Eleventh International Conference on Climate Change: Impacts & Responses

Abstract

Global warming has now reached the energetic phase of H2O’s return to the earth. This phase is the result of the accumulation of thermal energy exchanges in the Earth-Ocean-Atmosphere system that resulted in the thrust reversal of the energy balance toward the poles. This situation is characterized by a new thermal distribution: above the ocean, the situation is more in surplus, and the land - atmosphere is negative. Warm thermal advection easily reach the Pole, as well as cold advection push deep into North Africa. This “New Ground Energy Balance” establishes a “New Meridian Atmospheric Circulation (MAC)” with an undulating character throughout the year, including the winter characterized by intense latitudinal very active energy exchanges between the surplus areas and the deficit on the one hand, and the atmosphere, the ocean and the continent on the other. This situation increases the potential evaporation of the atmosphere and provides a new geographical distribution of Moisture: the excess water vapor is easily converted by cold advection to heavy rains that cause floods or snow storms. The new thermal distribution reorganizes the geography of atmospheric pressure: the ocean energy concentration is transmitted directly to the atmosphere, and the excess torque is pushed northward. The Azores anticyclone is strengthened and is a global lock by the Atlantic ridge at Greenland, which imposes on the jet stream a positive ripple, very strongly marked poleward, bringing cosmic cold advection of polar air masses winter over from Europe to North Africa. Hence the enormous meridian heat exchanges north-south-north.
