1

Atmospheric Pressure

  • Atmospheric pressure is the weight of air on a unit area of Earth's surface.
  • It is measured using a barometer in units of millibars (mb).
  • Standard sea-level pressure is 1013.25 mb.
2

Pressure Belts of the World

  • There are seven global pressure belts: one equatorial low, two subtropical highs, two subpolar lows, and two polar highs.
  • Equatorial Low-Pressure Belt lies between 0° to 5° N and S; receives vertical sun rays, causing air to rise.
  • Subtropical High-Pressure Belts lie around 30° N and S; sinking air creates calm zones known as Horse Latitudes.
3

Winds and Their Types

  • Winds are horizontal movements of air from high to low pressure.
  • Permanent winds blow regularly throughout the year: Trade Winds, Westerlies, Polar Easterlies.
  • Trade Winds blow from subtropical highs (30°) to equatorial low (0°); called NE in Northern Hemisphere, SE in Southern Hemisphere.
