Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called “hurricanes.” Whatever they are called, tropical cyclones all form the same way. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator.
Where do tropical cyclones usually occur?
They form over warm oceans and can wreak havoc when they approach the shore. As the name suggests, tropical cyclones and hurricanes occur in the world’s tropics.
Why do tropical cyclones occur?
Tropical cyclones are formed only over warm ocean waters near the equator. When warm, moist air over the ocean rises upward from near the surface, a cyclone is formed. When the air rises up and away from the ocean surface, it creates an area of lower air pressure below.
What are the 4 types of tropical cyclone?
Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39-73 mph. Hurricane: A tropical cyclone with maximum winds greater than 74 mph. Major Hurricane: A tropical cyclone with maximum winds greater than 111 mph.
Which is the strongest among the three tropical cyclones?

What is tropical cyclone in simple words?
Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain. … Tropical cyclones are known by various names in different parts of the world.
What are the characteristics of a tropical cyclone?
Tropical Cyclone Characteristics
- Hurricane force winds generally extend out about 100 km (60 miles) from the centre.
- Storm force winds may extend out as much as 500 km (300 miles)
- Maximum wind speeds between 12 and 50 km from centre.
What is the largest part of a tropical cyclone?
Answer: The main parts of a tropical cyclone are the rainbands, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern in the northern hemisphere (clockwise in the southern hemisphere), and out the top in the opposite direction.

What are the classification of tropical cyclone?
TROPICAL STORM (TS) – a tropical cyclone with maximum wind speed of 62 to 88 kph or 34 – 47 knots. SEVERE TROPICAL STORM (STS) , a tropical cyclone with maximum wind speed of 89 to 117 kph or 48 – 63 knots. TYPHOON (TY) – a tropical cyclone with maximum wind speed of 118 to 220 kph or 64 – 120 knots.
Where is the tropical depression?
Tropical Depression 5 is located east-southeast of the Windward Islands and has picked up speed, moving west near 23 mph. The system is expected to move even faster in a west-northwest motion over the next 24 to 36 hours.
