What process seems to weaken hurricanes?
As less moisture is evaporated into the atmosphere to supply cloud formation, the storm weakens. Sometimes, even in the tropical oceans, colder water churned up from beneath the sea surface by the hurricane can cause the hurricane to weaken (see Interaction between a Hurricane and the Ocean).
What is the intensity of the majority of tornadoes?
In the case of violent tornadoes, only a small portion of the path area is of violent intensity; most of the higher intensity is from subvortices. In the United States, 80% of tornadoes are rated EF0 or EF1 (equivalent to T0 through T3).
Which of the following is needed for a hurricane to form quizlet?
Three conditions required for hurricane formation are relatively high sea-surface temperatures, Adequate Coriolis Effect and weak winds aloft.
Which region of the United States experiences the greatest annual number of thunderstorms?
The most frequent occurrence is in the southeastern states, with Florida having the highest number ‘thunder’ days (80 to 105+ days per year).
What makes a hurricane stronger?
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. … And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes.
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.
What is tornado damage?
The damage from tornadoes comes from the strong winds they contain and the flying debris they create. … Wind speeds that high can cause automobiles to become airborne, rip ordinary homes to shreds, and turn broken glass and other debris into lethal missiles.
What type of damage would be expected in a tornado that has a wind speed of 152 mph?
Thus, the estimated winds would be 127 – 178 mph with the expected wind speed of 152 mph. Now, taking this number to the EF-Scale, the damage would be rated EF-3 with winds between 136 – 165 mph.
What is the weakest type of hurricane?
Category 1 hurricanes are the weakest, and 5’s the most intense. Hurricanes strong enough to be considered intense start at category 3 or with sustained winds exceeding 96 knots (111 mph).
Why can a hurricane cause so much destruction quizlet?
Why? The thing that causes the most damage is the flooding from the storm surge and the inland river flooding because it can flood anything underground and cause immense damage. The height of the water and the amount of things the water damages makes it the most costly.
Why do hurricanes weaken as they move over land?
Wind speeds up to 150 mph. Once a tropical system moves inland, the storm will usually weaken rapidly. This is due to the lack of moisture inland and the lower heat sources over land. … While the sustained winds are reduced because of the dampening effect of larger roughness over land.
Which state has the worst thunderstorms?
Here’s a look at the top 10 most thunderstorm-prone cities in the U.S., along with their average number of annual storms:
- Gainesville, Florida – 81.
- Orlando, Florida – 80.
- Mobile, Alabama – 79.
- West Palm Beach, Florida – 79.
- Lake Charles, Louisiana – 76.
- Daytona Beach, Florida – 75.
- Vero Beach, Florida – 75.
Where are the worst thunderstorms in the world?
The area that experiences the most thunderstorm days in the world is northern Lake Victoria in Uganda, Africa. In Kampala thunder is heard on average 242 days of the year, although the actual storms usually hover over the lake and do not strike the city itself.
Where do hurricanes occur?
Hurricanes originate in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, the eastern North Pacific Ocean, and, less frequently, the central North Pacific Ocean.
