What is the minimum wind speed of a tropical depression?
A tropical cyclone that has winds of
38 mph (33 kt) or less
is called a tropical depression. When the tropical cyclone’s winds reach 39-73 mph (34-63 kt), it is called a tropical storm. When the winds exceed 74 mph (64 kt), the storm is considered to be a hurricane.
What is the wind speed for a tropical depression quizlet?
As the air pressure drops and there are sustained
winds up to 38 mph
, it is called a tropical depression.
What is the maximum speed of tropical depression?

. It is a tropical storm when the maximum sustained wind speed is more than 63 km/h.
Does a tropical depression have an eye?
A typical tropical cyclone will have an eye of
approximately 30–65 km (20–40 mi) across
, usually situated at the geometric center of the storm. … A large ragged eye is a non-circular eye which appears fragmented, and is an indicator of a weak or weakening tropical cyclone.
How do tropical depression develop?
The storm begins as a tropical disturbance, which typically occurs when
loosely organized cumulonimbus clouds in an easterly wave begin to show signs of a weak circulation
. Once the wind speed increases to 36 km (23 miles) per hour, the storm is classified as a tropical depression.
Why is it called tropical depression?
As the heat energy is released from the cooling water vapor, the air at the top of the clouds becomes warmer, making the air pressure higher and causing winds to move outward away from the high pressure area. …
When the winds reach between 25 and 38 mph
, the storm is called a tropical depression.
What is a Category 5 cyclone?
Within the basin a Category 5 severe tropical cyclone is a
tropical cyclone that has 10-minute mean maximum sustained wind speeds over 107 knots (198 km/h; 123 mph) or greater on the Australian
tropical cyclone intensity scale.
How long do tropical storms last?
Hurricanes can often live for a long period of time — as much as
two to three weeks

Cyclones rarely form in other tropical ocean areas, which are not formally considered tropical cyclone basins.
Is a Category 1 hurricane worse than a Category 5?
To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph.
What are the 4 categories of tropical cyclone?
These classifications are
Tropical Depression, Tropical Storm, Typhoon, and Super Typhoon
.
Why is the eye of the storm the calmest?
Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. The eye is so calm
because the now strong surface winds that converge towards the center never reach it
. … This convergence causes the air to actually sink in the eye.
