| Abstract | With the purpose of describing the roles of Lake Titicaca and Salar de Uyuni on the modulation of the mesoscale circulations and associated rainfall in the altiplano, hourly wind profiles and daily rainfall observations were collected during the rainy season of 2002-3, in parallel to the South American Low Level Jet Experiment (SALLJEX) field campaign. The wind data were collected in the vicinity the lake and the salar during two short (5-7 consecutive days) field experiments with networks of 5 to 7 pilot balloon stations distributed along the edges. The rainfall data were collected from November 2002 through May 2003 by a ~200-unit simple raingauge network in the vicinity of Lake Titicaca. GOES-8 IR4 satellite imagery and gridded analyses from the AVN Model were used to support the conclusions. The nocturnal convective storms that respond to the mesoscale circulations induced by Lake Titicaca proved to be the largest source of rainfall in the northern altiplano. During the December-February 2002-3 period the observed values were as high as 200 mm month-1 over the lake, almost doubling the 110 mm month-1 collected along a ~50km-wide strip that extended inland from the lakeshore. The breezes induced by both the lake and the salar were of comparable magnitude (3-5 m s-1 during the early afternoon and 1-5 m s-1 during the early morning) and depth (500-700 m AGL), with slightly stronger (+0.5-1.5 m s-1) and organized circulations over the salar in response to larger diurnal temperature contrasts in the drier and less complex surrounding terrain of the southern altiplano. Divergence calculations at 150 m AGL divergence showed divergent (convergent) flow during the afternoon (early morning) over both features. The periods of divergence were less prolonged and less intense over the lake than over the salar. This, together with the presence of upward surface moisture flux, high boundary layer moisture content, and low mid-tropospheric shear, allow for nocturnal convection to develop only over the lake.. | |||
