What is tropical cyclone in simple words?
A tropical cyclone is a rapidly-rotating storm system characterized by a low-pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. The term “tropical” refers to the geographical origin of these systems, which usually form over the tropical oceans.
What is a tropical cyclone called?
In the southern hemisphere these tropical storms are called cyclones and rotate in a clockwise direction, while in the northern hemisphere cyclones are called hurricanes or typhoons and rotate in an anti-clockwise direction. …
What are tropical cyclones Class 9?
What is a tropical cyclone? 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 is a cyclone Class 10?
Cyclones are wind storms accompanied with heavy rainfall at low-pressure areas. They are caused due to a continuous process of rising of hot air over the ocean surface. However, a cyclone can be said to be more of a rotating or spinning wind. Contrarily, a thunderstorm may not always be spinning in nature.
What is tropical cyclone in geography?
A tropical cyclone is an intense low pressure system that is classified on the basis of its wind speed. The phenomena has a definitive structure and a well-defined life cycle. TCs occurring over the north Atlantic Ocean are known as hurricanes and those occurring over the Pacific are known as typhoons.
How do you explain a cyclone?
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 is cyclone explanation?
In meteorology, a cyclone (/ˈsaɪ. kloʊn/) is a large scale air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone).
What is a cyclone Class 9?
Cyclones is a small low pressure system winds blowing from the surrounding high pressure areas.It rises causing swirls in the atmosphere. It then cools off to form clouds.
What is a cyclone for Class 7?
A cyclone is a weather condition consisting of a system of high-speed winds revolving around a central area of very low pressure. Cyclones develop over tropical seas. It is a violent storm with a wind speed of 150-250 km/h.
What is called cyclone?
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.
What is a cyclone and how is it defined?
Tropical cyclones are low pressure systems that form over warm tropical waters. They typically form when the sea-surface temperature is above 26.5°C. Tropical cyclones can continue for many days, even weeks, and may follow quite erratic paths. A cyclone will dissipate once it moves over land or over cooler oceans.
