It can be seen as an area of above-normal ocean temperatures across the equatorial Pacific Ocean. You can see the El Nino in NOAA’s latest ocean anomaly analysis below. ![]() This feedback system spreads the ENSO influence globally, especially the Winter temperature and snowfall patterns. This way, it significantly alters the atmosphere-ocean feedback system. ![]() These changes affect weather circulation over the rest of the world with some delay.Īs you can see in the image above, a warm ENSO phase creates lower pressure than normal over the central and eastern Pacific Ocean and higher pressure in the west. We can observe large-scale pressure changes in the tropics with each new developing phase. We are currently in a strengthening El Nino phase, which will be at peak strength during the Winter season.ĮNSO significantly influences tropical rainfall, pressure patterns, and the complex ocean and atmosphere exchange. The cold phase is called La Nina, and the warm phase is called El Nino. Typically, there is a phase change around every 1-3 years. The main focus will be on the global long-range weather forecasting systems, where you will see the latest snowfall predictions for the upcoming Winter 2023/2024 and its month-by-month breakdown.ĮNSO is short for “El Nino Southern Oscillation.” This region of the equatorial Pacific Ocean changes between warm and cold phases. What does the latest ocean analysis data show, and what are the expectations for its development? ![]() From the United States to Canada and across the Atlantic to Europe, we will look at the latest snowfall forecasts and trends for the whole Winter, as February data is now also available.īut first, we will take a fast look at the leading global weather driver for the upcoming Winter, the ENSO anomaly in the Pacific Ocean. Winter 2023/2024 snowfall predictions show a global weather signal from El Nino, currently still getting stronger and ready for Winter.
