Abstract:

A general circulation model for climate, emphasizing physical phenomenology, is developed as part of an overall consideration whether it is feasible to control or advertently modify the earths surface climate at the middle and high northern latitudes. Ultimately, the answer to this feasibility question will be used to evaluate theoretically the current capabilities of world superpowers in their possible use of controlled climate modification for political or military purposes. The use of the model, along with the most recent reduction of experimental data for the long-term statistics of the current general circulation, allows the semi-experimental determination of certain statistics which are difficult to measure directly. These are the wave and amplitude parameters of the baroclinic disturbances, and the vertical transports, which the model determines as a function of latitude. A local test of the model proved successful for the latitude where the large-scale transport of angular momentum vanishes as the large-scale transport of sensible heat reaches a maximum, experimental and semi-experimental results show agreement.
