Question

Identify the CORRECT statement about cyclones:
1. High speed winds circulate around a high pressure region 
2. The coastline of India is not vulnerable to cyclones
3. The wind direction is clockwise in southern hemisphere and anticlockwise in northern hemisphere
4. The wind direction is clockwise in both hemispheres 

Answer 1

Correct Answer - Option 3 : The wind direction is clockwise in southern hemisphere and anticlockwise in northern hemisphere

The Correct Answer is The wind direction is clockwise in the southern hemisphere and anticlockwise in the northern hemisphere.

 

• Cyclones are rapid inward air circulation around a low-pressure area. Hence option 1 is Not Correct.
• The air circulates in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere. Hence option 3 is Correct.
• Cyclones are usually accompanied by violent storms and bad weather.

 

• The word Cyclone is derived from the Greek word Cyclos meaning the coils of a snake.
• It was coined by Henry Peddington because the tropical storms in the Bay of Bengal and the Arabian Sea appear like coiled serpents of the sea.
• There are two types of cyclones:
  • Tropical cyclones
  • Extra-Tropical cyclones (also called Temperate cyclones or middle-latitude cyclones or Frontal cyclones or Wave Cyclones).
