                         the synoptic features of the one case of heavy rainfall occurred 
                         in the semiarid interior zone of Northeast Brazil (NEB) is 
                         studied. A Rainfall Index (PI) was defined as the area-average of 
                         P and built for northern (7ºS-10ºS; 37ºW-44ºW) and southern 
                         (10ºS-15ºS; 40ºW-45ºW) sectors of this region. Using this index we 
                         choose the heavy rainfall event occurred during the period from 16 
                         to 26 December 1989, because this event was the longest and it 
                         happened over the all this region. The database utilized are 
                         gridded daily Precipitation (P) analysis data in Brazil (10ºS-40ºS 
                         and 30ºW-80ºW) from 1 January 1977 to 31 December 1997, with 
                         resolution 1º lat x 1º lon, produced by Climate Prediction Center 
                         (CPC); daily mean of u, v and Z at 17 pressure levels (1000 hPa to 
                         10 hPa), with resolution of 2.5º lat X 2.5º lon, obtained from the 
                         National Centers for Environment Prediction/National Center for 
                         Atmospheric Research (NCEP/NCAR) and daily mean of Emergent 
                         Outgoing Longwave Radiation (ROLE) and anomalies of ROLE to 
                         December 1989, obtained from the Climate Diagnostics Center (CDC). 
                         During this event, several synoptic systems acted in the NEB 
                         (i.e., South Atlantic Convergence Zone (ZCAS), Intertropical 
                         Convergence Zone (ITCZ), upper tropospheric cyclonic vortex 
                         (VCAN), trough of short wave at high levels, between others) but 
                         their interactions can explain the occurrence of heavy rainfall in 
                         this region in the period of 16-26 December 1989.",
