Answer:
La Nina, the direct opposite of El Nino.
Step-by-step explanation:
La Nina, the direct opposite of El Nino, occurs when sea surface temperatures in the central Pacific Ocean drop to lower-than-normal levels. The cooling of this area of water near the equator, which typically unfolds during late fall into early winter, yields impacts around the globe. La Nina puts more emphasis on the northern jet stream, weakening the southern jet stream. Winter in the Northeast is extremely variable during La Nina, ranging from colder and drier to mild and stormier.
