Wind speeds in tornadoes and thunderstorms vary widely. EF0 tornado winds officially begin at 65 mph, but tornadoes have been rated with winds estimated as low as 55 mph. At the other end, the most violent tornadoes may produce winds over 300 mph. There is no particular winds speed for a thunderstorm. Some produce no more than a breeze. A thunderstorm is classified as severe if it produces a gust to 58 mph or more. Aside from tornadoes, thunderstorms have produced winds to over 130 mph in rare cases. A tropical depression is defined as a tropical cyclone with sustained winds of less than 39 mph.
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.
A hurricane does not form from a single thunderstorm. A tornado does. Often a thunderstorm has upper-level rotation for at least half an hour or more before producing a tornado, however, some storms develop and become tornadic in less than 15 minutes.Hurricanes form from large, usually disorganized clusters of storms. It may take days for these clusters of storms to organize intro a tropical depression (tropical cyclone with winds under 39 mph). It will usually be several more days before such a system reaches hurricane strength (winds of at least 74 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.

No. A tropical storm is a large cyclonic storm system that forms over warm ocean water and produces winds from 39 to 73 mph. With further strengthening a tropical storm can become a hurricane. A tornado is a violently rotating column of air extending from the base of thunderstorm to the ground. Tornadoes are a very different phenomenon from tropical storms. First and foremost is that a tropical storm is its own storm system while a tornado is a relatively small vortex dependent on a parent thunderstorm. Additionally tornadoes usually form on land and are more common in temperate latitudes than tropical.
Strong and rotating updrafts within a thunderstorm create an area of low pressure at the surface. This low pressure draws in winds from the surrounding area, causing them to spin faster and form a tornado.
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.
Both are, but it is probably more likely with a tornado.
No, that would more likely be a hurricane or tropical storm. A tornado is a violently rotating column of air extending from the cloud base of a thunderstorm to the ground, often accompanied by a visible condensation funnel.
