Question

Q. Consider the following:

Which of the following climatic phenomena would exhibit the above characteristics?

• A.
  Tropical Cyclone in Southern Hemisphere
• B.
  Anticyclone in Northern Hemisphere
• C.
  Anticyclone in Southern Hemisphere
• D.
  Tropical Cyclone in Northern Hemisphere

Answer 1

The correct option is A

Tropical Cyclone in Southern Hemisphere
Explanation:

The tropical cyclone winds rotate in anti or counter-clockwise in the northern hemisphere and clockwise in the southern hemisphere around the low pressure, because of the Coriolis Effect (which deflects the wind direction to the right side of the actual movement of the wind in the northern hemisphere and left side in the southern hemisphere) due to the earth’s rotation. When tropical cyclones approach there is a drop in pressure and there is a steep temperature gradient within the system.

Note: Anticyclone are high pressure systems. High pressure systems have small pressure gradients. So there will be no inward flow of winds rather there will be outward flow of wind.
