Current Models At present, computer models do exist for the four regions where space weather originates, and interacts with Earth (Sun, solar wind, magnetosphere, upper atmosphere), but the models do not yet include all the physical processes involved. Nor are the models integrated: able to interact with each other as the phenomena actually do in space. The models are based on the physical principles that underlie the processes common to a specific region – and consequently, in their present state of development, they are limited to simulating only that region. CISM’s first effort will be to integrate, for the first time, existing simulations of the four regions of space weather activity. A model having such complexity, requires a massive computer capability. STAY TUNED!!!
