My impression is that it is the area of the cloud free subtropical high pressure cells of descending air that is a strong variable factor explaining the change in the temperature of the in - feed waters that become the westerly currents that occupy the tropical latitudes. (wattsupwiththat.com)
14) The polar high pressure cells expand and intensify producing increasingly negative Arctic and Antarctic Oscillations. (newclimatemodel.com)
They are what create individual weather systems, like high pressure cells and storms,» Rutgers University climate researcher Jennifer Francis, who reviewed the new study, said in an email. (climatecentral.org)
