Ohio is in the middle of December and are experiencing record temperatures. Last weekend, temperaturesΒ peaked in the mid 60s. The 2015 El NiΓ±o, or “little boy,” is hitting the country strong and could drasticallyΒ affect weather patterns across the country going into next year.
El NiΓ±o is a set of major weather changes. This term wasΒ originally used by fisherman to refer to a warm ocean current that usually appears around Christmas time and couldΒ last for several months. During the time of warm water intervals, fish are less abundant, the fisherman spend lessΒ time fishing and would often work on repairing equipment or spend more time with their families.
Over the years,Β the term βEl NiΓ±oβ has come to be reserved for these unusually strong warm water intervals that not only disrupt theΒ normal lives of fisherman but also bring heavy rain.
El NiΓ±o is caused by changing wind patterns over the Pacific Ocean that push unusually warm seawater eastward towards America. The warmth of the water shifts the flow of heat and moisture around the planet.
In El NiΓ±o conditions, the trade winds are weak and may even blow in theΒ opposite direction from normal. When this happens, warm surface water piles up near the west coast of SouthΒ America and colder water remains deep in the ocean causing more surface clouds to form over the warmer surface water.
This phenomenon affects weather patterns all over the world. Areas that typically see drought conditionsΒ experience extreme amounts of rain. Unusual temperatures changes, like Ohio saw last weekend, are seenΒ throughout the country.
El NiΓ±o events occur every three to five years. This year, the weather changes were noticed in March, and is the first event experienced since 2010. Scientists predict this could be one of the strongestΒ seen in decades. It has a 90 percent chance of lasting through the entire winter and an 80 percent chance of carryingΒ into the spring.
If the 2015 El NiΓ±o proves to be long lasting, the major weather shifts could bring global changes. TheΒ western Gulf Coast of the US will probably see record rainfall. This could mean a lot of extra rain for the southernΒ California region which is typically impacted by droughts.
El NiΓ±o may change storm activity, causing strongerΒ hurricanes in the Pacific and quieter hurricanes in the Atlantic. The strongest effects are experienced in the winterΒ season. Countries in the Southern Hemisphere, such as Brazil, have seen less rain. For the Great Lakes and OhioΒ Valley, winter may be drier than usual, meaning a milder winter season. The temperatures are forecasted to be 40Β percent aboveΒ normal the first three months of 2016. There is also a 40 percent chance there will be less thanΒ normal precipitation or snowfall during this time. If El NiΓ±o keeps getting stronger as it is expected to, 2016 couldΒ be one of the hottest years on record.
If one was looking for a white Christmas this year, unfortunately it wasΒ not likely. The latestΒ forecast from the Climate Center are showed Ohio had a 90 percent chance of seeing temperatures aboveΒ normal on Christmas Day.
