hurricanes

BY RYAN HENSON

how do huricanes develop in the atlantic ocean?

hurricanes develop in the atlantic ocean because of its warm water. the warmer the water is, the bigger the hurricane will be. if it reaches land or the water gets to cold it will begin to get weaker until eventually it will go away.

WHAT IS THE BERMUDA HIGH???

The Bermuda High is a high pressure area that is usually set during the spring and summer periods.This area is responsible for the prolonged heat waves in the atlantic ocean.since winds blow clockwise around high pressure areas in the northern hemisphere, a south to southwest wind transports heat and humidity into the Mid-Atlantic States. the higher the pressure is around a certain area the more chances of a hurricane happening. and if a hurricane has already formed, that high pressure will make the hurricane even stronger, especialy if the water is warm and the air is humid.

WHAT IS THE EL NINO???

el Nino is an abnormal warming of surface ocean waters in the tropical atlantic. it happens every 3-7 years. while the El Nino is mostly clear during the winter times it can be harsh and brutal during the spring and summer times.

What are El Nino's weather patterns???

  • Cooler and wetter weather to the southern United States
  • Warmer weather to western Canada and southern Alaska
  • Drier weather to the Pacific Northwest
  • Cooler weather to northern Canada
  • Wetter weather to southern California

EL nino facts and information

  • El Niño usually brings a warm winter to the northern USA from the Pacific Northwest across to the Midwest and sometimes the Northeast. this warm weather can cause lots and lots of hurricanes some big and some small. Every 3-7 years for some not well-understood reason, trade winds in eastern Asia weaken. This weakening causes warm water to pile up and through natural ocean currents this warmer water migrates towards the atlantic oceans.

what is the Coriolis effect???

The Coriolis effect is the global winds, ocean currents, and everything else that moves freely across the Earth's surface. it Offers a fairly simple explanation of why objects curve on the Earth and when they should move straight.its basically what moves the axis of earth around and around.

what are the stages of development of a hurricane???

STAGE ONE-simple thunderstorms. can be heavy or light ones depending on how strong the hurricane is determined to be.

STAGE TWO- tropical depressions.forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph.

STAGE THREE- tropical storm. very intense low-pressure wind system, forming over tropical oceans and with winds of hurricane force.

STAGE FOUR- hurricane.It can be dangerously up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph.Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. when it reaches land it begins to weaken.

WHAT IS THE EYE OF A HURRICANE???

The eye is a region of mostly calm weather at the center of strong tropical cyclones. Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach it. The Coriolis force deflects the wind slightly away from the center, causing the wind to rotate around the center of the hurricane (the eye wall), leaving the exact center calm. if you were right in the eye of the hurricane it would seem like a sunny ordinary day. (until the other side of the wall reaches you)
