Tropical Depression

Tropical Depression Once a group of thunderstorms has come together under the right atmospheric conditions for a long enough time, they may organize into a tropical depression.

A tropical depression is an organized system of clouds and thunderstorms with a defined, closed surface circulation and maximum sustained winds of less than 17 metres per second (33 kn) or 39 miles per hour (63 km/h).

A tropical cyclone is the common name given for hurricanes, tropical storms, and tropical depressions together. The benefit of understanding tropical cyclone origination is a better understanding of later development.

Tropical depression (TD): A tropical cyclone with maximum sustained winds near the surface of less than 39 mph. Tropical Depressions are listed only with a number, not a name.

Tropical Depression - a tropical cyclone with winds equal to or less than 27 knots Tropical Storm - a tropical cyclone with winds stronger than 27 knots but less than 66 knots ...

tropical depression - A tropical cyclone with a closed wind circulation and maximum surface winds up to 17 m s-1 (34 knots).

Tropical Depression- A tropical cyclone with winds that do not exceed 38 miles per hour. Tropical Storm- A tropical cyclone with winds of 39-73 miles per hour. Trough- An elongated low-pressure system that generally stretches north and south.

Tropical depression A closed-circulation low pressure area of tropical origin with maximum sustained winds of less than 34 knots. Tropical storm ...

Tropical Depression Cyclones that have maximum sustained winds of surface wind speed (using the U.S. 1-minute average) is 33 kt (38 mph or 62 kph) or less. They are either located in the tropics or subtropics.

Tropical Depression - It's a low-pressure disturbance that forms over warm tropical ocean waters and produces winds of 38 m.p.h. or less. Trough - It's an elongated area of low pressure.

Tropical Depression Wind speed up to 33 knots (38 mph). Tropical Storm Maximum wind speed of 34 to 47 knots (39 to 73 mph) ...

Tropical depression A mass of thunderstorms and clouds generally with a cyclonic wind circulation of between 20 and 34 knots Tropical disturbance An organized mass of thunderstorms with a slight cyclonic wind circulation of less than 20 knots.

Tropical Depression A tropical cyclone in which the maximum sustained surface winds are 38 miles per hour (33 knots) or less.

Tropical Depression- Tropical mass of thunderstorms with a cyclonic wind circulation and winds near the surface between 23 mph and 39 mph.

TROPICAL DEPRESSION - A organized tropical cyclone with winds less than 38 MPH. Must have a full rotary circulation.

T1550 Tropical depression Any depression of tropical origin. Tropical disturbance with a maximum wind speed of less than about 34 knots (the criterion varies according to regional agreements between national weather services).

Tropical or Subtropical Depression Cyclones that have maximum sustained winds of 33 knots or less. These are referred to as low pressure systems in public advisories and statements. Tropical Disturbance ...

Tropical DepressionA tropical cyclone in which the maximum 1-minute sustained surface wind is 33 knots (38 mph) or less.

Depending on sustained surface winds, the system is classified as a tropical disturbance, a tropical depression, a tropical storm, or a hurricane or typhoon.

This term encompasses tropical depressions, tropical storms, hurricanes, and typhoons.

Tropical Depression: The beginning stage of a "Hurricane" with wind speeds of at least 39 mph or 63 km. Given a number. Example: Tropical Depression No. 1. Tropical Storm: A Tropical Cyclone having winds between 39 to 73 mph or 63 to 118 km.

The storm begins as a tropical depression, as anticlockwise circulation begins to develop around a rainy, deepening low-pressure area. When the winds exceed 33 kt, the tropical depression is promoted to tropical storm and is given a name.

When a storm develops a clearly recognizable pattern, it is referred to as a tropical depression. When wind speeds reach 35 knots (40.3 mph), it is called a tropical storm and is given a name.

As the winds increase they move through the states of tropical depression and tropical storm before becoming a hurricane.

A region of low atmospheric pressure that is usually accompanied by low clouds and precipitation. The term is also sometimes used as a reference to a Tropical Depression. Depression Storage ...

In meteorology, it is another name for an area of low pressure, a low, or trough. It also applies to a stage of tropical cyclone development and is known as a tropical depression to distinguish it from other synoptic features. DERECHO ...

special note are the occasions when tropical storms and/or hurricanes that did have names allotted, enter the area of interest. It is usual in these cases to allot the initial letter of the name to that depression, thus the extra-tropical depression ...

The term is also sometimes used as a reference to a Tropical Depression. Depression StorageIn hydrologic terms, the volume of water contained in natural depressions in the land surface, such as puddles.
