Some Problems of the Dynamics of the Polar Middle Atmosphere and Requirements for Further Observations (g. Future Plan) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions : Part II)

Abstract

A brief discussion is made on the structure and dynamics of the polar middle atmosphere. It is pointed out that the difference between the northern and southern hemispheres is largest in winter in the polar region for both the mean structure and planetary waves. 0n the basis of this consideration, an emohasis is placed on the need of making the well-coordinated observation program in Antarctica during the MAP period.
