UNITED STATES, WASHINGTON (OBSERVATORY) — Hurricane Durian is now sweeping through the Bahamas and heading across America’s east coast, destroying Florida’s most popular tourist destination.
Durian began as a tropical storm, but turned into a very powerful Category 5 hurricane on a five-scale scale, raising the common question about the differences between tropical storm, typhoon and typhoon.
Typhoons, tropical cyclones and typhoons all point to the same weather phenomenon, but what makes a difference is where they are located. Typhoon is born over the Pacific Northwest.
– Tropical cyclone:
It is also known as a tropical cyclone, or Hurricane, a tropical storm that forms over the North Atlantic and northeast Pacific.
Tropical cyclones form north of the equator and rotate counterclockwise due to Earth’s rotation. Its direction is reversed in the southern hemisphere.
These hurricanes are characterized by a low pressure center and a large number of thunderstorms that lead to strong winds, heavy rains and floods.
Tropical cyclones arise when warm water evaporates from the ocean and rises up in steamy air. This creates a system of low pressure that absorbs air from the surrounding areas, thus causing the ocean to warm.
When steam rises, it cools and condenses into the cumulative cloud ranges. This system grows and circulates faster, absorbs more air and feeds energy into the sea water heated by the sun.
In the middle, a quiet “eye” arises from the storm, where cold air sinks toward the extremely low pressure zone below, surrounded by rising winds of warm air.
The higher the wind speed, the lower the air pressure in the middle and the storm becomes stronger and stronger.
Tropical cyclones usually weaken when they hit land because they are no longer fed by evaporation from the warm sea.
A tropical storm can turn into a hurricane when low air pressure absorbs above sea level above normal, and can flood low coasts if it coincides with high tides.
