Condition necessary for the development of cyclonic storm:
There are several conditions that are necessary for the development of a cyclonic storm. These include:
1. Atmospheric instability:
- Cyclonic storms are formed due to the combination of warm and cold air masses.
- The presence of atmospheric instability, such as a significant difference in temperature and pressure between these air masses, provides the necessary conditions for the development of a cyclonic storm.
- This instability creates a favorable environment for the formation of cyclones.
2. High relative humidity:
- High levels of moisture in the atmosphere are essential for the development and intensification of a cyclonic storm.
- The presence of high relative humidity promotes the condensation of water vapor, leading to the formation of clouds and precipitation.
- This moisture supply is crucial for the sustenance and strengthening of the cyclonic system.
3. Warm sea temperature:
- Cyclonic storms derive their energy from warm ocean waters.
- The presence of a warm sea surface temperature of at least 26.5°C (79.7°F) is necessary for the development and intensification of a cyclonic storm.
- The warm sea surface temperature provides the necessary heat and moisture for the storm system to grow and strengthen.
4. All of the above:
- All the aforementioned conditions are necessary for the development of a cyclonic storm.
- Atmospheric instability, high relative humidity, and warm sea temperature act together to create a conducive environment for the formation and intensification of cyclones.
In conclusion, the development of a cyclonic storm requires atmospheric instability, high relative humidity, and warm sea temperature. These conditions provide the necessary ingredients for the formation, sustenance, and strengthening of cyclones.
