The model captures key climate variability modes and aims to extend weather predictability beyond two weeks.", "body_md": "arXiv:2606.28546v1 Announce Type: new\nAbstract: Recent advances in AI-driven weather and climate modeling have improved forecast skill while reducing computational cost. However, existing data-driven approaches are limited in their ability to model coupled Earth system dynamics, which is required for extending predictability beyond the ~2-week horizon. To address this, we introduce NIVA, a multimodal foundation model designed to learn unified representations across Earth system components. While the full framework targets atmosphere, ocean, ice, and land interactions, we focus here on a two-modality setting (ocean and atmosphere) as a controlled proof of concept to evaluate whether foundation models can learn coupled dynamics. Trained on large-scale Earth system simulations, NIVA learns physically meaningful cross-modal structure, providing a foundation for subseasonal-to-seasonal prediction. As initial validation, we show that NIVA captures key modes of climate variability through accurate prediction of major climate indices.", "url": "https://wpnews.pro/news/niva-a-multimodal-foundation-model-for-actionable-earth-system-intelligence", "canonical_source": "https://arxiv.org/abs/2606.28546", "published_at": "2026-06-30 04:00:00+00:00", "updated_at": "2026-06-30 04:29:59.808274+00:00", "lang": "en", "topics": ["machine-learning", "large-language-models"], "entities": ["NIVA"], "alternates": {"html": "https://wpnews.pro/news/niva-a-multimodal-foundation-model-for-actionable-earth-system-intelligence", "markdown": "https://wpnews.pro/news/niva-a-multimodal-foundation-model-for-actionable-earth-system-intelligence.md", "text": "https://wpnews.pro/news/niva-a-multimodal-foundation-model-for-actionable-earth-system-intelligence.txt", "jsonld": "https://wpnews.pro/news/niva-a-multimodal-foundation-model-for-actionable-earth-system-intelligence.jsonld"}}
