yes on mars, Jupiter, Saturn
Not really. While some of the other planets do have cyclonic storms, they are of a different nature from the hurricanes that occur on earth. It is possible that tropical cyclones (the generic term for a hurricane) occur on planets outside our solar system, but there is no way of observing if this is true with current technology.
No, hurricanes cannot collide with each other. When two hurricanes come close to each other, they typically rotate around a common center or merge into a single, larger storm.
No, hurricanes cannot collide with each other. If two hurricanes come close to each other, they will typically rotate around a common center or merge into a larger storm.
No, hurricanes do not collide with each other. If two hurricanes come close enough, they can interact in a process called the Fujiwhara effect, where they rotate around each other.
No. Hurricanes require liquid among other things. There is no liquid on Pluto.
Hurricanes and other tropical cyclones such as typhoons are just about the only storms that get names.
Yes.
Other storms that can cause wind damage like hurricanes include tornadoes and derechos
No, hurricanes do not collide with each other. Instead, they can interact in ways that influence each other's paths and intensities, but they do not physically collide.
The other planets are not similar to dwarf planets.
No. It's the other way around. Climate change can affect hurricanes.
The other planets do have gravity.
