…it’s clear big El Niños need deviant trade winds to maintain feedback loop. During especially strong El Niños, like this year’s, trade winds sometimes reverse direction—and this week’s off-the-charts wind surge is at record-strength for so early in an El Niño event. Since all this takes place in the tropical Pacific Ocean—the planet’s biggest bathtub— fully mature El Niño has power to shift rainfall odds worldwide and boost global temperatures. That’s exactly what’s happening this year…defined by expanding, deepening pool of warmer-than-normal ocean water in tropical Pacific — has steadily grown stronger since the spring…presence of strong El Niño almost ensures that 2015 will become the warmest on record for Earth and will have ripple effects on weather patterns all over the world.
