Microclimate
Local set of atmospheric conditions that differ significantly from the surrounding area
A microclimate (or micro-climate) refers to localized atmospheric conditions in the near-surface layer, which includes the air immediately above a surface as well as the shallow soil and water environments below it. A microclimate can range in size from a few meters to at most a few kilometers across. It is characterized by a set of persistent, measurable differences in the climate conditions from those in the adjacent surrounding areas.
