As it moves south, water temperatures rise and atmospheric weather conditions are affected globally. The formal name of the process is El Nino-Southern Oscillation. The warmer air travels via the subtropical jet stream through North America and across the state. Mississippi also is affected by the subpolar jet stream, which can be carried south by El Nino and bring freezing temperatures. El Nino does more harm than good.
Agriculture usually suffers.
Little else is known about the weather pattern. Because El Nino is essentially an unpredictable weather phenomenon, it's hard to prepare in advance. Still, there's some good news in all of this. For questions or information about this page, contact Kay Fike Jones .
