hurricanes are born over which continent?
318342
Scientists have long known that hurricanes that lash the Atlantic coasts of North and Central America are born in storm systems off the west coast of northern Africa. In an ironic twist, these wettest of storms are driven by weather over one of Earth's driest of places, the Sahara (the name means desert in Arabic).

Until relatively recently, it was almost unanimously agreed upon that tropical cyclones couldn't form in the South Atlantic. The region is characterized by strong wind shear, which can easily tear apart fledgling systems. Water temperatures would usually be too cool to grow or sustain them.

A continental tropical air mass forms in the interior of subtropical continents at about 15o to 35o north and south latitude. They are hot and dry air masses due to the temperature and moisture characteristics at their source region.

Although the World Meteorological Organization now names hurricanes after men and women, storm names weren't always so equally divided by gender. From roughly 1953 to 1979, U.S. hurricanes and tropical storms were actually only named after women.

All tropical storms In the North Atlantic Ocean and Northeast Pacific, they are called hurricanes. But if the same type of disturbance takes place in the Northwest Pacific Ocean, it is known as a typhoon. And in the South Pacific and Indian Ocean, cyclone is the correct term.

Each year, an average of 10 tropical storms develop over the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. In Maine, hurricanes don't happen often but they can be devastating when they do. Previous storms that had impact on Maine are: Carol and Edna in 1954, Donna in 1960, Gloria in 1985, and Bob in 1991.

Because tropical cyclones need warm water to survive, the chances of tropical cyclone formation happening over dry land are slim. Only 2 percent of all Atlantic tropical cyclones have formed over land (1851-2015), according to Michael Lowry, hurricane specialist with The Weather Channel.

At least 15 are killed in Central America because of flooding rains. Right on cue, a tropical cyclone is forming in the Gulf of Mexico as the 2020 Atlantic hurricane season officially begins. ... Forecasts call for it to intensify into a tropical storm on Tuesday.

But it also has to do with physics. In fact, tropical cyclones — the general name for the storms called typhoons, hurricanes or cyclones in different parts of the world — always spin counterclockwise in the Northern Hemisphere, and spin in the opposite direction in the Southern Hemisphere.

Cyclones can't ever cross the equator. ... The direction the winds flow around a cyclone (and in fact any weather system) is determined by the Coriolis effect. The Coriolis effect is created by the earth's rotation. The result is wind in the southern hemisphere is deflected to the left.

Both include very strong and rotating winds that can cause significant damage. Hurricanes are formed over warm water in tropical oceans while tornadoes are formed over land. Hurricanes develop when they are far away from a jet stream and tornadoes are formed within storms very close to those jet streams.

That's because hurricanes, cyclones, and typhoons are all the same weather phenomenon. Scientists just call these storms different things depending on where they occur. In the Atlantic and northern Pacific, the storms are called "hurricanes," after the Caribbean god of evil, named Hurrican.

Tropical cyclones are like engines that require warm, moist air as fuel. So the first ingredient needed for a tropical cyclone is warm ocean water. That is why tropical cyclones form only in tropical regions where the ocean is at least 80 degrees F for at least the top 50 meters (about 165 feet) below the surface.

No known hurricane has ever crossed the equator. Hurricanes require the Coriolis force to develop and generally form at least 5° away from the equator since the Coriolis force is zero there.

Hurricanes typically form over warm water, so they are most prevalent in the places, and at the times of year, where the oceans reach their highest surface temperatures. ... Normal tropical hurricanes, though, usually go away in winter. The ocean surface gets too cold for them, even with the colder atmosphere above.

There has been little change, however, in the frequency of hurricanes globally. Roughly 90 hurricanes occur each year around the world, with by far the greatest number occurring in the largest ocean basin on Earth–the Pacific.
