Hurricane Catarina was an extraordinarily rare hurricane-strength tropical cyclone, forming in the southern Atlantic Ocean in March 2004. [13] Just after becoming a hurricane, it hit the southern coast of Brazil in the state of Santa Catarina on the evening of 28 March, with winds up to 140 kilometres per hour (87 mph) making it a Category 1 ...
Magnetic anomalies off west coast of North America. Dashed lines are spreading centers on mid-ocean ridges. The Vine–Matthews-Morley hypothesis correlates the symmetric magnetic patterns seen on the seafloor with geomagnetic field reversals. At mid-ocean ridges, new crust is created by the injection, extrusion, and solidification of magma.
Hurricanes help to maintain the global heat balance by moving warm, moist tropical air to the mid-latitudes and polar regions [5] and also by influencing ocean heat transport. [6] Were it not for the movement of heat poleward (through other means as well as hurricanes), the tropical regions would be unbearably hot.
Hurricanes need two main ingredients — warm ocean water and moist, humid air. When warm seawater evaporates, its heat energy is transferred to the atmosphere. This fuels the storm's winds to ...
Surface-level sea temperatures have to be at least 80 degrees for a hurricane to form, Anderson said. The ocean waters along the West Coast are typically a chilly 50 to 65 degrees.
The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall , but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces.

Climate change is intensifying storms because higher ocean temperatures act as fuel and a warmer atmosphere allows for heavier rain over land. For every 1 degree Fahrenheit of warming, the ...
The destruction from early 21st century Atlantic Ocean hurricanes, such as Hurricanes Katrina, Wilma, and Sandy, caused a substantial upsurge in interest in the subject of climate change and hurricanes by news media and the wider public, and concerns that global climatic change may have played a significant role in those events. In 2005 and ...
