The flow or motion of a fluid. A quantitative description of climate showing the characteristic values of climate variables over a region.
Climate refers to the statistical collection of weather conditions over a specified period of time.
More specifically, it refers to motion associated with a rising current of air. In the context of climate modeling this usually refers to a numerical model which simulates both atmospheric and oceanic motions and temperatures and which takes into account the effects of each component on the other. An average that is done according to a specific criteria. For example, one could composite the rainfall at a station for all years where the temperature was much above average. Often used in reference to the axis of maximum mid-latitude westerlies located in the high troposphere.
