In 2017 alone there was 17 named hurricanes. In those 17 some are Major hurricanes of category 3 or higher.

Warm Seas powers the Hurricanes and as we can see that globally the average sea temperature have risen by 1 degree C.

Lack of upper-level wind flow or lower pockets of moisture, a wetter monsoon was some of the factors leading to these frequent extreme weather phenomenons.

Rising temperatures leads to warmer air holding more moisture, this further leads to more intense rain during a hurricane. It then becomes a factor in flood like situation.

 What can Stop forming of Hurricanes

Strong winds prevents the formation of Hurricanes.

Seas are getting warmer but then some factors associated with it can stop formation of Hurricanes.

Strong Winds can stop the storm growing into a hurricane.  El nino years are quiet years for hurricanes because of this reason only. Because during an El Nino year, Pacific Ocean near the Equator gets warmer than usual.

This warming then affects Wind pattern globally which leads to stronger winds in the Atlantic. It further  affects the storm growing into Hurricanes.

Opposite is true for La Nina years when the Pacific ocean is cooler.

Thus helping in the formation of Hurricanes. So you can see many hurricanes in La Nina year, like what we saw in 2017.

Typhoon Vs Hurricanes Vs Cyclone.

These all are same weather phenomenon, but named depending on where they occur.

In Southeastern Indian Ocean & southwestern Pacific, its termed as Severe Tropical Cyclones.

These Powerful and severe cyclones are called as Typhoons in the northwestern Pacific.

In the Northern Pacific and Atlantic, the Storms are called Hurricanes. Named after the Carribean God of Evil, Hurrican.

 All has winds stronger than 118km perhour.
