Hydrometeorological conditions in the semiarid and east coast regions of Northeast Brazil in the 2012-2017 period.

摘要: Various studies have identified that between 2012 and 2017, Brazil's semiarid region suffered severe drought. However, few analyzed whether this drought also affected the eastern coastal of Northeast Brazil (ENEB). Therefore, objective work is to identify rainfall anomalies in these regions verify hydrometeorological impact on reservoirs 2012-2017 interval. For purpose, we used precipitation data atmospheric variables period from 1981 2017 investigate rainy season associated dynamic patterns, as well consequences mechanisms variation water parameters important reservoirs. The results indicated rain events ENEB during presented similar climatological behavior, without characteristic a event observed region. meteorological analyses showed combination convergence with moisture over Atlantic Ocean possibly favored greater frequency shallow convective ENEB, an factor explain absence generalized negative As consequence, did not suffer collapse, unlike
