摘要

Irregularidades com escala de metros s?o estudadas rotineiramente com radares nas regi?es de baixas latitudes e equatoriais. Em ambos os estudos é comum a ocorrência de ecos da regi?o E (90 a 120 km de altitude). Os ecos resultantes s?o denominados de Tipo I e Tipo II de acordo com sua assinatura espectral. Neste trabalho nós mostramos que a velocidade de fase dos ecos tipo I aumenta à medida que diminui a altitude devido a efeitos térmicos causados pela própria irregularidade durante seu processo de desenvolvimento. Nós também mostramos que os ecos do Tipo II podem ser influenciados pelos ventos neutros atmosféricos ao ponto de revelar a presen?a de ondas do tipo Kelvin-Helmholtz, conforme demonstrado em alguns exemplos de estudos recentes realizados com o radar Gadanki na índia.
