formation of a hurricane
The hurricanes in the Atlantic ocean are formed by the warm, moist air along the equator and the warm and cool water which will cause the wind to gradually speed up.
Bermuda High
Bermuda high is a semipermanent area of high pressure located over Bermuda in summer and fall that steers many storm systems westward across the Atlantic.
- The wind spins around this high area in a clockwise fashion.Storms caught up in these winds are steered to different areas causing a bigger hurricane.
El NiƱo
El Nino is a irregularly occurring and a mixture of climatic changes affecting the Pacific region along the equator. Very few years they are characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
- The warming of ocean water up to 7 degrees causes much larger amounts of water to evaporate into the tropical atmosphere making it rain.
Water Tempature
when you find the water temperature you will determine if its near the equator if so then it's warmer than the north near the artic wear its a lot cooler.
- the warm water the more vapor in the air which gives energy to the wind funnel that is moving and rotating the hurricane. If the water is warm enough it will produce a strong wind which will gather moisture and begin to rotate stronger than before.
