How is the weather determined?

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area’s elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and …
