A hurricane also releases energy through the formation of clouds and rain (it takes energy to evaporate all that water). If we crunch the numbers for an average hurricane (1.5 cm/day of rain, circle radius of 665 km), we get a gigantic amount of energy: 6.0 x 10^14 Watts or 5.2 x 10^19 Joules/day!
This of course begs the question “How do Hurricanes keep their energy?”

One of the next things we wondered was how do hurricanes gather heat and energy?
The most common answer is, hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an “eye” in the Northern Hemisphere and clockwise direction in the Southern Hemisphere.
Hurricanes are large weather engines, and any engine needs energy to run. The secret energy source of a hurricane is the large latent heat of water. Air over the tropical oceans is drier than you might think.
The energy required to make this change comes from the sun, and this energy is lying in wait — latent — ready to be released when the vapor is condensed into liquid again. This happens in rising air in a cloud or thunderstorm. However, this process alone is not enough to power a hurricane.
Another frequently asked inquiry is “Do hurricanes gain energy as they near land?”.
This is what my research found. once a hurricane reaches cooler water or land, the energy source is gone and the hurricane will slowly diminish and release less energy. Powerful hurricanes hold an enormous potential as renewable energy sources, and one aspect of these storms is the renewable wind energy that can be harnessed.
Do Hurricanes get their heat and energy Fron seawater?
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. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well.
How do Hurricanes work?
How Hurricanes Work (Infographic) A hurricane is a giant heat engine, converting the energy of warm ocean air into powerful winds and waves. A distinctive feature is that their center is warmer than the surrounding air in what’s called a warm core storm system. A hurricane requires warm ocean water (the “fuel” of a hurricane).
One answer is a hurricane adds fuel to its own fire by drawing surface air toward its low-pressure center. The tight pressure gradient nearer the center means that the winds grow stronger as the air approaches the eye. The faster the wind blows, the more evaporation takes place (this is why you blow-dry wet hair or hands instead of merely warming them).
Another popular inquiry is “How is a hurricane formed?”.
These storms have different names around the world but all of them form the same way, in the warm ocean waters near the Earth’s equator. A hurricane is a giant heat engine, converting the energy of warm ocean air into powerful winds and waves.
What happens when a hurricane strikes the ocean?
Powerful thunderstorms (rain bands) spiral outward from the eye. The high winds of a hurricane sweep across the ocean water producing a dangerous storm surge, a wall of water that can cause massive flooding even miles inland.
How do hurricanes transfer heat?
Heat is transferred from the ocean to the atmosphere when water at the ocean’s surface evaporates to become water vapor. In the lower troposphere, air parcels carry heat energy obtained from the ocean. These air parcels spiral inward towards the center of the developing hurricane.
As you work through the activities, keep in mind that we’re not just interested in heat transfer, but how heat transfer affects hurricane formation and intensification. The take-home message is that warmer ocean water evaporates more easily and that means that more heat energy makes its way into the atmosphere.
Why do Hurricanes only form over warm water?
Hurricanes only form over really warm ocean water of 80°F or warmer. The atmosphere (the air) must cool off very quickly the higher you go. The wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface.
How many miles per hour does a hurricane move?
Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power.
