A tropical storm is a tropical cyclone that has maximum sustained surface winds ranging from 39-73 mph (34 to 63 knots). A hurricane is a tropical cyclone that has maximum sustained surface winds of 74 mph or greater (64 knots or greater) .
What's the difference between a hurricane and a storm?
A hurricane is a very intense tropical weather system that rotates in a large circular formation. A category 1 storm has lower wind speeds, while a category 5 hurricane has the highest wind speeds .
What separates a hurricane from a tropical storm?
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 is the difference between a tropical storm and a hurricane quizlet?

What makes a storm a hurricane?
Those with maximum sustained winds of 39 mph or higher are called tropical storms. When a storm's maximum sustained winds reach 74 mph , it is called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating, or category, based on a hurricane's maximum sustained winds.
What is the difference between a tropical storm and a thunderstorm?
A tropical depression forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. An upgrade to a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust between 39 mph and 73 mph .
What are some differences between a hurricane tropical depression and a tropical storm?
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).

definition of a hurricane. an intense tropical cyclonic storm consisting of a warm-core low pressure ceel at its center, inward-spiraling rainbands, and having sustained winds in excess of 74 mph .
What are hurricanes called in the Indian Ocean?

In the northwestern Pacific, the same powerful storms are called “typhoons.” In the southeastern Indian Ocean and southwestern Pacific, they are called “ severe tropical cyclones .”
What is a hurricane short answer?

What are hurricane effects?
Hurricanes are one of nature's most powerful storms. They produce strong winds, storm surge flooding, and heavy rainfall that can lead to inland flooding, tornadoes, and rip currents .
How are hurricanes and thunderstorms similar?
What characteristic do thunderstorms, hurricanes, and tornadoes all share? They all form over dry and hot desert regions . They are all easily predicted by weather forecasters. They are all formed when warm and moist air rapidly rises.
What is the difference between a hurricane watch and a hurricane warning?
A hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds. Hurricane Warning: Issued to indicate that hurricane conditions (sustained winds of 74 mph or higher) are expected somewhere within the warned area.
How do hurricanes travel?
“Hurricanes almost always form over ocean water warmer than about 80 degrees F. in a belt of generally east-to-west flow called the trade winds. They move westward with the trade winds and also drift slowly poleward .
