How many hurricanes are there each year?

How many hurricanes are there each year?
about 85 named storms worldwide, of which roughly 45 reach hurricane strength
An average season produces roughly three storms a fortnight somewhere on Earth, but the Atlantic — which dominates English-language coverage — accounts for only about one storm in six.

Across all ocean basins there are around 85 named tropical storms a year and roughly 45 of them reach hurricane or typhoon strength — sustained winds of 74 mph or more. The Atlantic contributes about 14 named storms and 7 hurricanes in an average season; the western Pacific, which is the busiest basin on Earth, produces about 26 named storms. The global total is remarkably stable year to year even when individual basins swing wildly, because El Niño suppresses the Atlantic while enhancing the Pacific.

How the figure is arrived at

Storms are named by regional warning centres when sustained winds reach 39 mph, so the count is a definitional one applied consistently. Satellite coverage since the 1970s means nothing is missed now; earlier records under-count storms that stayed at sea, which is why long-term trend claims need care.
