Please help with this homework weather question...!?

Question

I am doing this assignment and am stuck on this question. Any help would be much appreciated!

Q- Considering that low pressure and high pressure zones give us different weather patterns, compare their air flow directions at ground level and aloft and explain how this flow contributes to the weather pattern.

Answer 1

In the northern hemisphere high pressure rotates clockwise and is associated with fair weather while low pressure rotates counter-clockwise and is associated with stormy weather. The high pressure air is more dense and sinks while the low pressure air rises which causes the formation of clouds and the storms.
In the southern hemisphere the rotations are opposite but same priciple.

Answer 2

At ground level, the air moves from the high pressure to the low. Near the tropopause (about 35,000 feet high) the air moves from the low pressure to the high pressure, but slower that on the ground. The reason is: in a low pressure the air rises thus creating a vacuum that fills from under. In a high pressure, the air sinks, thus taking air from the top.
As air rises or sinks, it is subject to adiabatic cooling or warming. This is the same principle you find in your refrigerator: increase of pressure generates heat. Release the pressure absorbs heat.
In the low pressure, the rising and cooling air condenses humidity as clouds. In a high pressure, the sinking and heating of air dissipates humidity and the sky is clear.

Answer 3

Think about the pressure difference in the atmosphere... does pressure increase or decrease with amplitude?

Pressure decreases with amplitude... you should be able to answer your question now.
