La Nina usually forms during strong trade winds, which can tell us much about the state of global circulation. This is the currently active La Nina, still strengthening at the moment. Cold ocean anomalies extend across most of the tropical Pacific. This feedback system spreads the ENSO influence globally, especially the Winter temperature and snowfall patterns.īelow we have the latest surface analysis of the tropical Pacific Ocean. The image below shows the circulation pattern of a cold phase, which we are currently in.īy doing this, the ENSO significantly impacts tropical rainfall and pressure patterns, altering the atmosphere-ocean feedback system. We are currently in a La Nina phase, entering its 3rd year, which is a rare occurrence.ĮNSO phases significantly influence tropical rainfall, pressure patterns, and the complex exchange between the ocean and the atmosphere. 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.

Then, looking at the global long-range weather forecasting systems and historical data analysis, you will see the snowfall predictions for the upcoming Winter and how they are altered by these large-scale influences.ĮNSO is a region of the equatorial Pacific Ocean that changes between warm and cold phases. What does the latest ocean analysis data show, and what can we expect based on its past influence? From Canada to the United States and across the Atlantic to Europe, we will look at the new Full snowfall forecasts and trends, with February data now also available.įirst, we will look at the one main global weather driver in the upcoming weather seasons, La Nina. Winter 2022/2023 snowfall predictions show a global weather signal from the La Nina, now starting to cool down further, getting ready for Winter.
