Not usually. Tornadoes generally form on land. Kansas is one of the most tornado prone area in the world and it is nowhere near the ocean.
Hurricanes can only develop over warm ocean water. Tornadoes can form on water but usually form on land.
When a storm spawns a tornado it produce a tornado.
Cumulonimbus
A tornado is typically spawned from a supercell thunderstorm cloud, known as a mesocyclone. These types of clouds are characterized by a rotating updraft, which can produce the necessary conditions for tornado formation.
Yes, in some instances one tornado may spawn a smaller satellite tornado.
A tornado warned storm is a thunderstorm for which a tornado warning has been issued, meaning that the storm is producing rotation that can spawn a tornado.
A large, intense tornado can sometimes spawn a second smaller tornado that circles it and is called a satellite tornado.
If you mean to ask if one tornado can form after another has dissipated, yes. Supercells, the storms most likely to produce tornadoes, often go through cycles. They can spawn can spawn multiple tornadoes one after another in what is called a tornado family.
A tornado on water is called a waterspout.
Salmon live in the ocean, but swim up rivers to spawn.
Tornadoes generally form over land, not the ocean. You are thinking of hurricanes. The term hurricane refers to a tropical cyclone that occurs over the Atlantic Ocean or the eastern Pacific ocean.
If you mean to ask if one tornado can form after another has dissipated, yes. Supercells, the storms most likely to produce tornadoes, often go through cycles. They can spawn can spawn multiple tornadoes one after another in what is called a tornado family. Sometimes the next tornado in the family will form before the current one has dissipated, resulting in there being two tornadoes at the same time.
