Why do waterspouts form in singapore and how do they form?

Question

Waterspouts are similar to tornadoes aren't day?

Answer 1

Yes, a tornado touching a water surface is a waterspout.  However, the average wind speed found even in a large waterspout near the coast are usually not as strong as one of those classic land based column of cyclonic circulating wind that is also known as a tornado.  

Waterspouts usually form mainly due to strong low-level wind shear and at least a layer of instability found over the water surface.  However, many of these waterspouts are funnels that form over a much weaker convective cell.  And many are not associated with a thunderstorms unlike the classic ones you will more likely find in the inland areas.  These funnels seems to be more related to the known as cold air funnels, and maybe more associated with low level circulations or eddies found near the surface that are then partially lifted upwards with a developing updraft or convective circulation.  As these circulation are stretch upwards and toward the base of a moderate growing cumulus cloud or a towering cumulus cloud, the funnel speed increases as the diameter of the core circulation decreases.  This will increase the lift and you will likely end up with a waterspout that may or may not be associated with a thunderstorm.

Answer 2

Waterspouts are tornadoes that form over water. They are generally considered not as dangerous as tornadoes because there is no debris flying, but they can still be fatal.

Answer 3

A waterspout is a tornado but on the water.  They form anywhere where there's water.  Singapore has a lot of water around it (obviously) so that's why you would see them.  I have had them out here where I live too.

Answer 4

A waterspout IS a tornado, just over water.They both form the same way.
