Tropical cyclone

Tropical cyclones are the greatest threat to life and property, even in the early stages of development. They carry a variety of hazards that can individually significantly affect life and property, such as storms, floods, high winds, tornadoes, and lightning. When these hazards mix, they move and greatly increase the potential for loss of life and property.

For this reason, we are going to dedicate this article to tell you everything you need to know about tropical cyclones, how they arise and what their consequences are.

Over the past 50 years, tropical cyclones have caused 1,942 disasters, killed 779,324 people and caused an estimated economic loss of $1.407.6 billion, equivalent to an average of 43 deaths and $78 million in damages per day.

A tropical cyclone is a rapidly rotating storm that originates in tropical oceans and attracts the energy necessary to develop. It has a low-pressure center where clouds roll in toward the wall around the "eye," the central part of the system where there are no clouds and the weather is generally calm. Its diameter is usually about 200 to 500 km, but it can also reach 1,000 km.

Tropical cyclones produce very violent winds, heavy rainfall, huge waves and in some cases very damaging storm surges and coastal flooding. Winds flow counterclockwise within the hemisphere and dextrorotary within the hemisphere. Tropical cyclones that reach a particular intensity square measure named for public safety.

This meteorological phenomenon has different names depending on where it occurs.

In the Caribbean Sea, the Gulf of Mexico, the North Atlantic, and the eastern and central North Pacific, these weather phenomena are known as "hurricanes".

In the western North Pacific, its miles known as a "typhoon".

In the Bay of Bengal and therefore the sea, it's known as a 'cyclone'.

In the southwest Pacific and southeast Indian Ocean, they are called "intense tropical cyclones".

It is referred to as a "tropical cyclone" within the southwest ocean.

Tropical cyclone and its types

Cyclones are often associated with very heavy rainfall, which can cause widespread flooding. They are associated with damaging or damaging winds, with surface wind speeds that can exceed 300 km/h in strong systems. The combination of wind-driven waves and low pressure of a tropical cyclone creates a coastal storm surge: a flood of water that rushes toward the coast at high speed and with great force, moving structures in its path and causing damage. Coast and environment.

Based on maximum sustained wind speed, tropical cyclones are designated as follows:

Tropical discouragement, with most extreme supported breezes under 63 km/h;

Tropical storms, when the maximum sustained wind speed is greater than 63 km/h, are called such storms;

A hurricane, typhoon, severe tropical cyclone or severe cyclone (depending on the basin) when the maximum sustained winds exceed 116 km/h.

Hurricane intensity ranges from class one to class five on the Saffir-Simpson cyclone Scale employed in the Caribbean, Gulf of Mexico, North Atlantic, and Japanese and Central North Pacific:

Category 1 hurricanes are those with the most sustained winds Between 119 and 153 km/h.

Category 2 hurricanes are those with the most sustained winds Between 154 and 177 km/h.

Category 3 hurricanes are those with the most sustained winds Between 178 and 209 km/h.

Category 4 hurricanes are those with the most sustained winds Between 210 and 249 km/h.

Category 5 hurricanes are those with the most sustained winds Over 249 km/h.


The impact of tropical cyclones and the damage caused by them depends not only on the wind speed, but also on the speed of travel, the duration of strong winds, the amount and variation of rainfall during and after landfall. The direction of migration and the contingency of power, its composition (such as size and strength), and human response to disturbances caused by these systems.


Tropical Cyclone Forecasting

Meteorologists around the world use modern technology such as satellites, weather radar and computers to predict the development paths of tropical cyclones. Tropical cyclones are now and again unpredictable due to the fact they all at once weaken or alternate course. However, meteorologists use sophisticated technology and develop modern techniques, such as numerical weather prediction models, to predict a tropical cyclone's trajectory, including changes in its trajectory and intensity, when and where it makes landfall, and how quickly it makes landfall. The National Meteorological Service of the affected country is then responsible for issuing official warnings.

About 80 tropical cyclones form each year. WMO Tropical Cyclone Program This hazard and severe weather information center provides information WMO issues tropical cyclone warnings in real time.

The WMO Framework allows for comprehensive and timely dissemination of information on tropical cyclones. Thanks to international cooperation and coordination, an increasing number of tropical cyclones are being monitored from the early stages of their formation. WMO coordinates activities in this area globally and regionally through the Tropical Cyclone Programmed. Within the framework of this program, regional meteorological centers specializing in tropical cyclones and tropical cyclone warning centers designated by the WMO operate. The role of these centers is to identify, monitor, track and forecast all tropical cyclones in their respective regions. These centers provide real-time guidance and warnings to the National Meteorological and Hydrological Services.

In a tropical depression, winds can reach speeds of 62 kilometers per hour (km/h), causing widespread flooding in areas and damage to infrastructure. Tropical storms have winds of 63 to 117 (km/h), torrential rain that can cause flooding and all kinds of damage. Sometimes they turn into tornadoes.

With this information, you will learn more about tropical cyclones and their characteristics.
