How does a thunderstorm become a cyclone?

Answer 1

We know that when the water changes its state, heat is evolved.

So,

Before cloud formation, water takes up heat from the atmosphere to change into vapour. When water vapour changes back to liquid, in the form of rain drops, this heat is released in to the air, thus heating the surrounding air. Now this warm air tends to rise and causes a drop in pressure. More air rushes to the centre of the storm. This cycle is repeated. The chain of events results in the formation of a very very low pressure system with high speed winds revolving around it. It is these weather conditions which are called a cyclone.

Answer 2

Thunderstorms do become cyclones.

Cyclones begin as tropical storms out over the ocean, but in order to develop into cyclones, there are certain conditions that are required.

Firstly, the sea temperature must be a minimum of 26.5 degrees Celsius. Then, they can only occur in areas of very low pressure when air that is heated by the sun rises rapidly, and becomes saturated with moisture which then condenses into high thunderclouds. As the atmosphere becomes favorable for development (no wind shearing in the higher parts of the atmosphere), normal thunderstorms clump together.

It may seem that thunderstorms do not become cyclones for the simple reason that we tend to only observe the phenomenon of a thunderstorm when we are on land. Cyclones cannot develop over land, and they also take many days (sometimes weeks) to actually develop from storm into a low pressure system, and then into a cyclone.

Answer 3

A cyclone is a large scale, organized weather system that does not necessarily involve thunderstorms. Tropical cyclones develop from clusters of thunderstorms only if there is little wind shear and a sufficient supply of moisture from warm ocean water There must also be adequate Coriolis force to allow the system tor organize. In temperate climates, thunderstorms are often the result of a cyclone and its associated fronts, so in that case the cyclone is already established. Those that develop without a cyclone are too weak, too disorganized, and/or occur on too small of a scale.

Answer 4

Tropical cyclones develop from thunderstorm, but mid-latitude cyclones do not.

We start off with a cluster of showers and thunderstorms in the tropics that form a low pressure area called a tropical disturbance. When this disturbance moves over warm ocean water it strengthens, fueled by the warm, moist air. The strenthening updrafts of the thunderstorms lower the pressure, allowing the system to draw in more air. As the system pulls in air, the Coriolis effect, a consequence of Earth's spin causes the system to start rotating. The system continues to intensify and the rotation becomes more organized, allowing it to pull in air more efficiently, which causes further strenthening and an increase in wind speed. Once the rotation develops a defined center the disturbance is deemed a tropical depression, the first stage of a tropical cyclone. Through most of its development, the most intense activity in the storm has been at its center, but around the point that it reaches hurricane strength, the winds are spinning so fast that they cannot reach all the way to the center. At this point the strongest leave the center, forming a calm area called the eye. The intense activity shifts to a ring just outside called the eye wall. Sinking air clears the clouds in the eye, giving it its classic appearance.

Answer 5

Thunderstorms NEVER become hurricanes. However, many hurricanes, as they move inland, devolve into heavy thunderstorms.
