ilmastojen

Ilmastojen is the genitive plural form of ilmasto, the Finnish noun meaning climate. As a grammatical inflection, it denotes possession or relation to multiple climates and is used when talking about the climates of several places or in phrases that describe climate in a broader or comparative sense. It is not a standalone concept but a case form that appears in climate-related discourse.

Common uses include phrases such as maan ilmastojen muutos (changes in the country’s climates), maailman ilmastojen vaihtelu (variation of the world’s climates), or alueellisten ilmastojen eroavaisuudet (differences between regional climates). In scientific and policy contexts, ilmastojen appears whenever the discussion involves more than one climate or when attributing characteristics to multiple climates rather than to a single climate.

Relation to related terms: ilmasto is the base noun meaning climate, and ilmastonmuutos is the standard Finnish term for climate change. The nominative plural for the base noun is ilmastot, while the genitive plural form ilmastojen is used to express “of the climates.” The use of ilmastojen is a routine linguistic tool in Finnish when detailing comparative climate information across regions, countries, or the globe.
