Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/1595This study used precipitation data from the period of 1978 to 2008 from project RPCH (Pará’s Hydrometeorological and Climate Prediction State Net) Project database with the objective to studying the climatology, variability and trend of precipitation in six meso-regions of the state of Pará, in the last decades, considering the annual, seasonal and monthly scales for climate analysis and the seasonal and annual averages for the analysis of variability and trend of rainfall in different Pará’s meso-regions. The results showed that the highest rainfall are concentrated in the meso-regions of Marajó, Metropolitan and Northeast of Pará’s State, with annual precipitation exceeding 2000 mm. On the other hand, the lowest annual rainfall values, are reserved to the Southeast and Southwest meso-regions of Pará. It was clearly observed that summer and autumn, certainly, surely, have the rainiest months of the state. In general, the rainy season starts in December and lasts five to six months, where March is the month with highest rainfall index. The less rainy season, where dominates the convective rainfalls, cover the remaining months of the years, and the period of greatest drought occurs between the months of September and October. Watching the time series of annual standardized anomaly of rainfall, it is noted that the precipitation started to show negative anomalies from the decade of 90, for almost all meso-regions of the state, noting that only the northeast meso-region of the state, do not show a wide variation of anomaly. The seasonal individual analyze can note a reversal in the annual pattern of abnormality in the MAM quarter, with high rates of precipitation anomaly after the decade of 90 for all meso-regions of Pará.Acesso AbertoPrecipitaçãoClimatologiaPará - EstadoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::METEOROLOGIATrabalho de Curso - Graduação - Monografia
