El nino and la nina difference

Forecasters are warning that the probability is growing for an El Niño event to develop in coming months, which could cause significant changes in weather around the world, including in the United States. In recent years, a long-lasting La Niña event has caused natural disasters and massive weather impacts around the world, with record-setting cyclone seasons in the Atlantic Ocean and heavy rains in the Southern Hemisphere. Now, it appears that the opposite weather pattern could potentially take hold, with a growing probability that an El Niño event will start, So what exactly is the difference between El Niño and La Niña? Here’s what you need to know. Feeling out of the loop? We'll catch you up on the Chicago news you need to know. Sign up for the weekly What is El Niño? In an El Niño event, trade winds tend to weaken, which pushes warmer-than-normal water back into the central and east-central Pacific Ocean, The event also can cause excessive precipitation and warmer-than-normal temperatures in different areas depending on the placement of the dominant jet stream. 3 hours ago Scientists do note that the severity of El Niño can vary greatly, and that some events can showcase different environmental and climate impacts. What Are Its Impacts on the Midwest? Illinois and the Chicago area typically see warmer temperatures as a result of El Niño, especially in the fall and winter months, according to The entire Midwest also typically sees below-normal levels of precipitation i...

We often hear the terms El Niño and La Niña thrown around in climate-related conversations, but what exactly do they refer to? This article will give a review of the cycle known as the El Niño Southern Oscillation. — Scientists have been crunching huge amounts of data with state-of-the-art machine learning algorithms to model the long-term fluctuations of the climate. However, well-understood, medium-term variations like El Niño and La Niña could help us predict imminent changes with higher precision. The Difference Between El Niño And La Niña First, El Niño means “the little boy” in Spanish, and La Niña, “the little girl”. They are opposite phases of the El Niño Southern Oscillation (ENSO), a temperature variation between the ocean and the atmosphere over the east-central Tropical Pacific. These phases usually occur once every few years and last 9 to 12 months, but can sometimes last years. Their frequency is quite irregular, and El Niño events happen more frequently than their counterpart. JOIN THE MOVEMENT TODAY The system can be broken down into three parts. The Neutral Phase When neither El Niño or La Niña are in action, low altitude trade winds blow east to west, from the American continent toward Oceania. These winds fly low and carry warm, moist air toward the western Pacific, thus warming its sea surface temperature (SST) and keeping the eastern waters cool. Neutral phase of the ENSO cycle.

- [Instructor] Every few years you might hear about El Nino in the news. And this also might come with powerful images of flooding and rainfall, but it is not just a storm. It's actually a climate pattern that takes place in the Pacific Ocean. And we'll get a little bit more into what that actually means. Now, fun fact about how El Nino is named is that a long time ago, South American fishermen noticed one December that the Pacific Ocean was actually warmer than it normally is. And this brought about an abundance of fish. So because they were grateful, they named this event El Nino to correlate with the commemoration of Christ in this part of the world during Christmas time. So that's a little trivia you can keep in your back pocket, but back to what we hear about El Nino in the news, you might also notice that it isn't talked about every single year and that's because El Nino comes around every two to seven years on average. And scientists are still not sure exactly what triggers El Nino, but they know what signs to look for once it is approaching or once we're in that event. So even though it's true that El Nino can bring about heavy rainfall and flooding, it can also cause severe drought. So it's really important to note that different regions around the world experience different effects of El Nino. And we'll see a few examples of those. So sometimes an El Nino year is actually, a little bit helpful and might bring about some much needed rain, but other times bigger an...
