No, some form over the sea.
Thunderstorms over land can produce tornadoes, microburst or dust storm. Though all but the dust storm can form over water as well.
yes except Antarctica
No. A tornado that moves onto water will keep going without being significantly affected. In such a case it is called a waterspout. Waterspouts can also develop on water and then move onto land as tornadoes. There are numerous examples of tornadoes crossing water. Most notably, the three deadliest tornadoes in U.S. history all crossed the Mississippi River. See the links below for tornadoes moving across water.
Tornadoes are generally considered a land based phenomenon. There are however waterspouts which are essentially tornadoes on water, though they are generally not counted as tornadoes unless the hit land.
they can be found all over the earth except Antarctica Hurricanes specifically form over tropical ocean waters.
Yes. All tornadoes form in thunderstorms.
Yes, tornadoes can happen almost anywhere that there are thunderstorms.
If you can get thunderstorms, you can get tornadoes. However, even if tornadoes are possible in Egypt they, in all likelihood, very rare and any tornadoes that you do get will probably cause only minor damage.
All tornadoes form in thunderstorms and so are typically accompanied by thunder and lightning.
No. Many tornadoes form in a rain-free portion of their parent thunderstorms. Some tornadoes form with low-precipitation supercells, which produce little or no rain.
Yes, tornadoes typically form from severe thunderstorms known as supercells. These storms are characterized by rotating updrafts known as mesocyclones, which can produce the conditions necessary for tornado formation. However, not all thunderstorms produce tornadoes.
There really isn't a difference between hurricanes and typhoons. They are two names for the same type of storm: a hurricane is one that occurs in the Atlantic ocean or in the Pacific ocean east of the International Date Line. A typhoon is one that occurs in the Pacific ocean west of the International Date Line. However a hurricane is very different from a tornado. A tornado is relatively small, usually not more than a mile wide. Tornadoes usually form over land and can last anwhere from a few seconds to about three hours. A tornado causes damage with wind and flying debris. Tornadoes form from thunderstorms that are usually part of a large-scale storm system. A hurricane is huge, usually hundreds of miles across, sometimes over a thousand. Hurricanes form over warm ocean water and weaken rapidly over land Most hurricanes last a few days. Hurricanes cause damage through a combination of wind, debris, flooding from rain and storm surge, and large waves. A hurricane is itself a large storm system.
