![]() ![]() They can mix the ocean surface layers and change the ocean surface currents and temperature. The tropical trade winds are a vital connection between the oceans and the weather. The key here is the word “two-way.” For example, we sometimes look at the ocean anomalies and how they will influence our long-term weather, while the weather also influences the ocean anomalies. It is rather complex, but you can see a two-way system with many small and large-scale factors. In the image below, you can see the air-sea interaction. Oceans cover over 70% of the planet’s surface and play a significant role in the Earth’s climate system. But we will see if we can find any similar trends in the first Winter 2022/2023 forecast. This is what every winter fan in Europe and the United States hopes for every winter. A blocking high pressure over Greenland and North Pacific, with low pressure and colder air from the United States into Europe. ![]() We will first examine what this La Nina really is and how it will influence the Winter season of 2022/2023.īelow we have a pressure pattern of a La Nina winter in 10/11. Global weather is a very complex system, with many large-scale and small-scale climate influencers. To try and understand the Winter season, we must realize that there are many “drivers” of weather. But there is a new ocean anomaly emerging that will also play its part. It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world. A first look at Winter 2022/2023 forecast shows an obvious influence of the third-year La Nina phase. ![]()
