Read the para under the title “Effects of Planetary Winds” and comment on it.Effects of Planetary Winds: You would have noted that the pressure and wind systems are actually a result of the impact of Lithosphere and Hydrosphere on Atmosphere. These winds play a crucial role in transporting heat and moisture across the world. That is why no part of the world gets too cold or too hot for life to survive.Had there been no atmosphere (as on the Moon) it would have got intolerably hot in day time or in the tropics and intolerably cold at night or in the Polar regions. However, these winds do not distribute heat or moisture uniformly – which is why we have some parts of the earth quite hot, some parts cooler and some parts with high rainfall and some which are deserts.

Answer»

Planetary winds are winds that are created in the different Global circulation cells. 

1. Polar Easterlies – blow from pole to 60° 

2. Prevailing Westerlies – blow from 60° to 30° 

3. Trade Winds – blow from 30° to 0° 

These winds transport heat and moisture across the world. But the winds do not distribute heat or moisture uniformly.
