Question

a) What is meant by term 'Atmospheric pressure'?
b) What is Coriollis Effect? How does it affect the planetary winds?​

Answer 1

1. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.
2. The Coriolis effect helps determine the direction of planetary, or global, winds by causing them to curve, or deflect, as the Earth rotates. In the Northern Hemisphere, winds curve to the right in the direction of motion. ... The difference in temperature between land and sea also influences global winds.
