Document Summary
Daily radiation patterns: surplus of radiation that the surface is absorbing, coldest time of the day is the morning, warmest time of the day is 2 or 3pm. Energy travelling through air to space: conduction. Molecule to molecule transfer: convection/ advection. Energy transferred by movement of air parcels. Global sensible heat (h: heat you can feel, north atlantic/pacific ocean gives off sensible heat to the atmosphere, energy is moving from the atmosphere to the south atlantic and indian. Ocean: direction off sensible heat can differ. Global latent heat (le: deserts have very little latent heat because there is no water, northern canada (polar deserts) has very little latent heat transfer because water is in solid form, need water for latent heat transfer. September 20th, 2017: energy imbalance around the global. The urban environments: urbanizing cities modifies the energy, modifies the circulations from tall buildings (massive change, can create their own circulation patterns, urban heat island.
