Regional climate effects

Atlantic ocean current

urban area that is significantly warmer than its surrounding rural areas due to human activities

thumb|A small scale terrain depression which creates a frost hollow, due to localized atmospheric conditions. 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. These differences may be subtle or pronounced wh
