What is the trigger for most Indian Ocean cyclones?
The most influential factors are:
- a source of warm, moist air derived from tropical oceans with sea surface temperatures normally in the region of, or in excess, of 27 °C;
- winds near the ocean surface blowing from different directions converging and causing air to rise and storm clouds to form;
What is the cause of frequent cyclones in India?
According to Mahesh Palawat, Meteorologist, Skymet Weather, the credit for the cyclogenesis can be given to climate change. Indian seas have been exceptionally warmer than usual this year, making atmospheric and ocean conditions favourable for frequent formation of cyclones and their rapid intensification.
Why are there so many cyclones in the Indian Ocean?
The rising surface temperatures of the waters over the Arabian Sea is thought to be a leading factor in the increasing frequency and intensity of cyclones over it. Experts have also called for intensive monitoring of these waters for cyclones.
What are the main causes of cyclones?
Cyclones are wind storms accompanied with heavy rainfall at low-pressure areas. They are caused due to a continuous process of rising of hot air over the ocean surface. This vacant space is then occupied by the cool air around, which further heats up and rises.
How can we prevent cyclones?
Planting trees to prevent cyclone damage. This reduces the frontal gust damage by deflecting and redirecting wind. Reduce the height of taller trees – a group of trees and tall shrubs together (of equal height) can divert wind through funneling.
What are the types of cyclones?
There are two types of cyclones:
- Tropical cyclones; and.
- Extra Tropical cyclones (also called Temperate cyclones or middle latitude cyclones or Frontal cyclones or Wave Cyclones).
What are the 4 types of cyclones?

Which is the dangerous storm in the world?
It is the 50th anniversary of Cyclone Bhola, the world’s deadliest known tropical cyclone which killed up to 500 000 people in what is now Bangladesh. It prompted calls for action to prevent a repeat of such a catastrophic loss of life and ultimately laid the foundations of WMO’s Tropical Cyclone Programme.
