ASSIGNMENT 1 Textbook  Assignment: “Convergence,  Divergence,  and  Vorticity,”    “Forecasting  Upper  Air Systems,”  and   “Forecasting  Surface  Systems.” Pages 1-1 through 3-10. 1-1. Maximum  convergence  and  divergence occurs  between  what  levels  aloft? 1. 850- to 700-hPa levels 2. 700- to 500-hPa levels 3. 500- to 300-hPa levels 4. 300- to 200-hPa levels Figure  1-A IN ANSWERING QUESTION 1-2, REFER TO FIGURE 1-A. 1-2. The  wind  symbols  and  streamlines  in Figure  1-A  depict  what  information? 1. Speed  divergence  and directional   divergence 2. Speed  convergence  and directional   divergence 3. Speed  divergence  and directional   convergence 4. Speed  convergence  and directional 1-3. The  “advection” regarded as the specific  level? 1. The  200-hPa 2. The  300-hPa 3. The  400-hPa 4. The  500-hPa convergence stratum may be stratum below what level level level level 1-4. If all other motions of convergence and divergence are neglected, rising and falling heights at the isopycnic level are the result of what  actions? 1. 2. 3. 4. Rising heights are due to subsidence, and  falling  heights are  due  to  convection Rising heights are due to convection, and  falling  heights are due to subsidence Rising heights are due to divergence  above  the  isopycnic level,    and  falling  heights  are due  to  convergence  above  the isopycnic  level Rising  heights  are  due  to convergence  above  the  isopycnic level,    and  falling  heights  are due to divergence above the isopycnic  level 1-5. The  level  of  maximum  velocity convergence, located  between  the 300- and 200-hPa levels, is the primary cause of which of the following  conditions? 1. Pressure  rises  at  the  surface 2. pressure falls at the surface 3. Height rises in the upper troposphere  and  lower stratosphere 4. Height falls in the upper troposphere  and  lower stratosphere 1-6. Assume  that  the  vertical  motion  is upward and is a result of low-level convergence. This is indicative of what  type  of  circulation? 1. Lower  vertical  circulation  in an  anticyclone 2. Upper  vertical  circulation  in an  anticyclone 3. Lower  vertical  circulation  in advance of a low 4. Upper  vertical  circulation  in advance of a low 1-7. Maximum  horizontal  divergence occurs  at  approximately  what pressure  level? 1. The 500-hPa level 2. The  400-hPa  level 3. The  300-hPa  level 4. The 150-hPa level 1
