Document Summary
Weather: state of atmosphere at given time and place instantaneous weather = f(temperature, air pressure, humidity, cloud cover, wind speed and direction) Weather is instantaneous state of atmosphere at one point geographically at a specific time, weather is not climate. Climate: is the average weather over a long-term accumulation of about 30 years. Climate system: complex system that tries to understand interaction from all sub components, doing that keeping space and time in mind. All interactions between the atmosphere, hydrosphere, cyrospshere, lithosphere, and biosphere. System: group of interacting parts that form a complex whole. Components of a climate system: everything affect everything else, sea change feedback than measure reaction and see a difference. The forcing shown above represents the input that we are changing e. g. change in earth"s orbit may change the amount of heat that hits the earth. Numerous time scales, difficult to describe a ten year cycle from a thousand year cycle.
