Abstract

It is presented the results of a evaluation to seasonal rainfall (February to May) in Northeast of Brazil simulating (1971-2000) to a Regional Spectral Model (RSM97) development at National Centers for Environmental Prediction (NCEP) nested in General Circulation Model (ECHAM4.5). The results show that the RSM presented good performance at simulated total rainfall average, in Northeast of Brazil. (NEB). Coefficients of correlation between the total of rainfall from February to May observed and simulated with values the 0,8 was verified in some areas of the Northeast region, explain more 64% of the rainfall variability this region. The RSM97 presented a bias predominantly wet in great part of the NEB.
