mesoclimate, a term of climatic scale, intermediate between regional climate or macroclimate, and the very small scale microclimate. It encompasses the more specific terms topoclimate and site climate, and has largely replaced both in specialist usage (although the word microclimate is widely and incorrectly used by non-specialists for mesoclimate). The usual scale of a mesoclimate is in tens or hundreds of metres, so one speaks correctly of the mesoclimate of a particular vineyard or potential vineyard site.
