The invention also discloses a device for regulating climate, i.e. an automatic air tower. The automatic air tower comprises a column (1) with an air inlet (12) at the bottom, wherein the column comprises a startup unit (13) and a shutdown unit (14) inside and has an air outlet (15) at the top. Air temperature inside the column is controlled higher than that outside. Air flows into the air flow pathway in the column through the air inlet and then out through the air outlet, generating an initial bottom-to-top air flow in the pathway. The aforesaid method and tower can prevent and eliminate the formation of haze and cool the earth's ground.
