Write note on:Horizontal distribution of air pressure.

Answer»
  • The heat received from the sun is uneven in different regions.
  • The distribution of temperature is uneven from the equator to the poles.
  • This difference can lead to difference in air pressure.
  • There are four air pressure belts formed on the earth surface.
  • Equatorial low-pressure belt between 5°N and 5°S parallels as the temperature is high here.
  • Mid latitudinal high-pressure belt between 25° and 35° parallels due to descending heavier air.
  • Subpolar low-pressure belt formed between 55° and 65° parallels due to friction and rotation.
  • Polar high-pressure belt formed between 80° and 90° parallels due to low temperatures.
