Every recorded hurricane, cyclone, and typhoon since 1850
Based on the NOAA’s historical tropical storm tracks data, which includes storms dating as far back as 1850, the map above shows a top-down view of every hurricane, cyclone, and typhoon in recorded history.
Hurricane, cyclone, and typhoon are all terms for the same phenomenon (technically tropical cyclone) in different parts of the world. They all refer to a tropical storm with sustained wind speeds of at least 74 mph.
View from the southern hemisphere
The other day I wrote a post on fracking and induced earthquakes, an area of earthquake science that has gone misunderstood / misreported. Having formerly worked as a catastrophe modeler, it occurred to me there is also a recent trend in hurricanes that has largely been overlooked.
The U.S. is currently going through an extended period of hurricane inactivity, with no major hurricanes having made landfall in the last 11 years. As a result, hurricanes have not received the media attention they deserve.
Though 2015 was a quiet year in the North Atlantic, from a worldwide perspective, last year’s tropical storm season was the most intense in recorded history.
The U.S. is currently experiencing its longest hurricane drought in recorded history
In the U.S., no major hurricane has made landfall since hurricanes Katrina, Rita, Wilma, and Dennis struck back in 2005. A hurricane is considered “major” when it reaches category 3 status, with sustained winds of at least 111 mph.
That puts the U.S. in a hurricane drought of 11 years and counting, the longest in recorded history. The previous record of 8 years dates back to the 19th century, between 1861 and 1869.
For comparison, on average, about 2 major hurricanes make landfall in the United States every 3 years.
Meanwhile, the northern hemisphere just had its most intense tropical storm season ever
It’s surprising, but true. While the U.S. has been experiencing a hurricane drought, at least in terms of hurricanes making landfall, the northern hemisphere just had the most active tropical storm season in recorded history.
Here are just a few of the records set by last year’s tropical storms.
Tropical storm records set in 2015:
- Most major storms: Last year, the world saw 30 major storms (category 3 or higher), far above the previous record of 23, set in 2004.
- Most powerful storm: Hurricane Patricia, which formed off the coast of Mexico last October, had sustained wind speeds that peaked at 215 mph, faster than any tropical storm ever recorded.
- 2 major storms in the Arabian Sea: The Arabian Sea, where tropical storms are uncommon due to its dry and windy climate, had 2 major cyclones last year. Before last year, only 6 major cyclones had ever been recorded in the Arabian Sea.
- Easternmost hurricane: In September of last year, Hurricane Fred struck Cabo Verde, traveling further east in the Atlantic than any previous hurricane.
- Latest hurricane: Though technically part of the 2016 season, hurricane Alex became only the second ever documented January hurricane. Alex attained hurricane status on 1/14/2016, 10 days later than the previous January hurricane, which became a hurricane on 1/4/1938.

What’s behind the record-breaking intensity of last year’s tropical storms?
It’s too soon to draw any conclusions. However, several pieces of recent research suggest the Earth’s warming climate may play a role.
