The atmospheric fields are three-dimensional fields by nature, the variation in longitude, latitude and altitude of winds, temperatures and the other quantities are normal. A major jump forward in the development of climate science was reached when it was realized that the analysis of simultaneous values of the variables contained significant information. Indeed, to advance scientific understanding it is essential to have a view of the relation that links together various climate variables, for instance the temperature and the pressure in various places.
