Unformatted text preview: 46 mph. [see question 2.] 11. The initiating force for horizontal atmospheric motions is (d) pressure gradient. 12. In gradient flow around a high pressure system, the force pointing in the same direction are (a) centrifugal and pressure gradient forces. 13. In the Northern Hemisphere, if you stand facing the wind, low pressure region is (e) to your right. 14. The gradient wind is only an approximation to the true wind pattern in the atmosphere because it neglects (b) frictional forces. 15. There is less turbulence in the atmosphere than in the troposphere (a) true. 16. The geostrophic wind is independent of altitude in atmosphere that is (b) baratropic. 17. Cyclonic flow in the Northern Hemisphere is clockwise (b) false. 18. In middle latitudes, westerly wind in the troposphere are (a) strengthened upward....
