Describe the evolution of the jet east of the trough over time. Discuss the role thermal wind may have had in contributing to the increase of the strength of this jet. Create a map of 300 mb heights and isotachs, and a second map of 850 mb heights and temperatures for the 18 UTC 17 Oct to give some perspective to the vertical cross sections. Create a third cross section along 92W from 42N to 55N for 12 UTC 17 October 96. If present, state type of front and sketch it's location on the cross section up to about 700 mb.
Negative values mean lowering heights and positive values mean rising heights.
The divergence of q will have units of order e-17 and are shaded where red colors mean upward motion and blue colors are downward motion. The model field is omega so that negative values mean upward motion and positive values downward motion. If there are any regions where the divergence of Q does NOT explain the cloud features, give two or three reasons why this might be the case.
