Document Summary
January 6, 2020: everything can be derived from the 3 laws of conservation, conservation of energy, conservation of mass, conservation of momentum. 1. 1 definitions: climatology: study of global climate system. A and b are part of a system if a influences b and b influences a: climate system: includes, atmosphere, oceans, lithosphere. Ice sheet: temperature, wind, pressure, precipitation, cloud cover agriculture. Each of these components interacts with and influences all the other components. Compared to geothermal heat flux (heat from earth"s core) of 0. 3w/m2 averaged over earth. Geothermal heat is not part of the system because not influenced by other components. Is external to system, even though physically within one of the: climate: mean state of the climate system plus variability and higher order statistics system"s components (lithosphere) Need to consider average as well as magnitude of fluctuation: annual variation in precipitation can be just as important as mean for. Change in climate occurs if mean, variability, or both change.
