Abstract : Within the period from January 18 to February 10, 1958, a stratospheric warming occurred in the Northern Hemisphere. Maps of height and temperature for 100, 50 and 25 mb illustrate the onset of the warming in the region of the warm belt and the subsequent migration of the warm center across western Europe, Iceland and Canada. Vertical motion at 100, 50 and 25 mb was computed by the adiabatic method. Horizontal divergence at 100, 75 and 50 mb was computed. Vorticity and the vorticity budget at 100, 50 and 25 mb were evaluated. A numerical experiment was performed in which 25-mb temperatures were computed using data primarily at 100 and 50 mb. The computed values were found to be better than those obtained by a straightforward extrapolation scheme, particularly near the height of the warming.
