At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin. Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards.

How do convection currents affect hurricanes?
This instability increases the likelihood of convection, which leads to strong updrafts (red arrows) that lift the air and moisture upwards, creating an environment favorable for the development of large cumulonimbus clouds. A tropical disturbance is born, the first stage of a developing hurricane.
What makes a hurricane stronger?
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. ... And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes.
How a hurricane is formed?
Hurricanes form when warm moist air over water begins to rise. The rising air is replaced by cooler air. This process continues to grow large clouds and thunderstorms. These thunderstorms continue to grow and begin to rotate thanks to earth's Coriolis Effect.
How does convection cause hurricanes to form?
Hurricanes: Science and Society: Convection. Convection is the transfer of heat by movement of a fluid such as air. Convection happens in the atmosphere when air near the Earth's surface is heated. This heating causes the air to expand, become less dense than the surrounding air, and rise.
How does convection play a role in ocean currents?
Convection currents play a role in the circulation of fluids. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. ... Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.
What weakens a hurricane?
As less moisture is evaporated into the atmosphere to supply cloud formation, the storm weakens. Sometimes, even in the tropical oceans, colder water churned up from beneath the sea surface by the hurricane can cause the hurricane to weaken (see Interaction between a Hurricane and the Ocean).
Is a Cat 6 hurricane possible?
There is no such thing as a Category 6 storm, in part because once winds reach Category 5 status, it doesn't matter what you call it, it's really, really, bad. The scale starts with a Category 1, which ranges from 74 to 95 mph (119 to 153 km/h). A Category 5 storm has winds of 156 mph (251 km/h) or stronger.
How do ocean currents influence the strength of a hurricane when it makes landfall?
At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin. ... Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.
What are hurricanes effects?
Hurricanes are one of nature's most powerful storms. They produce strong winds, storm surge flooding, and heavy rainfall that can lead to inland flooding, tornadoes, and rip currents.
Why do hurricanes spin?
As mentioned in a previous Breakdown, air always likes to travel from high to low pressure, so it will move toward the storm. As the air moves to the storm, in the northern hemisphere, it will get turned to the right. This then creates a spinning motion that is counter clockwise.
How are hurricanes named?
NOAA's National Hurricane Center does not control the naming of tropical storms. Instead, there is a strict procedure established by the World Meteorological Organization. For Atlantic hurricanes, there is a list of male and female names which are used on a six-year rotation.
Why can hurricanes not form at the equator?
Note on the map that tropical cyclones don't form near the equator (the Coriolis force is too weak to initiate rotation) and they don't form far away from the equator (water temperatures are too cold). Therefore, tropical cyclones typically form within a band of latitudes.
How is heat transfer involved in hurricanes?
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.
What does the Coriolis effect have to do with hurricanes?
The Coriolis Effect influences wind patterns, which in turn dictate how ocean currents move. ... For instance, due to the Coriolis Effect, hurricanes in the Northern Hemisphere spin in a counterclockwise direction, while hurricanes in the Southern Hemisphere (known as cyclones) spin in a clockwise direction.
How do currents affect the ocean?
By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places.
What effect do currents have on objects in the ocean?
Surface currents play a large role in determining climate. These currents bring warm water from the equator to cooler parts of the ocean; they transfer heat energy.
How ocean currents affect regional climates?
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe.
