Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph or less. Tropical Storm: A tropical cyclone with maximum sustained winds exceeding 3973 mph. Hurricane: Tropical cyclone with maximum winds exceeding 74 mph. Major Hurricane: Tropical cyclone with maximum winds exceeding 111 mph.
What are the 4 categories of a tropical cyclone?
Meteorologists have divided the development of a tropical cyclone into four stages: tropical disturbance, tropical depression, tropical storm and full tropical cyclone. When water vapor from the warm ocean condenses into clouds, it releases its heat into the air.
What are the 4 stages of tropical cyclone formation?
Classification. There are two types of cyclones: tropical cyclones and. Extratropical cyclones (also known as moderate or mid-latitude cyclones, or frontal cyclones or wave cyclones).
How many types of tropical cyclones are there?
These classifications are tropical depression, tropical storm, typhoon, and super typhoon.
What categories of cyclones are there?
atmospheric instability, high humidity in the lower to mid-tropospheric levels, Coriolis force sufficient to develop a pre-existing low-pressure center, low-level focus or disturbance, and weak vertical wind shear.
What are the four 4 conditions for tropical cyclone formation?
atmospheric instability, high humidity in the lower to mid-tropospheric levels, Coriolis force sufficient to develop a pre-existing low-pressure center, low-level focus or disturbance, and weak vertical wind shear.
How is a cyclone formed step by step?
The average life cycle of a cyclone is nine days and includes four stages: formation, immaturity, maturity, and decay. The formation step is the first and develops from an area of strong convective clouds. The second stage (the immature stage) sees the onset of strong winds and the official naming of the cyclone.
What are the 4 types of tropical cyclones?
The fuel for a tropical cyclone is provided by the transfer of water vapor and heat from the warm ocean to the air above, primarily through evaporation from the sea surface. As warm, moist air rises, it expands and cools, becoming saturated quickly and released latent heat by condensation of water vapor.

What types of tropical cyclones are there?
TROPICAL STORM (TS) a tropical cyclone with a maximum wind speed of 62-88 km/h or 34-47 knots. SEVERE TROPICAL STORM (STS), a tropical cyclone with a maximum wind speed of 89-117 km/h or 48-63 knots. TYPHOON (TY) a tropical cyclone with a maximum wind speed of 118 to 220 km/h or 64,120 knots.
How many types of cyclones are there?
There are two types of cyclones: tropical cyclones and. Extratropical cyclones (also known as moderate or mid-latitude cyclones, or frontal cyclones or wave cyclones).
What is the 5th Tropical Cyclone?
The five systems are Hurricane Paulette, Hurricane Sally, Tropical Storm Teddy, Tropical Storm Vicky, and Tropical Depression Rene. Hurricane Paulette hit Bermuda early Monday morning.
How many tropical cyclones have there been?
Here is a list of tropical cyclones by year. Since the year 957 at least 12,791 tropical or subtropical cyclones have been recorded in the Atlantic, Pacific and Indian Oceans, the so-called basins.
