What is a cyclone in one line?
A cyclone is a general term for a weather system in which winds rotate inwardly to an area of low atmospheric pressure. Those with maximum sustained winds of 39 mph or higher are called tropical storms. When a storm’s maximum sustained winds reach 74 mph they are called hurricanes or typhoons.
What are cyclones examples?
The definition of a cyclone is a violent rotating windstorm. An example of cyclone is a tornado. (popular) The more or less violent, small-scale circulations such as tornadoes, waterspouts, and dust devils.
What are cyclones easy definition?
cyclone. [ sī′klōn′ ] A large-scale system of winds that spiral in toward a region of low atmospheric pressure. A cyclone’s rotational direction is opposite to that of an anticyclone. In the Northern hemisphere, a cyclone rotates counterclockwise; in the Southern hemisphere, clockwise.
What is cyclone short essay?
The cyclones are irregular wind movements that are characterized by closed air circulation around a centre of low pressure. The main cause of cyclone closed air circulations are the atmospheric disturbances and the Earth’s rotation which imparts a whirling motion to these disturbances.
What is a synonym for 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.
What are the two types of cyclones?
There are several types of cyclones and the two main types are the tropical cyclone and the extratropical cyclone.
What is cyclone causes?
The causes of cyclone are a continuous rise of hot air and filling of the gap by cool air around. This is mainly caused due to the rising of hot air, similar to cyclones. However, unlike in cyclones, the rapid and continuous rise in warm air causes the wind to move even faster, thereby causing thunderstorms.
Are cyclones natural disasters?
Cyclones – Natural Disasters – Earth watching. Cyclones, Hurricanes and Typhoons are powerful storms that have winds in excess of 119 kilometres per hour (74 MPH). On average there are between 80-100 of these storms each year, and while only a fraction of these approach land they can cause devastation once they do.
What does cyclone mean in science terms?
(Image credit: NOAA) A cyclone is a general term for a weather system in which winds rotate inwardly to an area of low atmospheric pressure . For large weather systems, the circulation pattern is in a counterclockwise direction in the Northern Hemisphere and a clockwise direction in the Southern Hemisphere.
What does the term “cyclone” mean?
Definition of cyclone. (Entry 1 of 2) 1a : a storm or system of winds that rotates about a center of low atmospheric pressure, advances at a speed of 20 to 30 miles (about 30 to 50 kilometers) an hour, and often brings heavy rain.
Is a cyclone like a tornado?
A cyclone is generally defined in meteorology as an area of closed, circular fluid motion rotating in the same direction as the Earth. A tornado is a violent rotating column of air that is contact with both the ground as well as a cumulonimbus cloud. To many people cyclones and tornadoes are the same thing. However, this is not true.
What is the origin of the word ‘cyclone’?
The word Cyclone is derived from a Greek word cyclos, meaning coiling of snake. Tropical cyclone is a deep low pressure area wherein the central pressure falls 6 to 8 hPa (hectopascal) from the surroundings.
