Why is it that every twenty years we manage to get snowless winters?

Question

I live in South Bend Indiana and in the year 1984 we did not recive any snow and 2007 almost repeats it self.

Answer 1

The weather and climate operates in cyclical patterns. Some years an area will get little to no snow, others they will have tons. The past couple of years we had brutal winters in my area, now we have a winter of little snow.

Answer 2

While I am by no means a climatologist, I know one of the major reasons for a warm, snowless winter in parts of the United States is El nino. If you don't know, El nino is a warming of the equatorial waters in the western pacific due to a weakening of trade winds in the pacific ocean. What this does is modify the jet stream over the U.S., which is a core of higher winds in the upper atmospher (approximately at 10,000 km). The modified jet stream acts to block cold canadian air from entering the the U.S., causing many of us to experience warmer than average winter weather.

Answer 3

History repeats itsself. Seriously though, the earth has cycles of warm and cold periods. Remember your earth sciences class?

Answer 4

global warming
