Winds within the base of a trough tend to be: - correct answer Sub-geostrophic
Which force is significant only near the surface and disrupts geostrophic balance causing the wind to blow across the isobars towards lower pressure? - correct answer ...
Winds within the base of a trough tend to be: - correct answer Sub-geostrophic
Which force is significant only near the surface and disrupts geostrophic balance causing the wind to
blow across the isobars towards lower pressure? - correct answer Friction (Drag)
Calculate the 1000-500 mb thickness if the height of the 1000mb surface is 185m and the height of the
500 mb surface is 5525m. - correct answer 534 dam
Thickness is calculated by subtracting the 1000mb height (185m) from the 500mb height (5525m). You
then need to convert from meters to deca-meters to get the correct value.
The 1000-500mb thickness at location A is 540 dam, while the thickness at location B is 552 dam, while
the thickness at location C is 534 dam, which location has the greatest average temperature in the layer
between 1000 and 500 mb? - correct answer B
The greater the thickness, the greater the average temperature of the layer between 500 and 1000mb.
Winds tend to change greatest with height over locations where the thickness: - correct answer
Changes quickly over a relatively short distance.
Thermal wind tells us the winds will change the greatest with height above locations where the
temperature (or thickness) changes rapidly in the horizontal direction.
When examining an upper-level map, the polar jet tends to be outlined by the: - correct answer
Temperature (or thickness) pattern
Above is a 500mb trough ridge pattern. Arrows indicate the wind speed and direction through the
trough with larger arrows indicating faster speeds. At which position (A, B, or C) would you expect more
air mass leaving the location than entering? - correct answer C
