OF CYCLONES BY YEAR
In the Atlantic ocean, is observed each
year on average ten tropical cyclones. Only
half of them reach the coasts of the USA every
3 years approximately. From 1900 to 1978 : 129
hurricanes have hit the USA, including 50 in
Since 1930 the hurricanes have increased
in the North Atlantic. From 1886 to 2005 on
average each year there were 9 hurricanes. And
then from 1945 to 2005 there were approximately
11 hurricanes per year and between 1990 and
2010 the average is passed to 14 hurricanes
80-85 cyclones can form each year on our
planet, including 45 with winds greater than
72,7 mph (117 km/h). 68% are listed in the hemisphere
North and 32% only in the southern hemisphere.
On average between 1990 and 2010, 58% of cyclones
and tropical storms formed in the Pacific including
32% to the West, 17% to the East and 9% to the
South Pacific and then 14% of hurricanes and
tropical storms formed in the North Atlantic
and 28% of cyclones and tropical storms formed
in the Indian Ocean including 5% in the South
and 23% Northern Indian Ocean.
In relation to the total number of tropical
storms and hurricanes of category 1 to 5, in
the Pacific ocean there is a higher percentage
of violent cyclones in the Atlantic Ocean as
we watch the two graphs below.
Comparison between the evolution of the number
of cyclones in the Eastern Pacific and
North Atlantic according to the evolution of E.N.S.O
(El Nino or La Nina or La Nada).
This graph was created and is updated based the data
So every year it is possible to predict
areas where there is the greatest risk of having tropical
storms and cyclones.
