Global climate abnormalities of La Niña are less pronounced and in some areas tend to be the opposite of those associated with El Niño. Odds of #ElNino for peak of Atlantic #hurricane season (August-October) have dropped from 22% (with early April forecast) to 10%, per the latest outlook from NOAA.
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. National Weather Service forecast models and official Climate Prediction Center (CPC) prognostications are indicating an increased probability of cooler-than-average sea-surface temperatures in the central-eastern Pacific Ocean this fall and winter.
It’s still far too early to tell how strong it might be, if a La Nina even develops. In short, this creates a well-documented domino effect on global weather — including direct impacts on New England’s weather. However, in Peru, things are different.
La Niña is known to have negative effects on the weather patterns of several parts of the world. In the shorter term, though, that could have an increased impact on the upcoming Atlantic basin hurricane season. The extent of those impacts is not equal and it depends in part on the strength and severity of the La Nina.
Last week, the CPC increased the odds of a La Nina developing this winter up to 45 percent — and lowered the odds of an El Nino event to just 10 percent. However, while certain events and impacts are expected to occur during events, it is not certain or guaranteed that they will occur. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle. La Nina refers to the periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific. The changes in temperatures mean a high fishing season for Peruvian fishermen.
Council should vet judge candidate Harnais. 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. The Effects of La Niña: Changes in global atmospheric circulation patterns accompany La Niña and are responsible for weather extremes in various parts of the world that are typically opposite to those associated with El Niño. La Niña’s effects on global weather include droughts in the eastern equatorial Pacific and floods in the western equatorial Pacific. 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.
