Title:

Tropospheric Wave Response to Descending Decelerations in the Stratosphere

Time: 3:30 PM, Thursday, 02/12/04

Place: Guggenheim Room 408d

Abstract.

Previously it has been shown that the anomalies in the stratosphere can descend all the way down into the lower troposphere. This is seen through an analysis called Empirical Orthogonal Functions. However, the character of these anomalies in the stratosphere is different from those in the troposphere. These signal are approximately zonally symetric in the stratosphere and then acquire a wave component in the troposphere. I will present a simple theoretical calculation to show that the reaction in the troposphere is due to the changing medium in the stratosphere.
