MeteoSwiss uses AI to improve thunderstorm forecasts
MeteoSwiss put a new deep-learning model into operation in summer 2026 after four years of development. The system ingests radar and lightning data every five minutes across Switzerland and computes probabilistic thunderstorm hazard forecasts for the next hour. Training took place on supercomputers in Lugano. According to the federal office, the AI model increases warning lead time and reduces false alarms; forecasts will feed the MeteoSwiss app and federal website and support severe-weather warnings, aviation safety and civil protection. Meteorologists will continue to make final assessments in complex situations. The story was published on 2026-08-27.
Applied AI deployment in national meteorology demonstrates technical progress but has limited direct impact on the AdTech/MarTech industry.

Key Takeaways & Evidence Grounding
- MeteoSwiss deployed a new deep-learning model into operational use in summer 2026 after four years of development.
- The model analyzes radar and lightning data for the whole of Switzerland every five minutes and calculates the probability of thunderstorm hazards for the coming hour.
- Model training was performed on supercomputers in Lugano using large datasets of radar, lightning and satellite data.
- MeteoSwiss says the AI system improves warning lead time and reduces the false-alarm rate; forecasts will be used in the MeteoSwiss app and the federal office's website for warnings, aviation safety and civil protection.

Swiss AI 'Apertus' Adds Image and Audio Analysis
Apertus, a Swiss AI model developed by academic institutions, can now analyze images and sounds, according to the Swiss newspaper Le Temps. Researchers caution that Apertus remains a model rather than a finished public product and using it as a search engine is still risky, said Imanol Schlag of ETH Zurich's Centre for Artificial Intelligence. The project is backed by ETH Zurich, the École polytechnique fédérale de Lausanne (EPFL) and the national supercomputing centre CSCS in Lugano. Its stated aim is to provide a fully transparent alternative to commercial AI products that companies, authorities and researchers can reliably build on. The story was published on 2026-07-27.
SRG Archive to Train Swiss AI Models
Switzerland's SRG archive is planned to be made available to Swiss higher-education institutions in Zurich and Lausanne to help train a national AI language model. Susanne Wille, identified as Generaldirektorin, supports providing the holdings to the universities. Developers of the Apertus language model say the SRG audio material would let the model process all national languages and dialects and add journalistically verified knowledge about Switzerland. HSG professor Damian Borth called the cooperation "clever," noting the data would remain under Swiss sovereignty. Legal questions are still open; implemention could be possible within months according to developer Imanol Schlag.
AI Superforecasters Near Human Parity
The article examines the rapid rise of AI "superforecasters": specially scaffolded LLMs that research and produce probabilistic forecasts. Startups such as FutureSearch and Preseen claim strong returns on prediction markets and finance (e.g., FutureSearch produced a 7% forecast that US respiratory infections will halve by 2040; Preseen gave 8.8%). Metaculus benchmarking shows brand-name base models approaching crowd predictions as of May 2026, while forecasting-focused scaffolds add roughly nine months of effective model progress; scaffolded AIs are approaching top professional human forecasters and may reach parity within months. The piece discusses implications for finance, prediction markets, policy advice, and public trust, and argues that readily-available AI forecasters could democratize access to high-quality forecasting while reshaping markets where forecasting labor is valuable.
