Most calculations and diagnosis is based on a combination of both the 3 and 4 areas, which is why the main region is marked as 3.4.Д®ach ENSO phase has a different influence on the tropical weather and circulation and thus impacting the weather worldwide differently. The main regions are 3 and 4 and cover a large part of the tropical Pacific. We usually observe a global scale shift in pressure patterns during the emergence of the ENSO phases, each having a unique impact on the weather globally.Д«elow we have an image that shows all the ENSO regions. Air is descending in the eastern Pacific, creating stable and dry weather conditions, while rising air in the western Pacific causes frequent thunderstorms and a lot of rainfall.Д®NSO has a major impact on the tropical convection patterns and thus on the ocean-atmosphere system, through which its influence is distributed globally. The image below from NOAA Climate shows the typical circulation during a negative ENSO event. The tropical trade winds (the easterly winds that circle the Earth near the equator) usually initiate or stop a certain phase, as they mix the ocean surface and alter the ocean currents. This is a region of ocean in the tropical Pacific, which alternates between cold and warm phases. To keep it simple, ENSO is short for вЂњEl NiГ±o Southern OscillationвЂќ. The actual ocean-atmosphere system is called ENSO. This La Nina is actually just a different name for cold ocean temperatures in the tropical Pacific ocean. The development of a cold La Nina phase is the key feature in weather development for at least the next 6 months. But we will see if we can find anything similar in the early forecasts for Winter 2021/2022. This is what winter вЂњfansвЂќ in Europe and the United States hope for every winter. A blocking ridge over Greenland and North Pacific, with low pressure and colder air for the United States and Europe.

We will look at what this La Nina is and how it can/will influence the Winter weather season of 2021/2022.Д«elow we have an example of a pressure pattern for a вЂњperfectвЂќ winter scenario for both the United States and Europe. Global weather is a very complex system, with many large-scale and small-scale climate drivers. To try and understand the Winter season and its forecast, we must realize that there is no вЂњmagic bulletвЂќ when it comes to weather. The Winter forecast from major weather models captures this jet stream altering by the La Nina and shows its possible weather outcomes. It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world.

We recognize that technology system changes may inconvenience some users for a limited time, but ASME staff will continue to look for enhancements to our technology ecosystem and provide you with guidance on how to better use social media platforms and other ways to communicate and collaborate.The Winter season 2021/2022 will be under the influence of a new La Nina phase, emerging in the tropical Pacific ocean. Sections and Student Sections will be using the new portal which will provide resources and information to their constituents. You'll be notified directly with more details if your group is affected.

Some large public groups that used the ASME Community as their primary outward communication tool will be moved to. In addition, the system does not meet todayвЂ™s benchmarks for functionality or information security and is no longer supported by its original developers. Platform use has decreased by over 70% from its peak years. Therefore, on March 28, 2022, ASME will be sunsetting our eight-year-old ASME Community platform. ASME staff is evaluating and evolving our technology platforms to safeguard our constituents' security and move towards more modern technology to facilitate effective collaboration. ASME values the contributions of our members and volunteers to our codes and standards, events, programs, and publications, and takes your information security seriously.
