The statistical peak of the hurricane season is today. Why was the Atlantic Ocean very calm?

Often you see the summer and autumn months The Atlantic Hurricane Season From June 1 and continued until November 30. Historically, on average, the number of hurricanes and tropical storms on September 10.

But this year was quieter than expected when it came to tropical systems in the Atlantic Ocean, which makes some wonder: Where are all hurricanes?

Looking at the Atlantic Ocean basin, most of the tropical waves that eventually enhance the tropical systems start from the coast of Africa and move through the warm ocean water. But this year, Desert Continue moving over the open water, preventing the development of thunderstorms needed to form a tropical hurricane.

Dust from Africa usually move across the Atlantic Ocean every year, usually stipulating peak from late June to mid -August. However, the high pressure in its place over the central North Atlantic Ocean allows fewer storms to develop in North Africa, creating the ideal conditions for dry dust to move.

The planet is Also in a cycle known as “ENSO Neutral”, which means that there is neither El Nino nor La Nina. During the Nino, the winds close to the equator are weakened, allowing the warm water to be pushed east. No Nina has an opposite effect from El Nino. During the events of La Nina, the wind around the equator is stronger than usual, bringing the most cold water in the east.

When La Nina is present, the East Pacific Hurricanes occur in the east and more Atlantic hurricanes, and vice versa for El Nino periods. Since there is currently not, we do not have a typical hurricane season.

According to the World Meteorological Organization, we It is expected to move to La Nina in the next fall and winter months, and the current lack of hurricane activity indicates the beginning of the transition period.

The hurricane season away from completion

The National Administration of Oceanic and Air Force, or NOAA updated its expectations for the season in August of its original analysis in May, which expected a little less than the enemies called. But he confirms that the Atlantic Ocean will witness a season over the average.

The hurricane season is still out of completion. As of September 10, 60 % of them remain.

NOAA predicts that ATLANTIC will witness between 13 and 18 years named as the storm this season, as it reinforces up to nine hurricanes up to five storms in Category 5, which is the strongest.

To date, six tropical systems have evolved in the Atlantic Ocean – Andrea, Barry, Chantal, Dexter, Irene, Fernand. Irene was the only one he reached Hurricane power. In the United States, only one system achieved this season – remnants of CHANTAL.

By this time last year, the same number of storms we saw this year formed – six – formed. But three of them arrived on land in the United States: Beare, Deby And Fansin.

After statistical peak on September 10, other major hurricanes developed: Helen and MiltonLater this season. Milton achieved a decline in the United States and destroyed parts of the southeast.

In total last year, 19 tropical systems were formed in the Atlantic Ocean.
