The planetary winds blowing between the tropics are known as trade winds. They are found in the lower section of the troposphere near the earth’s equator. Trade winds blow predominantly from the north-east in the Northern Hemisphere and from the south-east in the Southern Hemisphere. More rainfall can be expected within neighbouring landmasses if the trade winds become weaker.

• A tornado is a violent rotating column of air extending from a thunderstorm to the ground. 
  
• The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph.
  
• They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards.
  

True,

In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole. As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude. The descending air blows from the northeast to the southwest, back toward the equator. Similarly, in the Southern Hemisphere, these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude. If the direction of rotation changes the pattern will be a mirror image of the original, hence the Trade Wind in the southern hemisphere will blow from South West towards the equator.

Four States (Andhra Pradesh, Odisha, Tamil Nadu and West Bengal) and one UT (Pondicherry) on the East Coast and One State (Gujarat) on the West Coast are more vulnerable to cyclone disasters.

The planetary winds which blows between the tropics are termed as trade wind. Trade wind move out from the sub tropical high-pressure belt towards equators. In different sections of their path, the condition of temperature, humidity, and density is not uniform.
