Chapter 3. Modelling the climate system
Introduction to climate dynamics and climate Modelling - Chapter 3. Modelling the climate system Introduction What is a climate model ? In general terms, a climate model could be defined as a mathematical representation of the climate system based on physical, biological and chemical principles (Fig. ). The equations derived from these laws are so complex that they must be solved numerically. As a consequence, climate models provide a solution which is discrete in space and time, meaning that the results obtained represent averages over regions, whose size depends on model resolution, and for specific times.
Figure 3.1: Schematic representation of the development and use of a climate model. 3.1.2 Types of models . Simplifications are unavoidable when designing a climate model as the processes that should be taken into account range from the scale of centimetres (for instance for atmospheric turbulence) to that of the Earth itself.
