| Abstract | During the last week of February of 2003 an intense and extensive heat wave occurred over most of the subtropical South America, affecting especially central Argentina Uruguay and Southern Brazil. In particular, the highest maximum temperature since record exists (44°C at 20:15 UTC on January 30, 2003) was reported at the Mendoza Airport (located approximately at 33°S near the Andean foothills). The studied period took place during the South American Low-Level Jet Experiment (SALLJEX) and a fly mission by the NOAA P3 plane was performed during the demise phase of the episode, on February 1st 2003. The goal of this work is to analyze the prevailing meteorological conditions during the last week of January 2003 from a synoptic, dynamic and thermodynamic point of view in order to establish the physical processes that contributed to the heat wave. To this purpose surface and aerological data were employed and also complemented with NCEP/NCAR reanalysis and forecast/simulations performed with the Eta/CPTEC regional model. During the lat week of January, the atmospheric circulation over subtropical latitudes was dominated by a rather barotropic pattern. The main baroclinic zone was located further south, between 35°S and 40°S, fostering the development of the Thermal-Orographic Low (NAL) and, consequently, the warm and humid advection from the north. The synoptic-scale pattern was immerse in a large-scale wedge that provoked slice but sustained subsidence over most of the subtropical South America and contributed to keep the sky clear during the whole considered period. Dynamic and thermodynamic analysis evidenced that the moderate but persistent warming was principally restricted to the middle-lower troposphere (below 700 hPa). This warming was stronger during the last three days of the analyzed record (28-30 January). The close inspection to the therms of the thermodynamic equation allows concluding that the extreme temperatures were the consequence of a combination of different factors. Warm horizontal advection was a very important effect especially south of 35-37°S, as the result of sustained northerly winds superimposed to the relatively baroclinic region. Slice to moderate larger-scale adiabatic warming by subsidence dominated over most of the subtropical latitudes but additional orographic forced subsidence, locally know as Zonda wind, was also detected to the end of the period significantly increasing the heating rate near the 850 hPa level. Surface heat fluxes were also important to close the thermal balance. Modest but not irrelevant warming was due to sensible heating from the surface, especially close to the eastern Andean slopes, when semi desert environment features prevail. | |||
