Each prediction takes less than a minute on a single TPU; it would take hours on a supercomputer using physics-based models.<\/p>\n<p data-block-key=\"gehb\">Our model is also highly skillful and capable of higher-resolution predictions, down to the hour. Overall, WeatherNext 2 surpasses our previous state-of-the-art WeatherNext model on 99.9% of variables (e.g. temperature, wind, humidity) and lead times (0-15 days), enabling more useful and accurate forecasts.<\/p>\n<p data-block-key=\"dsjdl\">This improved performance is enabled by a new AI modelling approach called a <a href=\"https:\/\/arxiv.org\/abs\/2506.10772\" rel=\"nofollow noopener\" target=\"_blank\">Functional Generative Network<\/a> (FGN), which injects \u2018noise\u2019 directly into the model architecture so the forecasts it generates remain physically realistic and interconnected.<\/p>\n<p data-block-key=\"56vt3\">This approach is particularly useful for predicting what meteorologists refer to as \u201cmarginals\u201d and \u201cjoints.\u201d Marginals are individual, standalone weather elements: the precise temperature at a specific location, the wind speed at a certain altitude or the humidity. What&#8217;s novel about our approach is that the model is only trained on these marginals. Yet, from that training, it learns to skillfully forecast &#8216;joints&#8217; \u2014 large, complex, interconnected systems that depend on how all those individual pieces fit together. This &#8216;joint&#8217; forecasting is required for our most useful predictions, such as identifying entire regions affected by high heat, or expected power output across a wind farm.<\/p>\n","protected":false},"excerpt":{"rendered":"Weather predictions need to capture the full range of possibilities \u2014 including worst case scenarios, which are the&hellip;\n","protected":false},"author":2,"featured_media":268976,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[554,733,4308,3085,86,56,54,55],"class_list":{"0":"post-268975","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-artificial-intelligence","8":"tag-ai","9":"tag-artificial-intelligence","10":"tag-artificialintelligence","11":"tag-none","12":"tag-technology","13":"tag-uk","14":"tag-united-kingdom","15":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/268975","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=268975"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/268975\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/268976"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=268975"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=268975"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=268975"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
