As with all low pressure systems the winds of a tropical depression rotate counterclockwise if it is in the northern hemisphere and clockwise if it is in the southern.
In the Northern Hemisphere, winds in a tropical depression rotate counterclockwise. In the Southern Hemisphere, they rotate clockwise. This rotation is due to the Coriolis effect caused by the Earth's rotation.
Yes. A tropical storm has sustained winds of 39-73 mph. A tropical depression has winds of less than 39 mph.
A tropical depression has winds under 39 mph.
No. A tropical depression is a tropical cyclone with winds under 39 mph. A tropical storm is a tropical cyclone with winds from 39 mph to 73 mph.
The progression of increasing strength is: Tropical depression (under 39 mph winds) Tropical storm (39-73 mph winds) Hurricane (winds 74 mph or higher)
If sustained winds reach or exceed 39 mph, a tropical depression becomes a tropical storm.
A tropical depression is a tropical cyclone with sustained winds under 39 mph. A tropical storm one with sustained winds from 39 mph to 73 mph. A hurricane is a tropical cyclone with sustained winds of 74 mph or greater.
There is no lower limit for tropical depression winds, which go up to 38 mph.
A tropical depression becomes a tropical storm when sustained winds reach or exceed 39 mph.
Simply one of strength. When a tropical cyclone has sustained winds under 39 mph it is a tropical depression. When a tropical cyclone has sustained winds from 39 mph to 73 mph it is s a tropical storm. When a tropical cyclone has winds of 74 mph or higher it is a hurricane.
A tropical depression is a relatively weak tropical system, with sustained winds less than 39 mph. A hurricane is a powerful tropical system wind winds of at least 74 mph.
A tropical depression has sustained winds of 38 mph or less.
