About 44.4%. So mesocylones don't always mean tornadoes.
When a hurricane hits land the lower portions of the storm weaken faster than the upper portions. This creates rolling air called wind shear, which gets taken into the updrafts of thunderstorms in the outer regions of the hurricane, turning the storms into supercells with rotating updrafts called mesocyclones. The rotation in the mesocyclones then tightens and intensifies to form tornadoes. Aside from the source of the wind shear this process is essentially the same as how tornadoes are formed under other circumstances, only the storms are usually along a cold front.
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.
Tornadoes themselves do not produce precipitation, but the storms that produce them usually do. Tornadoes are often accompanied by rain and hail.
Sometimes a hurricane can produce tornadoes, but most tornadoes are not produced by hurricanes.
Isolated tornadoes are tornadoes that do not occur as part of a significant outbreak. A storm system with isolated tornadoes may produce a single tornado or a small number of tornadoes scattered across a large area.
Mesocyclones, the rotating updrafts of supercells, are responsible for producing the majority of tornadoes, including all of most destructive ones.
The tornadoes associated with squall lines are generally short-lived and weak, especially the spin-ups along the leading edge. Some squall lines can have embedded mesocyclones, however, which can produce stronger tornadoes. In some cases a mesocyclone can develop at the north end of a bow echo and behave in a very similar manner to that of a supercell. These too have the potential to produce significant tornadoes.
Although many hurricanes do produce tornadoes, they are not a necessary part of hurricanes.

Usually one tornado does not result in other tornadoes. Some strong tornadoes can produce a satellite tornadoes that orbit them, but this is not very common.
No. Only about 1% of thunderstorms produce tornadoes.
About 1% of severe thunderstorms produce tornadoes.
Many hurricanes, but not all, produce tornadoes. However, most tornadoes do not come from hurricanes.
Less than 1% of thunderstorms produce tornadoes.
About 1% of thunderstorms produce tornadoes. That translates to about 1,000 tornadic storms each year.
In the United States about 1% of thunderstorms produce tornadoes.
No, hurricanes do produce floods but tornadoes do not, although the storms that produce them can.
