- Jean-Baptiste Lamarck pioneered cloud classification in 1777, dividing clouds into five types using French terms to make meteorology accessible to non-scholars, unlike Luke Howard's later Latin-based system.
- Lamarck published meteorological yearbooks from 1799, forecasting weather based on lunar gravitational effects ('atmospheric tides') and encouraging public participation by inviting readers to annotate and return their copies.
- He viewed science as intimate and participatory, emphasizing the observer's sensory and emotional engagement with weather phenomena like storms, which he described lyrically as beautiful spectacles.
- Lamarck's work faced opposition from colleagues like Pierre-Simon Laplace, who dismissed his probabilistic forecasts as unscientific astrology, reflecting a deeper conflict between deterministic and non-deterministic worldviews.
- In 1800, Lamarck helped establish the world's first national weather bureau under Minister Jean-Antoine Chaptal, but it was short-lived, dismantled after Chaptal's resignation and replaced under Laplace's influence.
- Napoleon eventually banned Lamarck's meteorological publications in 1809, seeing his materialist, participatory science as politically subversive, despite Lamarck's focus on nature studies.
- Lamarck's legacy influenced later meteorologists, like Charles Martins in 1848, who revived his participatory approach and contributed to the founding of Météo-France.
