Answer to Question 1
ANSWER: It is a myth that larger cities such as Los Angeles, California, and New York City are somehow protected from tornadoes. On March 1, 1983, a rare tornado cut a 5-km swath of destruction through downtown Los Angeles, damaging more than 100 homes and businesses, and injuring 33 people. And during the summer of 2010, three tornadoes actually touched down in New York City. One tornado (on July 25) caused only minimal damage but injured seven people.
Answer to Question 2
ANSWER: About 70 percent of all tornadoes in the United States develop from March to July. The month of May normally has the greatest number of tornadoes (the average is about 9 per day), while the most violent tornadoes seem to occur in April, when vertical wind shear tends to be present as well as when horizontal and vertical temperature and moisture contrasts are greatest. Although tornadoes have occurred at all times of the day and night, they are most frequent in the late afternoon (between 3:00 P.M. and 7:00 P.M.), when the surface air is most unstable; they are least frequent in the early morning before sunrise, when the atmosphere is most stable.
