Quick Answer: What do you understand about the tropical revolving storm or TRS?

What is a weather TRS?

A tropical revolving storm or a TRS is a storm system with a low-pressure centre, around which winds of gale force (34 knots or force 8) or more blow spirally inwards, anticlockwise in the Northern Hemisphere (NH) and clockwise in the Southern Hemisphere (SH).

What makes a tropical revolving storm?

The Coriolis force caused by the rotation of the Earth causes the tropical storm to spin. The central part of the tropical storm is known as the eye. … Large towering cumulonimbus clouds surround the eye. These are caused by warm moist air condensing as it rises.

How is a TRS formed?

As the air rises quickly more warm moist air is drawn upwards from above the ocean creating strong winds. The rising warm air spirals upward and cools. The water vapour it carries condenses and forms cumulonimbus clouds. These cumulonimbus clouds form the eye wall of the storm.

Why do TRS recurve?

This is due to air currents in the local atmosphere that push cold air from the poles towards the equator and interfere with cyclone formation. That’s what make them ‘re-curving. ‘ In the southern hemisphere, the cyclones spin clockwise and therefore also re-curve in the opposite direction.

Why TRS does not form in South Atlantic Ocean?

Strong wind shear in the Troposphere, which disrupts the formation of these cyclones, as well as a lack of weather disturbances favourable for development in the South Atlantic Ocean (such as the tropical waves common the in the southern North Atlantic) make any strong tropical system extremely rare.

Which of the following is used to classify tropical storm categories?

Joint Typhoon Warning Center (JTWC) and other US meteorological organizations use Saffir-Simpson Scale to classify tropical storms stronger than the hurricane (or typhoon) intensity based on the maximum sustained wind (1-min mean).

How tropical cyclone affects navigation?

Despite their devastating effects, tropical cyclones are also beneficial, by potentially bringing rain to dry areas and moving heat from the tropics poleward. Out at sea, ships take advantage of their known characteristics by navigating through their weaker, western half.

What are factors which affect the movements of a TRS?

The factors which contribute to the intensity of a revolving storm are:

  • Instability. …
  • Humidity. …
  • Latitude. …
  • Temperature: Tropical revolving storms form over water surfaces with a water temperature of at least 27C.
