Description:An analysis model, based on Sasaki's variational technique, has been utilized to describe the fields of atmospheric motion, temperature and specific humidity over Lake Ontario at two times during the invasion of the lake by an Arctic air mass. The two times chosen were: (1) when the leading edge of the cold air mass was encroaching upon the lake and (2) fifteen hours later, when the air mass completely fills the lake basin. Special surface and upper-air data collected in conjunction with the International Field Year for the Great Lakes are interpolated to eleven a surfaces extending from the earth's surface to 500 mb. The weak constraint variational formulation is used with variable weights assigned to the interpolated data.
