Why do atlantic hurricanes move north




















Winds passing to and from the North and South Poles and the equator are subject to this effect. Imagine if a person were to stand at the North Pole and throw a ball far enough to reach the equator — say, to a person standing in Quito, Ecuador — the ball would not actually reach that person because it would not travel in a straight line. Since the equatorial region is moving faster than the North Pole, the ball would end up to the west of its target — somewhere in the Pacific Ocean, probably.

The same thing would happen in the Northern Hemisphere if someone were to throw a ball from south to north, only the ball would end up east of its intended target. This is what happens to the winds that travel to and from the poles. In the Northern Hemisphere, winds moving north are diverted eastward, and winds moving south are diverted westward. In the Southern Hemisphere, winds traveling toward the equator will move eastward, and winds traveling toward the South Pole will curve west.

When these winds collide, they will swirl clockwise in the south, and counterclockwise in the north. A variety of factors influence how hurricanes form. Movement of Hurricanes steered by the global winds The global wind pattern is also known as the "general circulation" and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From degrees latitude.

Prevailing Westerlies: From degrees latitude aka Westerlies. Tropical Easterlies: From degrees latitude aka Trade Winds. The easterly trade winds of both hemispheres converge at an area near the equator called the "Intertropical Convergence Zone ITCZ ", producing a narrow band of clouds and thunderstorms that encircle portions of the globe.

East Coast," the U. National Hurricane Center in Miami said in a bulletin Tuesday. Monday afternoon, Earl was located about 1, miles km southeast of Cape Hatteras, North Carolina, moving west-northwest at 14 mph 22 kph.

Once storms move north of Cape Hatteras, they tend to drastically accelerate due to the area's weather systems.

A storm with a forward speed of 10 to 15 mph can accelerate to 20, 30, or even 50 mph in extreme cases. Such extremes are rare, but a hurricane in raced from Cape Hatteras to Long Island in a matter of hours, at an average speed of 50 mph.

In the morning of Sept. Though the storm weakened, its forward speed was so great that it arrived in the Northeast before losing all its punch, creating foot storm surges that swamped Providence, RI. It was in Canada by nightfall, having killed people along the way. Live Science.
