THERMAL CONDITIONS IN THE ARCTIC STRATOSPHERE NEAR 8OW IN JANUARY

Abstract

Revised means, frequency distributions and other statistics based on ten years of January temperature observations at the 200-, 100- and 50-mb levels are presented for four arctic stations. The frequency distributions are shown to be markedly bimodal, a characteristic that becomes more pronounced with increasing height and latitude. Thermal conditions in the arctic and antarctic stratospheres are compared with the aid of recent IGY data.
