#6
The figure above shows a 500 mb weather map. Let’s assume the atmosphere is in geostrophic balance at the location of the star. Draw the pressure gradient force, the Coriolis force, and the resultant geostrophic wind.
#7
True/False: The jet stream is westerly in the northern hemisphere and easterly in the southern hemisphere.
#8
True or False: Surface low pressure systems are associated with surface convergence and rising motion.
PGF points towards the southeast, CF points towards the northwest, the wind is northeasterly D Question 6 5340 5400 546 5340 540646 80 57 5820Explanation / Answer
Question 6: PGF points towards northwest and CF points towards south east, thewind is southwesterly.
Question 7: False
Because we can observe both easterlies and westerlies in Northern hemisphere and Southern hemisphere depends on latitude as shown below.
Winds in between major pressure regions (so latitudes are approximate):
0°- 30° N = NE Tradewinds
0°- 30° S = SE Tradewinds
30° - 60° N and S = Westerlies
60° - 90° N and S = Polar Easterlies
Question 8: True
Surface low pressure areas are associated with surface convergence, forced rising air, and a good possiblity for clouds and precipitation.
