IN ANSWERING QUESTION 1-17, REFER TO FIGURE 1-4 IN YOUR TRAMAN. 1-17. In  evaluating  relative  vorticity from the shear effect alone on straight  contours  in  the  northern hemisphere, which  evaluations  of relative  vorticity  should  you  make? 1. Parcel  No.    1 has anticyclonic or  negative  vorticity;  Parcel No.    2 has cyclonic or positive vorticity; Parcel No. 3 has zero  vorticity 2. Parcel  No.    1 has zero vorticity; Parcel No. 2 has anticyclonic  or  negative vorticity; Parcel No. 3 has cyclonic  or  positive  vorticity 3. Parcel No. 1 has cyclonic or positive vorticity; Parcel No. 2 has anticyclonic or negative vorticity;    Parcel No. 3 has zero  vorticity 4. Parcel No. 1 has zero vorticity; Parcel No. 2 has cyclonic or positive vorticity; Parcel No. 3 has anticyclonic or  negative  vorticity IN ANSWERING QUESTION 1-18, REFER TO FIGURE 1-5 IN YOUR TRAMAN. 1-18. When you are considering the curvature effect alone for an evaluation  of  relative  vorticity, point P is considered to be a point of NO curvature and, therefore, zero  vorticity. What is another name for this point of NO curvature? 1. Mid-point  of  vorticity 2. Point  of  negative  vorticity 3. Point  of  positive  vorticity 4. Inflection  point IN ANSWERING QUESTION 1-19, REFER TO FIGURE 1-9 IN YOUR TRAMAN. 1-19. If only the curvature effect were considered, the  relative  vorticity would increase in which of the following  regions? 1-20. When  relative  vorticity  is decreasing  downstream  in  the  upper troposphere, what should you expect to  occur? 1. Convergence  aloft  and  surface pressure  falls 2. Decreased  precipitation  if sufficient  moisture  was initially  present 3. Decreased  thicknesses  between standard  isobaric  surfaces  in the  region  of  decreasing relative  vorticity 4. Divergence  aloft  and  surface pressure  falls 1-21. Long  waves  of  relatively  short wavelength, well-defined  major troughs and ridges, and well- developed  surface  cyclones  and anticyclones  are  associated  with which of the following wave patterns? 1. Changing  long-wave  patterns 2. Retrogression  of  long  waves 3. Progressive  long  waves 4. Stationary  long  waves 1-22. Which  of  the  following  conditions would NOT be an indication of the retrogression of a long wave? 1. Increased  cold  air  advection  in the  upstream  ridge 2. 24-hr  height  change trajectories  do  not  correspond to the band of maximum winds 3. New  height  centers  appear 4. Surface lows to the west of the major  trough  position  deepen 1-23. Which  of  the  following  statements is  generally  valid  when  poleward moving jet streams move into the upper  midlatitudes? 1. The amplitudes of the long waves  decrease 2. Low  zonal  indexes  are  reversed 3. The number of long waves increases 4. Associated  long  waves  speed  up 1. Regions I and II 2. Regions I and IV 3. Regions II and III 4. Regions III and IV 3
