According to WMO (World Meteorological Organization)- “Cyclone is a low pressure system with sustained winds of atleast 34 knots (63 km/h) and a closed circulation pattern.”
Favourable conditions for the formation of Tropical Cyclones-
- High Humidity i.e around 60-80%.
- Vertical Wind Shear should be low (< 10 m/s).
- Warm Ocean waters with temperature ≥ 26.5 °C .
- Low pressure area.
- Convergence of winds with the upper level of divergence.
- Presence of Coriolis Force.
Differences between Tropical and Temperate Cyclones –
- Origin – Tropical cyclones form only on seas with temperature more than 26.5 °C in between 10° to 30° N and S of the equator ex-Hurricanes whereas Temperate cyclones can be formed both on land as well as seas in between 35° to 65° N and S of equator ex- European Windstorms .
- Shape – Tropical cyclones are elliptical in shape where as Temperate cyclones are in shape of of inverted V .
- Lifespan – Tropical cyclones doesn’t last for more than 1 week whereas Temperate cyclones may last for 2 to 3 weeks .
- Movement – Tropical cyclones move westward then poleward whereas Temperate cyclones move eastward then northeastward.
- Intensity – Tropical cyclones are more intense(Category 1 to 5) as compared to the Temperate cyclones.
Understanding these favourable conditions and differences will help us to predict,prepare and track the movements of cyclones by using effective mitigation strategies like – early warning system,storm shelters, evacuation drills,remote sensing etc .

Cyclones and anticyclones are both large-scale air masses, but they exhibit opposite characteristics.
Similarities:
1. Atmospheric Phenomena: Both are significant weather systems that influence weather patterns.
2. Pressure Systems: Cyclones and anticyclones are associated with air pressure systems, with cyclones linked to low pressure and anticyclones to high pressure.
3. Rotation: Both systems rotate due to the Coriolis effect caused by Earth’s rotation, but in opposite directions.
Differences:
1. Pressure: Cyclones are low-pressure systems where air converges and rises, leading to cloud formation and precipitation. Anticyclones are high-pressure systems where air descends, resulting in clear, dry conditions.
2. Rotation Direction: In the Northern Hemisphere, cyclones rotate counterclockwise, while anticyclones rotate clockwise. In the Southern Hemisphere, cyclones rotate clockwise and anticyclones counterclockwise.
3. Weather Impact: Cyclones often bring storms, strong winds, and heavy rain, potentially causing severe weather events like hurricanes or typhoons. Anticyclones generally bring calm, stable weather with clear skies and little precipitation.
In summary, while both cyclones and anticyclones are crucial to understanding weather patterns, they represent contrasting pressure systems and weather conditions, with cyclones bringing turbulent weather and anticyclones bringing stable conditions.
