STRATOSPHERIC WIND OBSERVATIONS BETWEEN 20 DEGREES NORTH AND 20 DEGREES SOUTH OF THE EQUATOR DECEMBER 1959 TO JUNE 1962,
Abstract
Stratospheric wind data observed between November 1959 and the early months of 1962, in a forty degree latitude band from 20 degrees north to 20 degrees south of the equator, were reviewed and analysed. Stratospheric behavoir at balloon flight altitudes, at and above 28 km. was the principal concern of the investigation. A series of studies of wind direction and speed shows that no diurnal variation occurs consistently enough to be forecastable; wind speed varies little with height within the levels examined (28 to 34 km.); easterlies and westerlies are strongest at midseason, weakest at onset; peak speeds of westerlies correspond with those of easterlies at onset; transitions from one wind regime to the other propagate downward through the stratosphere at speeds that increase considerably away from the equator.
