After about one year of forecast, the climate phenomenon dubbed as El Niño is here once more, according U.S. climate researchers. The signs announcing its arrival are hotter than-typical ocean temperatures along a part of the central Pacific that can have a critical effect on climate around the globe, bringing additional rain in a few areas and dry spell in others. In Maryland for instance, its effect can fluctuate, however it is connected with snowy winters and less Atlantic storms.
Circumstances in the Pacific have hinted the development of El Niño since last spring. In May, climatologists anticipated 90 percent risks the pattern would start by the fall of 2014. Howeve, even if the Pacific waters warmed up, other climate conditions were at the time not characteristic of El Niño.
Until now, the phenomenon is viewed as a “frail” El Niño, Mike Halpert, deputy executive of the Climate Prediction Center in College Park, commented for the Associated Press. That could imply fewer significant effects.
Also, this El Niño will not contribute much to inverting the ongoing dry season in California, as expected, because it will start toward the end of that area’s rainy season, Halpert added.
This is the planet’s first El Niño since March 2010. Since then, there have been two events of La Nina, a connected phenomenon linked to cool waters in the Pacific from June 2010 to March 2011 and August 2011 to February 2012.
Be that as it may, for most of the last three years , the world has been under “impartial” conditions, with neither an El Niño or a La Niña.
El Niño’s effect on Maryland can be hard to anticipate. The area’s position between mountains and sea, with the Chesapeake Bay in the center, keeps significant climate variations away.
It does relate with cold winters, however. While around 18-20 inches of snow falls in a normal winter in Baltimore, about 27 inches fall in an El Niño year, as per an investigation by the National Weather Service’s Baltimore/Washington forecast office.
The record 77 inches of snow that fell in winter 2009-2010, for instance, came amid a temperate El Niño, the last one to happen. However, the second-snowiest Baltimore winter, 62.5 inches in 1995-1996 came amid La Niña, known for mellow winters there.
Obviously, this El Niño is popping in late in the season to have a lot of an effect on snowfall. Whether this El Niño will continue through next winter is difficult to accurately forecast.
