Consider the following characteristics of a tropical cyclone :

  • 1. A warm sea temperature of > 26°C
  • 2. High relative humidity of atmosphere at a height of > 700 m
  • 3. Atmospheric instability

The above mentioned characteristics are associated with which one of the following cycles of its development ?

Formulation and initial stage
Modification stage
Full maturity
Decay

The characteristics listed are the essential pre-conditions required for the initial formation and development of a tropical cyclone. These include sufficient warm sea surface temperature, high humidity, and atmospheric instability which fuel the convection and low pressure development necessary for cyclogenesis.
– Warm sea temperature (> 26°C) provides the necessary heat and moisture.
– High relative humidity in the lower and mid-troposphere is crucial for cloud formation and thunderstorm development.
– Atmospheric instability allows for vigorous vertical convection, which drives the storm’s development.
Tropical cyclones develop in stages: formation/initial stage, juvenile/modification stage, mature stage, and decay stage. The listed conditions are specific requirements for the *formation* stage, where a tropical disturbance begins to organize and intensify into a tropical depression or storm.
