Which continent has the highest number of tornado occurrences?
Tornadoes can form anywhere in the world and so far have been detected in every continent except Antarctica.
However, the highest frequency of tornado incidences is in North America in the so-called Tornado Alley region of the United States..
What causes storm clouds to develop?
Moisture in the air is also responsible for making clouds. Unstable air forms when warm, moist air is near the ground and cold, dry air is up above. … As the air lifts higher and higher, it causes a storm cloud to grow taller and taller. Thunderstorm clouds can rise up to 10 miles into the air!

Cumulus StageThe Mature Cumulus Stage This is the most dangerous stage when tornadoes, large hail, damaging winds, and flash flooding may occur.
How fast do thunderstorms move?
The speed of isolated storms is typically about 20 km (12 miles) per hour, but some storms move much faster. In extreme circumstances, a supercell storm may move 65 to 80 km (about 40 to 50 miles) per hour.
How do you calm down during a thunderstorm?

Why do most thunderstorms happen at night?
Thunderstorms that form at night occur in the absence of heating at the ground by the sun. Consequently, the storms that form at night are usually “elevated,” meaning that they form aloft above the cooler air near the ground, rather than near the ground, which only during the day can get warmer.
Which two states have the highest number of tornadoes per year per 10000 sq miles?
Florida has 12.3 tornadoes per 10,000 square miles to lead the list. Alabama has 8.6 tornadoes per 10,000 square miles. Kansas is No. 2 on the list, followed by Maryland, Illinois and Mississippi.
What are the three stages of thunderstorm development?
Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage. The developing stage of a thunderstorm is marked by a cumulus cloud that is being pushed upward by a rising column of air (updraft).
How long do severe thunderstorms last?
Thunderstorms, lightning and hail: Thunderstorms and lightning occur throughout Canada but less frequently in the North. On average, 10 people die each year in Canada and up to 160 are injured during such storms. Thunderstorms are usually over within an hour, although a series of thunderstorms can last several hours.
What is the third stage of a thunderstorm?
Discussion: There are three stages of a thunderstorm: the cumulus stage, the mature cumulus stage, and the dissipating stage. Each stage are defined by certain characteristics and are outlined below. Air that is warmer than its environment will start to rise by convection during this stage.
How do you know when a thunderstorm is ending?
After you see a flash of lightning, count the number of seconds until you hear the thunder. (Use the stop watch or count “One-Mississippi, Two-Mississippi, Three-Mississippi,” etc.) For every 5 seconds the storm is one mile away. Divide the number of seconds you count by 5 to get the number of miles.
What was the longest lasting thunderstorm?
SupercellsSupercells are powerful thunderstorms which form around a mesocyclone, a deep, rotating updraft. At up to several kilometres across, they can last several hours, making them the longest-lasting and largest of all thunderstorms. They often occur on the Great Plains of the USA and can spawn tornadoes.
Can planes take off in thunderstorm?
Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so enroute flights always seek to go around them. … Flights avoiding New York area weather-impacted airspace on September 11, 2013.

Why are thunderstorms so common quizlet?
warm, moist air, so they are most prevalent in regions with maritime Tropical (mT) air masses and in regions where mountains and frontal cyclones help lift air vertically. … or the change of environmental wind speed and direction from the ground up, is another factor affecting thunderstorm type.
Which best defines a thunderstorm cell?
Which best defines a thunderstorm cell. a single individual thunderstorm consisting of an updraft and downdraft. what is a long-lived, straight-line wind produced by strong downbursts from an intense thunderstorm.
What is the range of wind speed associated with EF 3 tornadoes quizlet?
