What is cyclone in simple words?
In meteorology, a cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. Cyclones are also referred to as hurricanes and typhoons.
What are the types of cyclones?
There are two types of cyclones: Tropical cyclones; and. Extra Tropical cyclones (also called Temperate cyclones or middle latitude cyclones or Frontal cyclones or Wave Cyclones).
What are the 5 categories of cyclones?
This is the tropical cyclone category system as used by the Bureau of Meteorology:
- Category one (tropical cyclone) Negligible house damage.
- Category two (tropical cyclone) Minor house damage.
- Category three (severe tropical cyclone)
- Category four (severe tropical cyclone)
- Category five (severe tropical cyclone)
What are two types of cyclone?
In a cyclone, the air is rotating inwards counterclockwise (in the northern hemisphere) and are commonly associated with strong winds and severe weather. There are several types of cyclones and the two main types are the tropical cyclone and the extratropical cyclone.
What are the 3 types of tropical cyclones?
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.
What is a Class 2 cyclone?
Class 2 is issued so as to allow 12 hours of daylight before the occurrence of gusts of 120 km/h. Class 3 is issued in time to allow 6 hours of daylight before the advent of 120 km/h gusts. Class 4 is issued when gusts of 120 km/h have occurred and are expected to continue.
What are tropical cyclones Class 9?
What is a tropical cyclone? They originate and intensify over warm tropical oceans. These are ferocious storms that originate over oceans in tropical areas and move over to the coastal areas causing violent winds, very heavy rainfall, and storm outpourings.
What are the tropical cyclone structure?
Anatomy of a cyclone Tropical cyclones are compact, circular storms, generally some 320 km (200 miles) in diameter, whose winds swirl around a central region of low atmospheric pressure. The eyewall in turn surrounds the interior region, called the eye, where wind speeds decrease rapidly and the air is often calm.
Do all tropical cyclones have an eye?
Eye. The “eye” is a roughly circular area of comparatively light winds and fair weather found at the center of a severe tropical cyclone. There is little or no precipitation and sometimes blue sky or stars can be seen.
How do Cyclones look like?
Cyclones look like huge disks of clouds. They are between 10 and 15 kilometers thick. They are made of bands of storm clouds rolled into a spiral around a zone of very low pressure called the eye of the cyclone. Winds are drawn in toward the eye of the cyclone, but they cannot penetrate it.
Which part of the storm is the strongest?

Why does wind stop at night?
The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface. As a result of this difference in cooling ability, it doesn’t take long for the ground to become colder than the air above it.
