What are the 5 categories of tropical cyclone?

Tropical cyclone categories explained

• Category one (tropical cyclone) Negligible house damage.
• Category two (tropical cyclone) Minor house damage.
• Category three (severe tropical cyclone) Some roof and structural damage.
• Category four (severe tropical cyclone)
• Category five (severe tropical cyclone)

What is the criterion used to categorize the tropical cyclones?

According to the National Hurricane Center, “a tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation.” Based on the maximum sustained wind speed (i.e., the Saffir–Simpson scale), tropical cyclones are …

How do you measure the severity and categories of a cyclone?

The Saffir-Simpson Hurricane Wind Scale consists of a five point scale of hurricane intensity and starts at 74 mph. Tropical cyclones with wind speeds up to 38mph are classified as tropical depressions and those with wind speeds from 39 – 73 mph are classified as tropical storms.

What is a Level 5 cyclone?

Scientists rank hurricanes from one to five on what is called the Saffir-Simpson Hurricane Wind Scale. Category 5 storms have sustained winds of at least 157 miles (252 kilometres) per hour.

What’s a category 5 typhoon?

Category 5 hurricanes are tropical cyclones that reach Category 5 intensity on the Saffir–Simpson hurricane scale. They are by definition the strongest hurricanes that can form on planet Earth. Landfalls by such storms are rare due to the generally westerly path of tropical cyclones in the Northern Hemisphere.

What is difference between cyclone and depression?

As nouns the difference between cyclone and depression is that cyclone is a system of winds rotating around a center of low atmospheric pressure while depression is (lb) an area that is lower in topography than its surroundings.

What is a small cyclone called?

Small intense cyclones that to can surprise ships in the northern waters and are sometimes called Artic Hurricanes due to their resemblance of tropical hurricanes. A polar low forms over sea in subarctic areas without sea ice and normally north of the polar front.

How do you classify a storm?

They are classified as follows:

1. Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less.
2. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots).
3. Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.

How bad is a category 5 cyclone?

A Category 5 cyclone’s strongest winds are VERY DESTRUCTIVE winds with typical gusts over open flat land of more than 280km/h. These winds correspond to the highest category on the Beaufort Scale. Extremely dangerous with widespread destruction.

What are the types of cyclone?

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).

How is the severity of a tropical cyclone described?

The severity of a tropical cyclone is described in terms of categories ranging from 1 (weakest) to 5 (strongest) related to the maximum mean wind speed as shown in this table. Note: corresponding approximate wind gusts are also provided as a guide. Stronger gusts may be observed over hilltops, in gullies and around structures.

What are the winds of a Category 3 cyclone?

CATEGORY 3 (severe tropical cyclone) Some roof and structural damage. Some caravans destroyed. Power failures likely.A Category 3 cyclone’s strongest winds are VERY DESTRUCTIVE winds with typical gusts over open flat land of 165 – 224 km/h.These winds correspond to the highest category on the Beaufort scale, Beaufort 12 (Cyclone).

How much damage can a Category 5 cyclone do?

Needless to say, category five cyclones, with winds that reach upwards of 155 miles per hour in speed, can do a substantial amount of damage. With these storms, often they will be, both radically strong wind events, as well as many of these, bring hundreds of millions of dollars of personal property damage to an area.

Can a Category 1 hurricane be a super typhoon?

Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term “super typhoon” is used for tropical cyclones with sustained winds exceeding 150 mph.
