  • KTLA’s El Niño 2015-2016 Guide

    Introduction: El Niño is a phenomenon of the ocean-atmosphere system in the tropical Pacific. It displaces a huge volume of warm water from the western Pacific, moving it to the eastern Pacific. This disruption has important consequences for weather and climate around the globe. El Niño is not a single storm like Hurricane Katrina. Nor is it a single tornado or severe thunderstorm. We cannot say that a single storm is El Niño. Rather, we might see a series of […]

  • El Niño 2015-2016: Defining El Niño

    ENSO – El Niño Southern Oscillation El Niño is one of three cyclical phases of the Pacific Ocean. Generally the El Niño phase occurs every five to seven years. The neutral phase is defined by average sea surface temperatures and heights, along with typical weather patterns. La Niña is the positive or cold phase of the Pacific. When this occurs, sea surface temperatures, from near the South American coast westward into the equatorial Pacific, will drop below normal, while abnormally […]

    El Niño 2015-2016: El Niño and Southern California Weather

    Shifting the jet stream and enhancing storms are the mechanisms for bringing flooding rains to Southern California. Storms ride the jet stream, which steers them into North America. During our rainy season, the jet stream will normally rope its way down into the Pacific Northwest carrying storms from the Gulf of Alaska. Occasionally this current of air will move storms into California, with Southern California getting the tail end of these systems. The El Niño tends to cause the jet […]

    El Niño 2015-2016: Impacts From El Niño

    This year one of the most frequently asked questions to weather people is, “when does El Niño start?” The answer is it’s already here and it’s affecting the environment around the globe. Early in March, NOAA declared the onset of El Niño. At the same time 1,050 sea lion yearlings were being rescued mostly along the Southern California coast. Although the El Niño had only recently been called, the Pacific was already undergoing dramatic warming. According to NOAA fisheries, changes […]

    El Niño 2015-2016: What Can We Expect?

    Meteorologists have a great deal of trepidation about what we can expect from the effects of El Niño. Simply stated: there are no guarantees in predicting weather. The 2015 El Niño is already considered a strong El Niño. The history of strong El Niños demonstrates that the dice are loaded in favor of wetter-than-normal weather in California. Unfortunately that also means that we could roll a dud. That said, here are three weather scenarios for this coming winter in Southern […]

  • El Niño 2015-2016: Distinguishing Normal Weather From El Niño-Driven Storm Patterns

    The rainy season in Southern California extends from November until the end of April. The heaviest rains in Los Angeles occur in January, February, March and April. This will most likely be true during the current El Niño. We would normally see about 13 inches of precipitation during these months. With a strong El Niño we could see 35 inches of rain during the upcoming January, February, March and April. Rainfall amounts 150 percent to 200 percent of normal are […]
