| Resumo | Although Amazonia is still mainly covered by tropical forest it is suffering from a high rate of deforestation. This impact on climate is likely to depend strongly on the scale of deforestation. As a part of 2002 LBA/DRY-TO-WET experiment the coupling between a typical Amazonian ranchland and the CBL has been investigated using radiosoundings (sondes RS80-15G from Vaisala Oy) at 8, 11, 14 and 17 Local Time. The field campaign held from the end of the dry season (Sept 15-30) to the onset of the wet period (Oct, 15-30). Profiles of potential temperature and specific humidity have been used to compute the mean properties of the CBL, as well as the height of the CBL. The CBL height varied from a typical value around 1800-2200 m during the peak of the dry season to a figure around 1200-1400 m in the wet period due to local showers. The average height for the dry period (Phase I) was 1700 m and for the wet season (Phase II) was 1320 m. The potential temperature and humidity profiles did not changed remarkable from the Phase I to II oscillating from 306 307 K (reducing 0,4 K on average) and 12 14 g/kg (increasing 0,7 g/kg on average). During the onset of the wet season, some local convective showers have occurred and produced a remarkable change in the structure of the CBL. Some interesting and special events have been analyzed regarding destruction of the CBL due to the rainfall and coupling between nocturnal jet and development a shallow CBL during the nighttime. The influence of the rainfall destroying the CBL was investigating on Oct 19, 2002: the height of the CBL was around 1400 m at 11 LT with an average potential temperature (q) around 304 K and specific humidity (q) of 13,5 g/kg. After an intensive (15 mm at 13 LT and before the 14 LT sounding) and short (less than l hr) rainfall, the CBL has been destroyed (height around 700 m) with q of 298 K close to the surface and showing a stable structure and specific humidity around 15-16 g/kg. There was a remarkable reduction of the air temperature (around 10 C), solar radiation (from 600 W/m2 to 50 W/m2) and sensible heat flux (from 120 W/m2 to a negative value 10W/m2) and increase of relative humidity (around 40%). After the rain, there was a solar heating but this energy was not enough to erode the stable layer and develop a new shallow CBL. The case of the nocturnal jet had occurred during the night from Sept 23-24 associated with strong wind of 11 m/s at 500 m. This strong windshear created an unexpected shallow mixed layer (height of 400 m) during the night instead of the nocturnal/stable typical pattern. The usual stable layer was mainly produced by the surface cooling while this shallow CBL was due to mechanical turbulence associated with the nocturnal jet. | |||
