Imagine a pot of water boiling on your stove. The heat from the stove warms up the water, and eventually, it starts to evaporate, turning from a liquid to a gas. This is similar to the start of a hurricane. The sun's heat warms up the ocean surface, causing the water to evaporate. As this warm, moist air rises, it creates an area of low pressure beneath it. Air from the surrounding higher pressure areas rushes in to fill this low pressure space, and as it does, it too gets warmed and rises. This continuous cycle causes the wind speed to increase, forming a cyclone of air and clouds. This is what we call a hurricane.
Picture this process like a bathtub filling with water. The tap, pouring warm water (like the sun warming the ocean), is the source. The drain, where the water leaves (like the warm air rising), creates a low-pressure area. The more water you add, the more the drain works to eliminate it, and the faster the water circulates in the tub. This is how a hurricane's wind speed intensifies.

Building on the basics, the formation of hurricanes is driven by a combination of various atmospheric conditions. These storms are born over tropical or subtropical waters, where the ocean temperature is at least 26.5 degrees Celsius. The warm, moist air acts as the hurricane's fuel, and the heat energy from the water's evaporation increases the air's humidity and temperature, causing it to rise.
As the warm air ascends, it cools down and condenses to form clouds and rain, releasing latent heat in the process. This heat warms the surrounding air, causing it to rise and creating a self-sustaining cycle of air movement. The Earth's rotation then imparts a spinning motion to the storm, leading to the formation of the hurricane's characteristic swirl.
If you've ever played with Lego bricks, you'll know that building something requires arranging and interlocking different pieces in a specific order. Similarly, a hurricane is formed by the interlocking of different 'pieces' or conditions.
Think of the warm ocean water as the base Lego plate upon which you'll build your structure. The rising warm air can be imagined as the first layer of Lego bricks that you place on the base plate. As more air rushes in to replace the rising warm air (more Lego bricks), you're gradually building up your structure, or in this case, the storm.
The spinning motion of the hurricane can be compared to a rotating Lego structure on a turntable base. Now, if you remove the base plate (the warm water), or stop adding Lego bricks (the warm, moist air), your structure will stop growing. Similarly, if a hurricane moves over land or colder water, it loses its 'fuel' and weakens. The Lego analogy provides a simplified, but insightful understanding of the complex process of hurricane formation.

From a meteorological standpoint, hurricanes, also known as tropical cyclones, are complex weather systems that rely on an interplay of the ocean and atmosphere. The fundamental driver is the heat energy from the warm ocean surface, which is transferred to the atmosphere through evaporation and condensation processes.
As the saturated air rises, it creates an upward convective current, leading to an area of low pressure at the ocean surface. This triggers the inflow of surrounding air, which gets heated and rises, strengthening the cyclone. The release of latent heat through condensation further fuels the cyclone's intensification.
The Coriolis effect, caused by the Earth's rotation, induces a rotational motion to the cyclone, giving it its distinctive spiral shape. For a storm to be classified as a hurricane, its wind speed must reach at least 74 miles per hour. The hurricane will continue to grow as long as it remains over warm waters and encounters minimal wind shear.
