Episode of Low Level Jets in the north and northeast coast of state of Para: a case study of 2002 april 21st to 22nd. Revista Brasileira de Meteorologia, online, v. 23, n. 3, p. 334-340, set. 2008.

Acesso em:.0102-7786http://www.repositorio.ufpa.br/jspui/handle/2011/2180In this study the characteristics of the vertical structure of an episode of Low Level Jets (LLJ) occurring in the coast of Para is described. Radiosonde data of Ajuruteua city in Bragança collected during the DESMATA Experiment (Impact of the Deforestation the Atlantic Coast of the Amazonian), taking place in 2002, from April 08th to 22th, are used. Among the detected cases during the rainy period, one specific case with 12 hours duration, average velocity of 15m/s and directed from NE to E in the point of maximum velocity was selected. The observational results have indicated that this LLJ located in the coast of Para was due to the combined action of two factors: (1) inertial oscillation and (2) superficial baroclinicity. These two combined factors sustained this LLJ with velocities between 10 and 13m/s during the day and between 14 and 16m/s during the night, at an average altitude of 800m above surface.engAcesso AbertoAmazônia brasileiraLitoralBragança - PAPará - EstadoAmazônia brasileiraMeteorologiaTurbulência atmosféricaJatos de baixos níveisContraste térmicoArtigo de Periódico10.1590/S0102-77862008000300008
