What is the difference between a tropical depression and a tropical storm?
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).
How are tropical revolving storms formed?
Tropical storms form whenever sea temperatures rise above 27 °C and can be up to 650km across. They occur where the trade winds converge and often when the ITCZ has migrated to its most Northerly extent allowing air to converge or come together at low levels.
How are the wind speeds in a tropical depression different from the wind speeds in a tropical storm?
It is a tropical depression when the maximum sustained wind speed is less than 63 km/h. It is a tropical storm when the maximum sustained wind speed is more than 63 km/h.
What is a storm that develops from a tropical depression?
When the wind speeds reach 39 mph, the tropical depression becomes a tropical storm. This is also when the storm gets a name. The winds blow faster and begin twisting and turning around the eye, or calm center, of the storm.
How does typhoon differ from cyclone?
Called hurricanes when they develop over the North Atlantic, central North Pacific, and eastern North Pacific, these rotating storms are known as cyclones when they form over the South Pacific and Indian Ocean, and typhoons when they develop in the Northwest Pacific.
What does a tropical storm need to form?
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
What is the main energy source of a tropical revolving storm?
The fuel for a tropical cyclone is provided by a transfer of water vapour and heat from the warm ocean to the overlying air, primarily by evaporation from the sea surface. As the warm, moist air rises, it expands and cools, quickly becoming saturated and releasing latent heat through the condensation of water vapour.
What is the wind speed of tropical storm?
Tropical Storm: A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 34 kt (39 mph or 63 km/hr) to 63 kt (73 mph or 118 km/hr).
What is the difference among tropical depression tropical storm typhoon and super typhoon?
Tropical depression — the weakest tropical cyclone with maximum sustained winds of at least 61 kph. Tropical storm — has maximum sustained winds of 62 to 117 kph. Typhoon — has maximum sustained winds of 118 kph to 220 kph. Super typhoon — has maximum sustained winds of 220 kph and above.
What is tropical storm and its development?
tropical storm, organized centre of low pressure that originates over warm tropical oceans. If local atmospheric conditions support deep convection and low vertical wind shear, the system may become organized and begin to intensify. Intensification occurs as the air warmed at the surface begins to rise.
What’s the difference between a storm and a hurricane?
Wind speed is actually the only factor separating a tropical storm from a hurricane. For instance, a hurricane has to have sustained winds of 74 MPH or more, and a tropical storm can have sustained winds that are 73 MPH or less, according to the Weather Channel.
What are the winds of a tropical depression?
A tropical depression is a tropical cyclone that has maximum sustained surface winds (one-minute average) of 38 mph (33 knots) or less. A tropical storm is a tropical cyclone that has maximum sustained surface winds ranging from 39-73 mph (34 to 63 knots).
What makes a tropical revolving storm a revolving storm?
A tropical revolving storm may be defined as a roughly circular atmospheric vortex, originating in the tropics or sub tropics, where in the winds of gale force (34 knots or force 8) blow in spirally inwards (Anti-Clockwise in North Hemisphere and Clockwise in South Hemisphere.
What kind of wind speed does a tropical cyclone have?
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. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones.
What are the characteristics of a post tropical cyclone?
A class of post-tropical cyclone that no longer possesses the convective organization required of a tropical cyclone and has maximum sustained winds of less than 34 knots. A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones.
