0000002236 00000 n The movement of air across the planet occurs in a specific pattern. The weather we experience on the surface of the planet comes as a result of this global atmospheric circulation model. Characterizing weather requires that we measure conditions such as temperature, precipitation, air pressure, wind speed and direction, humidity. The UK has a temperate climate. Due to the Earth’s spin, each cell has prevailing winds associated with it. Fully developed superrotation—60 times faster than the planetary rotation (243 days)—is simulated using a Venus-like atmospheric general circulation model (AGCM).

Furthermore, predictability is limited by model errors due to the approximate simulation of atmospheric processes of the state-of-the-art numerical models. Work at GFDL over the past decade has improved our understanding of how circulation changes and changes in both precipitation and evaporation, particularly over land, are interrelated. Furthermore, predictability is limited by model errors due to the approximate simulation of atmospheric processes of the state-of-the-art numerical models. )/RD[22.4811 22.6589 22.4811 22.6589]/Type/Annot/AP<>/BE<>>> endobj 106 0 obj<>/ProcSet[/PDF/Text]>>/Type/XObject/BBox[144.49 688.316 443.229 773.742]/FormType 1>>stream 7.1: Scales of atmospheric motion.
