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.
