It depends on atmosphere conditions, but they begin to dissipate right away, mostly gone in about 15 or 20 minutes, but can last longer on a still day.
in one minute the earth spins 28km, so it spins 420km in 15 minutes
If you're talking about the basic water cycle, starting in the ocean, water evaporates into vapor (Evaporation) rising up until it reaches it's the dew point, then the water condenses and travel towards higher ground, sometimes it travels as far as sea level ground (Condensation), when it reaches that heavy point where the clouds is too heavy to carry the water it drops taking about 10-15 minutes from the clouds to reaches the surface of the Earth if clouds are in the strato zone (Precipitation).
According to some scientists publications the average speed of the earth rotation is about 30km/s, so 15 minutes has to be 27000km
It will last about 15 billion years
It is not uncommon for larger tornadoes to last longer, but not always. For example, the first of two tornadoes near Happy, Texas on May 5, 2002 had an extremely larger funnel, but lasted only about 15 minutes, while other, smaller tornadoes have lasted for over an hour.
