Dynamical Studies of the Atmospheric Pressure Variation

[摘要] This paper is an abstract of the same author's “Studies on Atmospheric Pressure Variation”(unpublished). The motion of individual air particle is obtained for a stationary concentric cyclone, and then the development of divergence, convergence and vertical current is discussed from the Lagrangian point of view. The mechanism of the atmospheric pressure variation is discussed in terms of the accumulation of vorticity, convergence at low level divergence at upper level, vertical stability, horizontal density advection by adiabatic process, and the trajectories of each air particle. The reader who wishes a more complete and datailed treatment must be referred to the original paper (to be published in the Memoirs of the Central Meteorological Observatory).
