Calculate the 1000-500 mb thickness if the height 534 dam; Thickness is calculated by subtracting the 1000mb height (185m) from the 500mb height
of the 1000mb surface is 185m and the height of (5525m). You then need to convert from meters to deca-meters to get the correct value.
the 500 mb surface is 5525m.
When more air mass is leaving a location than Divergence
entering, we refer to this as:
a. convergence
b. divergence
c. flatulance
The polar jet would have the best chance of being Winter; The jet outlines the temperature gradient. In the winter, the cold continental polar air
located over Florida during what season? plunges much farther south causing the sharp boundary between the continental polar air and
the maritime tropical air to move farther south. Thermal wind tells us the jet will lie above the
a. winter location where there is a sharp horizontal temperature gradient.
b. summer

, When examining an upper-level map, the polar jet Temperature (or thickness) pattern; The thermal pattern tends to outline the polar jet pattern
tends to be outlined by the: because this is where thickness/temperature change rapidly with distance in the horizontal.
a. Temperature pattern
b. Humidity (or moisture) pattern
c. Surface pressure pattern
d. Cloud pattern
Which force is significant only near the surface Friction (drag)
and disrupts geostrophic balance causing the
wind to blow across the isobars towards lower
pressure?
a. pressure gradient
b. centrifugal
c. Coriolis
d. friction (drag)
Friction at the surface of a low pressure system converge into the low creating upward vertical motion; Friction causes the surface air to cross the
causes winds to slow and: isobars towards lower pressure. This causes the air to converge (or "pile up") at the center of the
low resulting in upward vertical motion, since the air can't go into the ground.
a. converge into the low creating upward vertical
motion
b. diverge away from the low creating downward
vertical motion (subsidence)
c. neither converge nor diverge
The 1000-500mb thickness at location A is 540 B, The greater the thickness, the greater the average temperature of the layer between 500 and
dam, while the thickness at location B is 552 dam, 1000mb.
while the thickness at location C is 534 dam, which
location has the greatest average temperature in
the layer between 1000 and 500 mb?
a. A
b. B
c. C
Winds tend to change greatest with height over changes quickly over a relatively short distance; Thermal wind tells us the winds will change the
locations where the thickness: greatest with height above locations where the temperature (or thickness) changes rapidly in the
horizontal direction.
a. changes quickly over a relatively short distance
b. changes slowly over a very long distance
WXwith
c. remains nearly uniform 301distance
