This document contains a multi-part question about an upper-level jet streak in the Northern Hemisphere. It asks the reader to: 1) label regions of upper-level divergence and convergence on a diagram of the jet streak and indicate expected rising or sinking motion below each area; 2) explain physically why the entrance region has the vertical motion drawn in part a; and 3) sketch the circulation in the vertical plane of the jet entrance region by drawing height surfaces and arrows.

1. Can you please answer and explain every part of the question? Please draw the diagram as well.
thank you xercise 10: Consider a west-to-east oriented upper tropospheric jet streak consisting of
westerly winds in the Northern Hemisphere. a) In the diagram below, an upper-level jet streak
with lines of constant wind (isotachs) is shown; the arrow represents the strongest winds at the
center. Label the regions of upperlevel divergence and convergence (in both the entrance and
exit regions). Also indicate whether you would expect rising motion (w>0) or sinking motion
(w<0) in the atmospheric column below these areas. b) Why does the entrance region have the
vertical motion that you drew above? Be concise yet complete; I expect a response involving
physical explanations and justifications. c) Using the figure below, sketch a vertical plane of the
jet entrance region (xz plane, with A extending to B on the x-axis). Draw two horizontal lines
showing upper- and lowerlevel height surfaces indicating the upper- and lower-level planes.
Indicate with arrows the circulation that develops in this vertical plane.
