Question

The part/parts of a tropical cyclone, which is/are called the strongest winds, tallest clouds & heaviest rains, are-

1. Eyewall
2. Warm core

1. Only I
2. Only II
3. Both I & II
4. None I & II

Answer 1

Correct Answer - Option 1 : Only I

• The correct answer is Option(1) i.e. Only I.
• Eyewall, part of a tropical cyclone is called the strongest winds, tallest clouds, and heaviest rains.
• Eyewall:  
  • Around the eye of cyclones is the eyewall, in which there is a solid spiraling rise of air to a height that reaching the ultimate limit is called the tropopause.
  • The wind reaches in his maximum velocity in that particular region and also torrential rain occurs here.
  • From the eyewall, The bands of rain may radiate, and also trains of cumulus and cumulonimbus clouds may drift into the outer region. 
• Eye of Cyclone: 
  • A mature tropical cyclone is featured by the solid spirally circulating wind around the center which is called the eye of the cyclone. 
  • The eye is that particular area with calm weather descending air.
  • It is featured by clear skies & light winds. 
• Conditions for the formation of Tropical Cyclone: The conditions which favor the intensification & formation of a tropical cyclone are as follows: 
  • ​Large sea surface with a temperature greater than 27° C.
  • Presence of the Coriolis force.
  • A little difference in the wind speed which flows vertically.
  • Existing of the weak- low-pressure area or low-level-cyclonic circulation.
  • Upper divergence above the sea level.
