They don't. Tornadoes do occur in New York, but they are relatively rare. The regions cool climate and less-than ideal setup of wind shear and instability means that tornadoes, especially strong ones, don't occur often.
There are several factors. First, New York has a relatively cool climate and as a result the atmosphere tends to be more stable and less prone to the severe thunderstorms needed to produce tornadoes. In addition, the fronts that occur are often not strong enough to produce tornadic thunderstorms and more often produce squall lines, which often produce damaging winds but not tornadoes. Wind shear is also not as strong there and strong wind shear is needed for the right kind of thunderstorm called a supercell.
Tornadoes form from powerful thunderstorms that need a large amount of energy in the atmosphere. This energy is available when the air is very warm and moist. New York has a relatively cool climate and often does not have the energy necessary. Additionally, wind sheer (changes in wind speed and direction with height) over New York favors thunderstorms to form squall lines, while tornadoes form most easily in supercells.
Yes. New Jersey has had tornadoes as strong as F3.
On average, New Zealand experiences 20 tornadoes per year.
Tornadoes do not get actual names. Tornadoes are usually referred to by where they occur, most often a town that they hit or go near.
Yes. Both New York State and New York City have had tornadoes.
Eventually, yes. New York, both the state and the city, get tornadoes. However, there is no way of known when these tornado will happen.
There were 2 tornadoes in New York in 2008.
Yes. The State of New York has had tornadoes as strong as F4, and New York City has had a few tornadoes as well.
Not really. While tornadoes do occur in New York, strong tornadoes are rare and deaths are even less common.
Yes. The states of New York gets a few tornadoes each year, most of them weak. New York City has also had a few tornadoes, at least one of which was a killer.
Yes, all 50 states have had tornadoes. New York averages 5 each year.
they occur mostly in new york. they could happen anywhere
There were 8 recorded tornadoes in New York in 2012.
Tornadoes have occurred in New York, both the city and the state. Most have been weak. These tornadoes have brought down trees and damaged homes and buildings, occasionally destroying them. Some have resulted in deaths and injuries. No single tornado in the state of New York has killed more than four people. Only one person in New York City has been killed by a tornado.
It is inevitable that eastern New York will see tornadoes eventually, but currently, as of late October 2012 the risk of tornadoes is negligible. The main threat facing New York is Hurricane Sandy.
