In-class Exercise 4
On a given day, a trough in the westerlies is progressing across the United States. At the inflection point on the eastern side of the trough, the net divergence in the layer from the LND to the tropopause was 2.78 X 10 –5 s -1. The LND was at the 500 mb level an, on this day, the Tropopause was approximately located at the 300 mb level. Also, at the inflection point, the 500 mb height was 546 dm and the 300 mb height was 943 dm.
Determine the vertical velocity at the LND in cm s-1.
