Regional circulations
vLatitude, altitude and continentality are the primary factors, but exposure to regional winds and ocean currents is also a factor vSome regional winds are associated with the latitudinal bands of high and low pressure (e.g., Pacific High, Aleutian low, Bermuda-Azores high) vOcean currents also play an important role.  Ex: Gulf Stream in Atlantic and Japanese Current in Pacific affect North America.
