The changes in temperatures mean a high fishing season for Peruvian fishermen. In short, this creates a well-documented domino effect on global weather — including direct impacts on New England’s weather. With a possible La Nina potentially on the horizon, there are at least some hints that New England weather could be in for somewhat of a rollercoaster ride this year as a result of it. La Niña is known to have negative effects on the weather patterns of several parts of the world. La Niña is effectively the opposite of El Niño, indicated by prolonged periods of sea temperatures in the same region (2), and the effects stated above are generally reversed. Typically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years.

That’s because the polar jet stream tends to stay a bit further north during a La Nina winter, bringing in frequent waves of colder weather and snowfall.

A National Hurricane Center study found that hurricanes have a far better chance of having a direct landfall on the continental Untied States during non-El Nino years. It appears increasingly likely that La Nina conditions will develop in the central Pacific Ocean later this year, and that could have significant both short- and long-term impacts on New England’s weather later this year.

El Nino and La Nina, known as the ENSO cycle, tends to have a big (although varying) impact on weather, particularly during the winter months. La Nina refers to the periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific. This website uses cookies to improve your experience.

La Nina weakened last spring into early summer but began to show signs of strengthening again late this summer as negative temperatu… The newly-released National Oceanic and Atmospheric Administration (NOAA) outlook for this summer’s hurricane season gives a 60 percent chance of a more active hurricane season than average, and a lack of an El Nino is a big part of the reason why.

The extent of those impacts is not equal and it depends in part on the strength and severity of the La Nina. El Nino typically reduces Atlantic hurricane activity thru increases in vertical wind shear, especially in Caribbean pic.twitter.com/U8cLtf3V0V, — Philip Klotzbach (@philklotzbach) May 14, 2020.

La Niña, El Niño or the lack of either, known as the neutral phase, is only one large-scale forcing on the atmosphere. While hurricane track widely varies, more activity, of course, increases overall odds of impacts from a tropical system. No hurricane has directly made landfall on New England since Hurricane Bob in 1991, although a then-weakened Hurricane Irene lashed western New England in 2011 and Superstorm Sandy had big impacts on southern New England in 2012. In the shorter term, though, that could have an increased impact on the upcoming Atlantic basin hurricane season.
