Question

Compare and contrast HIGH versus LOW pressure systems. Refer to the following

A) Air movement at the surface (is it inward or outward - DO NOT worry about what is happening
ALOFT)
B) Air movement vertically (is the air at the center rising or falling)
C) Thus is the moving air expanding or compressing? and thus what is temperature change of
vertically moving air?
D) Finally, what is the resulting Sky condition associated with each
E) And WHY do you expect those sky conditions?

Answer 1

This answer compares and contrasts HIGH and LOW pressure systems regarding air movement, temperature change, sky conditions, and the reasons behind those conditions.

Step-by-step explanation:

The Comparison between HIGH and LOW Pressure Systems:

A) Air movement at the surface: In a HIGH pressure system, air moves outward from the center, while in a LOW pressure system, air moves inward towards the center.

B) Air movement vertically: In a HIGH pressure system, the air at the center is sinking or falling, whereas in a LOW pressure system, the air at the center is rising.

C) Expanding or compressing air: In a HIGH pressure system, the moving air is compressing, leading to an increase in temperature. In contrast, in a LOW pressure system, the moving air is expanding, resulting in a decrease in temperature.

D) Sky conditions associated with each: A HIGH pressure system is usually associated with clear and fair weather conditions. On the other hand, a LOW pressure system often brings cloudy skies and potentially stormy weather.

E) The reason behind these sky conditions: In a HIGH pressure system, the sinking air suppresses cloud formation, leading to clear skies. In a LOW pressure system, the rising air and increased moisture create cloudy conditions and precipitation.
