1-8. What is the result of stratospheric flow over a developing cyclone? 1. Downward  vertical  motion,  and convergence at the level of maximum  horizontal  divergence 2. Upward  vertical  motion,  and divergence at the level of maximum  horizontal  divergence 3. Upward  vertical  motion,  and convergence at the level of maximum  horizontal  divergence 4. Downward  vertical  motion,  and divergence at the level of maximum  horizontal  divergence 1-9. You  are  looking  downstream  and  find that  high-speed  winds  are  moving towards  weak,    cyclonically  curved contours. What effect should this have  on  upper-level  heights? 1. Heights  should  decrease downstream to the left 2. Heights  should  decrease downstream  to  the  right 3. Heights  should  increase downstream to the left 4. Heights  should  increase downstream to the right 1-10. When  an  anticyclonic  circulation center is out of phase with its pressure  center,  what  movement(s) bring(s)  about  a  readjustment? 1. The  movement  of  the  circulation and  pressure  centers  toward each other 2. The  movement  of  the  circulation center  toward  the  pressure center 3. Both 1 and 2 above 4. The movement of the pressure center  toward  the  circulation center 1-11. You  encounter  a  well-developed ridge that has sharply curved anticyclonic  contours  with  a  deep trough a short distance downstream. What action should you expect to take place? 1. Deepening  and  reorientation  of a portion of the trough 2. The cutoff low to retrograde from its position and the trough to reorient 3. Dissipation of the low at the lower end of the trough, depending on the initial winds in the ridge to the west 4. Filling and reorientation of the trough 1-12. Under what condition does the greatest  overshooting  of  high-speed winds occur? 1. When high-speed winds in the ridge are more than twice the measured  geostrophic  winds 2. When  measured  geostrophic  winds in the ridge are more than twice  the  high-speed  winds  in the ridge 3. When  low-speed  winds  approach the west side of the anticyclonic  ridge 4. When  low-speed  winds  are located  in  the  southwesterly flow of the downstream ridge 1-13. Convergence on the western side of a downstream trough has what results? 1. Dynamic  heating 2. A  decrease  in  upper-level heights 3. An  increase  in  upper-level heights 4. A  decrease  in  moisture 1-14. Which  of  the  following  statements concerning  the  convection  process is  valid? 1. Air-mass  stability  is  increased by the process 2. Air-mass  stability  is  decreased by the process 3. The air mass is compressed 4. Stratiform  type  clouds predominate in areas of convection 1-15. Upward motion will always result in cloudiness. 1. True 2. False 1-16. When  relative  vorticity  is evaluated, which  of  the  following components  of  rotational  motion should be considered? 1. Wind  shear  and  streamline curvature 2. Wind  shear  and  atmospheric rotation 3. Streamline  curvature  and atmospheric  rotation 4. Atmospheric  rotation  and cyclostrophic  motion 2
