WHAT IS TROPICAL
CYCLONE SEA STORM
A tropical cyclone, also known as a sea storm, is a rotating
low-pressure system that forms over tropical or subtropical waters. It is
accompanied by thunderstorms, high winds, and heavy rainfall. The system is
characterized by a closed circulation around a center of low pressure, with
wind speeds exceeding 74 miles per hour.
To understand a tropical cyclone and the process of its
formation and development, we will define the steps involved in a tropical
cyclone.
Step 1: Pre-Formation
A tropical cyclone requires specific atmospheric and oceanic
conditions to form. Warm ocean temperatures, high humidity, and low vertical
wind shear are necessary for its development. The waters must be at least 80°F
and extend to a depth of 150 feet or more. The low vertical wind shear prevents
the development of a weak tropical disturbance, and the high humidity provides
the necessary moisture for the storm. The pre-formation phase typically begins
with the formation of a tropical disturbance.
Step 2: Tropical
Disturbance Formation
A tropical disturbance is a cluster of thunderstorms that
develops over the ocean. The disturbance must be warm and moist, with
converging winds that cause the air to rise. This rising motion produces
thunderstorms, and the disturbance begins to organize as it continues to move
over the warm water. If the atmospheric conditions are favorable, the
disturbance may progress to the next stage of development.
Step 3: Tropical
Depression
A tropical depression is the intermediate stage between a
tropical disturbance and a tropical storm. It is characterized by a
low-pressure center, rotating winds, and a circular wind pattern. The
depression produces sustained winds of up to 38 miles per hour. Thunderstorms
also become more organized, and the depression becomes better defined. It is at
this stage that the depression is assigned a name.
Step 4: Tropical
Storm
A tropical storm is a more intense system than a depression.
The sustained winds of a tropical storm range from 39 to 73 miles per hour. The
storm continues to produce thunderstorms, heavy rainfall, and gusty winds. The
system gets a name when it develops into a tropical storm. During this phase,
the circulation of the storm tightens, and a characteristic eye begins to form.
Step 5: Hurricane
If a tropical storm continues to intensify, it may reach
hurricane status. A hurricane is characterized by sustained winds that exceed
74 miles per hour. The storm also has a more defined eye, with the winds moving
in a counterclockwise motion. Hurricanes are classified based on their wind
speeds on the Saffir-Simpson Hurricane Wind Scale, a 1-5 scale with 5 being the
most severe. Category 5 hurricanes have wind speeds in excess of 157 miles per
hour.
Step 6: Decay and
Dissipation
A tropical cyclone typically lasts from three days to two
weeks. Once the storm moves over land or cooler ocean water, the system will
begin to weaken. The diminished fuel source of warm water and a lack of
instability in the atmosphere will cause the storm to lose strength. The final
stage of the storm is dissipation, where the low-pressure center dissipates,
and the remaining thunderstorms and rainfall are absorbed by the environment.
A tropical cyclone is a powerful and hazardous natural
disaster that can cause significant damage to coastal communities.
Understanding the process of formation and development can help authorities and
individuals respond appropriately, minimize damage, and safeguard lives.
