Question:
All high pressure centers usually form
A. Cyclones
B. Anticyclones
C. Horse latitudes
D. All the above
Answer:
The correct answer is B)
Explanation:
When the atmospheric pressure in a geographical area is greater than it's surrounding vicinity, the space with the high atmospheric pressure is usually referred to as an <em>anticyclone</em> area. Moving away from the above area in any direction, the readings will depict a low pressure.
Anticyclone is the opposite of a cyclone.
When the temperature of an air mass cools rapidly more than its surroundings, the air according to the laws of physics contracts. This contraction makes the air mass heavier. This heavy mass of air in that location resulting in increased surface air pressure in that area is what we call <em>Anticyclones</em>.
Meteorologists usually embrace high-pressure readings because it translates to good weather. When there is an anticyclone, the following are usually resultant effects: clear skies, cooler and drier air. Like everything, a prolonged anticyclone may eventually become detrimental leading to still air and the possibility of heatwaves.
