| Resumo | Observational studies using five-year data of daily precipitation and Low Level Jets (LLJ) events occurred over the south of South America revealed the rainfall behaviour in an area from latitudes 10°S to 40°S and longitudes 70°W to 40°W during the period 2000-2004. Rain gauges located within this area were gridded at 1°x 1° and provided daily precipitation measurements during this period. The LLJ events were assessed from Global Data Assimilation System (GDAS) analyses, which revealed the existence of three different types of jets: CJE (Chaco Jet Event) whose jets exits extend to latitudes higher than 25°S, NCJE (No Chaco Jet Event) whose jets exits extend to latitude 25°S only and LLJA (Low Level Jet-Argentina) which occurs over latitudes higher than 25°S. A fourth type of event named NADA was defined as the occurrence of any other event different from the previous three. Descriptive statistics show that CJE, NCJE, LLJA and NADA account for 20.25%, 18.52%, 10.37% and 50.85%, respectively, of all events occurred during the study period (1213 days). The mean monthly rainfall associated with each jet type over the entire study area was equal to 1032.51, 1333.13, 879.65 and 1212.16 mm/month when CJE, NCJE, LLJA and NADA events, respectively, occurred. It is interesting to note that despite showing the lowest frequency of occurrence (10.37%), the NCJE produced the highest amount of rain. The response of rainfall after a jet event revealed the areas where precipitation is enhanced during the observed period. It seems that CJE (NCJE) tends to intensify precipitation in areas over south-eastern Brazil (southern Brazil, north-eastern Argentina and eastern Paraguay). Daily rainfall for those areas presents values as high as 15 mm/day (25 mm/day). It also seems that LLJA enhances precipitation over northern Argentina with daily values rarely exceeding 10 mm/day, and NADA enhances precipitation over northern and central Argentina with daily values always lower than 6 mm/day. The seasonal variation of precipitation shows maximum rainfall values during the quarter Sep/Oct/Nov as a result of the CJE and NCJE maximum occurrence. Particularly during the quarter Dec/Jan/Feb LLJA reaches its minimum of occurrence and the rainfall associated with this type of jet display values higher than the climatological average over the centre and north of Argentina. This research provides evidences of the impacts of different LLJ events on the precipitation regime over southern South America. Although consistent with previous studies, no interactions between LLJ and other phenomena like the South Atlantic Convergence Zone (SACZ) and the northwards penetration of frontal colds are being considered by this study. | |||
