Predictability of the first kind : Predict the future based on initial conditions , with boundary conditions constant. This is limited by the chaotic nature of the atmosphere, which is a physical system with built-in instabilities, in vertical convection ( e.g. , thunderstorms) and horizontal motion ( e.g. , baroclinic instability - development of low pressure systems, such as hurricanes and Nor’easters). (Source: Prof. Alan Robock, Rutgers University) Consider a prediction using the above equation of the future state of the variable X
