　　讲座内容介绍：

　　Radiant energy from the sun is unevenly absorbed in the Earth system because of the sun-Earth geometry. The energy is transformed into internal energy (temperature-related sensible heat), latent energy (associated with phase changes of water), potential energy (associated with height and gravity), and kinetic energy (associated with motion). The energy may be stored in atmospheric, ocean, cryosphere and land heat reservoirs and moved around mainly by the atmosphere and ocean, which give rise to our weather and climate. Ultimately it is radiated back to space as infrared radiation, and for a stable climate the global mean outgoing and incoming radiation must balance. This provides new commentaries on the variability in the Atlantic Meridional Overturning Circulation (AMOC) and El Niño-Southern Oscillation (ENSO).
