GEO 110 Lecture Notes - Lecture 6: Earth System Science, Climate Model, Regression Analysis
Numerical modeling using general circulation models (gcm) Past climate past climate (paleoclimatology) proxy indicators ice-core data: sediments, coral reefs, ancient pollen tree-ring. Numerical prediction using gcms: general circulation models. General circulation models atmospheric gcm and ocean gcms. Coupled aogcm are also coupled with other modelled aspects of the climate system to form a. Simulate the evolution the earths climate system over time, including atmospheres, oceans. Research of the dynamics of the climate systems, forecasts(short term and long term), projections of the impacts of anthropogenic green house gases and aerosols on future climates. Prediction is a typically a climate forecast only a few season into the future (short term) Projection is a climate simulation in which a set of scenarios of possible gng and aerosols emission are incorporated. It projects the evolution of climate over the next century(long term) Simulation is the most general term describing al output of gcms.
