1
question 3 How will the 700 mb height in the southern half of Indiana evolve according to Fig. 1? Explain, using QG theory.
2
updraft height fall next 6 hrs from 2820 to 2790 m C
3
C height fall last 6 hrs
4
question 4 Should there be rising or sinking motion at the level shown in Fig. 2, in Ohio? Explain, using QG theory.
5
CAA CVA CAA CVA
6
differential CVA over Ohio rising motion? CAA over Ohio sinking motion? Two forcing terms oppose & partially cancel each other in Ohio Net rising motion in this case

question 5 a)(2%) Draw one major trough line (blue). b)(4%) Place red arrows on appropriate isolines to indicate the direction of the 600-400 hPa thermal wind. (no need to do this over the entire map; just focus on Colorado & vicinity) c)(4%) Also place blue arrows between appropriate lines to indicate the direction and speed of the 500 hPa geostrophic wind. d)(5%) Mark the location of strongest WAA and strongest CAA at 500 hPa with the initials WAA and CAA. e)(5%) Using the omega equation (temperature advection “forcing” only), write a U and D (blue) for centers of ascent & descent, resp., at 500 hPa. f)(5%) Indicate the location of maximum geostrophic vorticity at 500 hPa with a red cross. g)(5%) Using the omega equation (vorticity advection “forcing” only), write a U and D (red) for centers of ascent & descent, resp., at 500 hPa. h)(5%) Draw Q vectors at all intersections of red and black lines (isotherms and gph contours) in the states of Montana, WY, CO, ND, SD, KA, and OK. From these vectors, identify regions of Q convergence/divergence, and thus rising/sinking motion. i)(5%) Compare the three estimates of rising/sinking motion (TA, VA, and div Q), and explain any differences. j)(extra 5%) Locate the sea level low (L) and high (H) associated with the trof over the western US
