Numerical Experiments on the Stratospheric-Tropospheric Dynamical Interaction.

Abstract

Numerical experiments with the UCLA-NEPRF tropospheric weather forecast model were performed to test the influence of stratospheric conditions which are representative of sudden warmings on tropospheric weather. Stratospheric conditions were represented by imposed vertical velocities at the upper boundary. An externally forced stratospheric disturbance as large as a sudden warming was found to generate an observable response in sea level pressure with a time constant of the order of a day. The numerical results are interpreted with the aid of an analytical model based on the linearized shallow water equation.
