They are used for a variety of purposes from study of the dynamics of the climate system to projections of future climate. All climate models take account of incoming energy from the sun as short wave radiation, chiefly. Mathematical models can also be used to forecast future behavior. Example: An ice cream company keeps track of how many ice creams get sold on different days. By comparing this to the weather on each day they can make a mathematical model of sales versus weather.
