2-10. Incoming   solar   radiation   is   greatest   at   the equator and least at the poles. What affect, if any, does this have on the atmospheric pressure in these areas? 1. Pressure is high in both areas 2. Pressure is higher at the poles than at the equator 3. Pressure  is  lower  at  the  poles  than  at  the equator 4. Incoming  solar  radiation  has  no  effect  on pressure in these locations 2-11. If  Earth  did  not  rotate  and  its  surface  was uniform,   in   the   Northern   Hemisphere   its surface winds would blow in what direction? 1. West to east 2. East to west 3. North to south 4. South to north 2-12. Coriolis force is an apparent force created by 1. temperature  variations  between  the  poles and equator 2. the tilt of the Earth’s axis 3. the Earth’s rotation 4. pressure  variation  between  the  poles  and equator 2-13. How    does    Coriolis    force    affect    moving objects? 1. It  produces  positive  temperature  changes on them 2. It lessens the pressure gradient on them 3. It increases and decreases their speed 4. It   forces   objects   to   the   right   of   their intended path in the Northern Hemisphere 2-14. The three cells of the tri-cellular theory are the 1. tropical, subtropical, and polar 2. equatorial, subtropical, and polar 3. tropical, midlatitude, and polar 4. equatorial, midlatitude, and polar 2-15. The  surface  wind  generated  by  the  Earth’s general circulation pattern is 1. westerly at all latitudes 2. northeasterly  in  the  tropics  and  poleward of 60°N/S and westerly in the midlatitudes 3. northwesterly in the tropics and poleward of 60°N/S and westerly in the midlatitudes 4. northwesterly poleward of 60°N/S, northeasterly    in    the    midlatitudes    and easterly in the tropics 2-16. Which of the following regions feature(s) light and variable winds? 1. The doldrums 2. The horse latitudes 3. The regions near 30°N and 30°S 4. All of the above 2-17. What  force  moves  air  in  a  straight  line  from areas of high pressure to areas of low pressure? 1. Friction 2. Centrifugal 3. Pressure gradient 4. Coriolis 2-18. What   is   inferred   from   horizontal   pressure gradients classified as flat or weak? 1. Isobars are closely spaced 2. Isobars are widely spaced 3. The winds are light 4. Both 2 and 3 above are correct 2-19. The    latest    upper-air    sounding    shows    the 1000-700   mb   layer   over   your   station   has decreased in thickness over the last 24 hours. What does this change in thickness tell you, if anything,  about  the  vertical  pressure  gradient within this stratum? 1. It has increased 2. It has decreased 3. The  gradient  remains  unchanged  because the pressures have not changed 4. Nothing without height figures 2-20. Which of the following forces has the greatest effect on wind speed? 1. Centrifugal 2. Pressure gradient 3. Friction 4. Coriolis 2-21. Which of the following forces causes the wind to  begin  moving  from  areas  of  high  pressure toward areas of low pressure? 1. Centrifugal 2. Pressure gradient 3. Friction 4. Coriolis 8
