Course for graduate students 1.1 Definition Climate Climate in a narrow sense is usually defined as the average weather,or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands of years. The classical period is 3 decades, as defined by the world Meteorological Organization(WMO). These quantities are most often surface variables such as temperature precipitation, and wind. Climate in a wider sense is the state including a statistical description, of the climate system. 2021/2/22 Assessment of climate/ch 14of42
