| Abstract | Foram discutidos os padrões de evolução de temperatura, de umidade e de vento da camada limite atmosférica (CLA) no Oeste da Amazônia (Rondônia), durante a estação seca de 1994, sobre dois sítios de coberturas vegetais distintas: floresta nativa e pastagem. A distância entre os dois sítios é aproximadamente 80km, localizados na região de Ji-Paraná, próximos a 10oS e 62oW. Sobre a pastagem, durante o dia, a Camada Limite Convectiva (CLC) foi cerca de 80% mais espessa, com 2K a mais e 6g.kg-1 a menos, em média. A Camada Limite Noturna (CLN) sobre a pastagem também foi mais quente e mais seca e a quebra de sua estabilidade noturna ocorreu mais cedo e com maior freqüência no período matinal quando comparada com a da floresta. Em geral, os padrões de evolução nos dois cenários foram diferentes, porém existiram ocasiões em que as duas CLC comportaram-se de modo similar. Os resultados sugeriram, também, que fenômenos de média e grande escalas desempenharam papel importante no comportamento da CLA da região. ABSTRACT Some Aspects The Atmospheric Boundary Layer over Western Amazonia: Dry Season 1994 The evolution of temperature, humidity and wind patterns in the atmospheric boundary layer (ABL) was discussed for two types of vegetation cover, pristine forest and pasture, during the 1994 dry season. The two sites are about 80km apart and located in Rondonia State, Western Brazilian Amazonia, circa 10°S and 62°W. During the day, over the modified environment (pasture), the convective boundary layer (CBL) was 80% thicker, 2K warmer and 6g.kg-1 drier than the forest CBL. The nocturnal boundary layer (NBL) was warmer and drier, the breaking of its stability was more frequent and occurred earlier than the forest NBL in the morning hours. In general, the evolution of the patterns over the two sites were quite different but there were occasions when their boundary layers behaved similarly. The results indicated that the large and meso scales dynamic mechanisms had a significant influence on the behavior of the ABL over those tropical sites. |
