There is no real evidence that the number of cyclones or tornadoes is increasing outside of normal fluctuation. The apparent number has increased as advanced technology has made us better able to detect and identify storms, and fast communications means we hear about more events sooner.
Many hurricanes have produced tornadoes, it is a fairly common ocurrence. Most hurricanes that have hit the United States in recent years have produced tornadoes.

Tornadoes are sometimes called twisters. When hurricanes occur in other parts of the world may be called typhoons, cyclones, or severe cyclonic storms. The generic term for a hurricane is tropical cyclone.

Not officially, but in recent years a rice in Tornadoes (up to 200 a year) means that Autumn/Fall is the season for Tornadoes!
No. recently. In recent years astronomers have observed magnetic vortices on the sun that have been informally dubbed "solar tornadoes" but they are not actual tornadoes and are driven by different mechanisms from tornadoes on Earth.
As cities grow, they become bigger targets. There are more neighborhoods that tornadoes can hit. Tornadoes of recent years have struck neighborhoods that were open country 20 years ago.

Yes. It it fairly common for hurricanes to produce tornadoes when they make landfall. Therefore, any state that can get a hurricane could get a hurricane-spawned tornado. Some states, notably in the far northwest, will rarely if ever be affected by either tropical cyclones or by tornadoes, because the weather systems there are not conducive to their formation. The state of Alaska has had only 2 confirmed tornadoes over the last 65 years and only post-tropical cyclones.

There is no way of saying for certain. The apparent increase in tornado activity over the past 60 or so years is due largely to our improved ability to detect and confirm weaker tornadoes. U.S. statistics for stronger tornadoes show no overall increase in activity.
Since data is incomplete for 2014, we will use the most recent 20-year period of 1994-2013. During this time there were 496 recorded tornadoes in Indiana.
Tornadoes are detected using Doppler weather radar. In recent years some of these radars have been upgraded with dual-polarization to further aid in detectng hail and tornadic debris.
