Climate change has an immediate consequence in the form of global warming which is associated with harsh impact on both nature and living organisms.
Damage caused by cyclone is exponentially linked to the wind speed, as a result, more intense storms leads to a massive consequences on coastal and associated lives and economies. Cyclones are categorized into various segments based on their 'maximum sustained wind strength' and the intensity of potential damage. Rapid rise in the surface ocean temperature due to anthropogenic climate change is one of the major reasons of cyclone in terms of intensity and frequency.
"It is characterized by rain/storm clouds that start rotating and generate intense rains and winds, and a storm surge created by the wind," he added.
"These immensely powerful natural phenomena have different labels according to the region they hit, but cyclones, hurricanes and typhoons are all violent tropical storms that can generate 10 times as much energy as the Hiroshima atomic bomb," a global weather report mentioned.
These massive weather phenomena spanning couple of hundred kilometers, are made more destructive by their long-distance traveling ability. Different Meteorological departments observing these cyclones apply various methods to categorize them, mostly based on the oceanic basin.
When ambience is hotter, it holds more water, leading to more rainfall. That's reason behind association of excessive rainfall with cyclones in coastal areas. These torrential downpours often lead to devastating floods and mudslides, killing hundreds of people.
Natural weather variations, like El Niño or La Niña, also impact substantially on development of cyclones especially hurricanes. Scientists are eager to know about the influence of these natural variations in the future cyclone activities.
Here's a video explaining how climate change is impacting cyclone.
"The most violent cyclones — categories three to five on the Saffir-Simpson scale — that cause the most destruction have become more frequent," the WWA said.
"Tropical cyclones are the most extreme rainfall events on the planet," the WWA said.
"A rise in air temperature of three degrees Celsius (5.4 degrees Fahrenheit) can potentially produce a 20% increase in the quantity of rain generated by a cyclonic event," said Cloppet.
The WWA mentioned: "As ocean waters warm, it is reasonable to speculate that [tropical] storms will shift further away from the Equator."
"A northward shift in cyclones in the western North Pacific, striking East and Southeast Asia, [is] a direct consequence of climate change," it said.
The storm waves are much higher nowadays than in last few decades due to the sea level rise by climate change.
Unfortunately, there is still no proper theory demonstrating the number of storms or cyclones in the present climate, so it becomes tough to predict if cyclone will change it's behaviour in the future or not.
"Climate change therefore creates the conditions in which more powerful storms can form, intensify rapidly and persist to reach land, while carrying more water," the WWA mentioned. This may lead to cyclones in new locations that have not faced cyclone before.
