As the wind passes over the ocean’s surface, water evaporates (turns into water vapor) and rises. As it rises, the water vapor cools, and condenses back into large water droplets, forming large cumulonimbus clouds. These clouds are just the beginning.
What is the first step of a hurricane forming?
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
What happens first in a hurricane?
The first stage of a hurricane is the “tropical depression” stage. For a storm to be classified as a tropical depression, it needs to be a low-pressure system involving thunderstorms, with wind speeds up to 61 kilometers per hour (38 mph or 33 knots).
What are the steps in the development of a hurricane?
Meteorologists have divided the development of a tropical cyclone into four stages: Tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone. When the water vapor from the warm ocean condenses to form clouds, it releases its heat to the air.
What are the 3 stages of development of a hurricane?
Stages Of A Hurricane
- Tropical Disturbance. A tropical disturbance is this formation of loosely packed rain clouds forming thunderstorms. …
- Tropical Depression. A tropical disturbance requires specific criteria to take the next step to become a tropical depression. …
- Tropical Storm. …
- Hurricanes. …
What are the 5 parts of a hurricane?
A hurricane consists of five main parts: outflow, feeder bands, eyewall, eye, and the storm surge. Outflow is the high-level clouds moving outward from the hurricane. Feeder bands are the areas of heavy rain and gusty winds fed by the warm ocean.
Where do hurricanes occur?
Hurricanes originate in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, the eastern North Pacific Ocean, and, less frequently, the central North Pacific Ocean.
Where do most hurricanes start?
Hurricanes start near the Caribbean, Mexico and Central America. Typhoons start near the Philippines, China and Japan. In the South Pacific and the Indian Ocean, these storms are just called cyclones.
Which of the following stages of hurricane development provides a name for the storm?
The Tropical Depression becomes a Tropical Storm when rain and thunderstorm activity moves over the closed circulation and sustained winds reach at least 39 mph. At this stage, the system can cause damage. It is at this stage that the storm is given a name.
What stage in hurricane development is the storm given a name?
Tropical Storm (Third Stage) – Tropical Depressions develop into Tropical Storms once the maximum sustained winds have intensified to between 39 and 73 mph. The storm begins to look more like a hurricane with its circular shape. It is now given a name or title.
Why do hurricanes start in Africa?
Because of the circulation of the atmosphere over this part of Africa the wind tends to blow from east to west. The flow of the air essentially gives the showers and storms over Africa a ride, directing them westward toward the Atlantic Ocean.
