Item Acesso aberto (Open Access) Complexo Convectivo de Mesoescala observado em 27/11/2002 no nordeste da Argentina(2008-12) CAMPOS, Claudia Rejane Jacondino; LIMA, Edna Cristina Sodré; PINTO, Luciana BarrosIn this work were analyzed the synoptic situations associated to a Mesoscale Convective Complex (CCM), observed on 11/27/2002 in the northeast of Argentina. Infrared imagery from GOES-8 and simulations from BRAMS regional model were used. The model simulation, with three hours issues, allowed detailing the behavior of the meteorological variables in large scale that affect the MCC life cycle, being able to reproduce the suitable conditions to its beginning, development and dissipation. The results showed that the MCC studied presented similar characteristics to those observed by several authors.Item Acesso aberto (Open Access) Episode of Low Level Jets in the north and northeast coast of state of Para: a case study of 2002 april 21st to 22nd(2008-09) SOUSA, Adriano Marlisom Leão de; CAMPOS, Claudia Rejane Jacondino; ROCHA, Edson José Paulino daIn 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.
