摘要: Abstract Twenty years of radiosonde data have been analyzed in an attempt to develop a latitudinal structure climatology winds, temperature and geopotential at 30 50 mb the equatorial stratosphere. The fine resolution provided by WMO station network reveals several interesting features annual quasi-biennial cycles which dominate this region. For example, westerly easterly acceleration phases oscillation are markedly different. Westerly accelerations appear first equator, spreading outward with time higher latitude more intense, on average, than accelerations. uniform latitude, but leer time, sometimes occurring two stages. wind oscillations symmetric about while harmonic zonal is antisymmetric not proportional Coriolis paramete...
