La Nina's Effects on the East Coast?

Question

We had a terribly warm Winter last year. It stayed in the mid 50s and upper 60s throughout November and December(It was awkward sweating while putting up Christmas Lights).

I'm aware that El Nino causes warmer than usual temperatures, but what about Nina? What effects will it have this year on the East Coast?.

Answer 1

If I answered it would have a certain effect, or it would have no effect, I'd be lying. The truth is no one knows for sure, primarily because El Nino/La Nina are not the only controlling factors of longer-term weather (called "climate"). There are other factors...one in particular that affects the East Coast and New England is something called the "North Atlantic Oscillation" or NAO. It is based on pressure readings over the Azores and Iceland. The phase of the NAO effects whether you have lower pressure and generally cooler weather over the northeastern U.S., or have higher pressure and warmer weather there.

La Nina usually brings colder than normal winter weather over the eastern U.S., but that can be tempered by the NAO phase if it favors higher pressure aloft and warmer temperatures. Likewise, a La Nina plus a negative phase of NAO that favors cold air outbreaks in the eastern U.S. yields a very cold winter. Unfortunately, the phase of NAO is only predictable a few weeks in advance, so it can't really be used to predict what next winter will be like.

The overall point: La Nina/El Nino can and likely do have some impact on weather, but are not the only factors at play (obviously if they were, long range forecasting would be easy). One final thing, the impacts of La Nina/El Nino on temperatures are felt most substantially during the winter season...with likely very little impact during the summer.

Hope this helps...more information on deadly weather, and how to use data on the Internet to anticipate/recognize it, can be found in a public education course I developed. More information can be found at http://www.storm-prep.com.

Answer 2

Overall, La Ninas tend to have the opposite effect an El Nino would have. Much of the effects have to do with the severity of the La Nina.

Overall, the east coast averages near to slightly below normal temperatures and near to below normal precipitation and snowfall.

This is just one of many influences on our weather; we can't take one factor as the cause of all our weather.

Answer 3

The El Niño ended in March this year. There is no indication at this stage that we are headed for a La Niña. The Southern Oscillation is between normal conditions and El Niño not netween El Niño and La Niña. La Niña is really just an accentuation of normal conditions, it doesn't have the same marked characteristics as an El Niño. You do not have to have a La Niña between successive El Niños and most often, you don't.

Answer 4

"l. a. Niña" ought to final for as much as two years and is linked with an boost in Atlantic hurricanes. it truly is probable to realize height intensity in December to February and then start to weaken next March to would. as a result 7 hurricanes are predicted for this season.
