The Development of a Tropical Cyclone
The development of a tropical cyclone is divided into four stages by the Meteorologists department, such as-
- Tropical disturbance, where the heated ocean’s water vaporizes and releases its heat to the atmosphere when it condenses to form clouds. Warm air rises and draws into the column of cloud. Condensation and evaporation keep going on and increase the height and size of the columns of the cloud. As a pattern emerges, the wind circles around the centre. A tropical disturbance is a collection of thunderstorm clouds that form by encountering more clouds.
- In tropical depression, where the air towards the top of the cloud column is cooling and getting unstable as the thunderstorm rises higher and higher. The heat energy from the cooling water vapour is released when the air at the top of the clouds warms up by raising the air pressure and driving winds to travel away from the high-pressure area. As a result the pressures at the surface decrease. More thunderstorms are developed when the surface air rises and travels into the area of lower pressure. The storm cloud column’s winds are whipping around in a circle as they become quicker and faster. Whenever a storm’s winds are between 26 and 37 mph, it is referred to as a tropical depression.
- A tropical cyclone, A tropical depression develops into a tropical cyclone, when wind speeds reach 39 mph. The storm is also given a name at this time. The storm’s eye, or calm core, is swiftly surrounded by swirling winds. In the northern hemisphere, the wind blows anticlockwise (from west to east), while in the southern hemisphere, the wind blows clockwise (from east to west). This situation is called The Coriolis effect.
- Hurricane, When the speeds of the wind reach 75 mph, the storm is officially called a hurricane. the storm spans an area of about 125 miles and at least 50,000 feet high. The eye’s width ranges from 5 to 30 miles. The trade winds blow from the east towards the west. It pushed The hurricane toward the west. A massive accumulation of ocean water is also surrounded by the hurricane’s eye due to the low air pressure and the winds. When the water reaches land, it can result in enormous storm surges.
What is Hurricane?
Among tropical cyclones, a hurricane is one of them. A tropical cyclone is a weather system that rotates rapidly. It is characterized by a low-pressure centre and a closed atmospheric circulation at low elevations. It also has an arrangement of thunderstorms which is a spiral that produces heavy rain. A hurricane occurs in the northeast of the Pacific Ocean, the Atlantic Ocean, the northwest of the Pacific Ocean, or in the Indian Ocean. The biggest and most destructive storms on Earth are hurricanes.
