What is the difference between tropical and Extra-tropical cyclones Upsc?
Extratropical cyclones cover a larger area and can originate over the land and sea. Whereas the tropical cyclones originate only over the seas and on reaching the land they dissipate. The extratropical cyclone affects a much larger area as compared to the tropical cyclone.
What are the two types of cyclone and how do they differ?
Hurricanes and typhoons are the two types of tropical cyclone. Atlantic and Northeast Pacific are the regions where hurricanes are found. Whereas, in the Northwest Pacific, typhoons are found. A tropical cyclone is divided into 5 categories depending on the intensity and the wind speed.
What is the difference between tropical cyclones and Extra-tropical cyclones?
Tropical cyclones are hurricanes or tropical storms. Extratropical cyclones are winter storms, or typical low pressure areas. Take a look at the following time-series plots, and see if you can figure out whether the storm is tropical or extratropical.
What is the difference between a tropical storm and a tropical?
They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
What are the characteristics of tropical cyclone?
A tropical cyclone brings very violent winds, torrential rain, high waves and, in some cases, very destructive storm surges and coastal flooding. The winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Does temperate cyclones have an eye?
Temperate cyclone generally moves eastward, while tropical cyclone moves from east to west. Cyclone’s eye is a typical feature in case of tropical cyclone, while temperate cyclone have no such concept.
What are the 3 different names for tropical cyclones?
When they form in the Atlantic or Eastern Pacific Oceans, tropical cyclones are called hurricanes. In the western North Pacific, the same type of storms are called typhoons. And in the South Pacific and Indian Oceans, they are called cyclones. The Atlantic hurricane season lasts from June through November.
Why temperate cyclones are not destructive?
Wind velocity in temperate cyclones is comparatively low. Typical range: 30 – 150 kmph. Less destruction due to winds but more destruction due to flooding. Tropical cyclones are elliptical in shape.
Why tropical cyclones are named differently?
In general, tropical cyclones are named according to the rules at a regional level. It is important to note that tropical cyclones/hurricanes/typhoons are not named after any particular person. The names selected are those that are familiar to the people in each region.
What are 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.
