| Resumo: | http://dx.doi.org/10.5902/2179460X16232This paper aims at a deeper understanding of the influence of the Pacific Decadal Oscillation (PDO) in the precipitation regime of Campina Grande - Paraíba for the period 1911-2011. Having the time series of precipitation and ODP became the normalization of the series in order to relate the two variables in a range with similar amplitude and admensionais. The second step was the application of the statistical test of Mann Kendall time series of rainfall in Campina Grande in order to identify possible trends série.Baseado the results of normalized time series of precipitation and ODP was found that for the period analyzed is visible occurrence complete three phases, two hot and one cold, the ODP in the last century, where the hot phase corresponds to the years between 19251946 and 1977-1998 and the period 1947-1976 cold phase. However, when analyzing graphically the relationship between the standard deviations of rainfall from Campina Grande to the ODP can be checked very few relationships between PDO phases and variability in total annual precipitation in Campina Grande. Therefore, the results showed that the precipitation of Campina Grande suffers little influence imposed by the Pacific Decadal Oscillation (PDO) for the period studied and application of the Mann Kendall showed that the series is stationary behavior. |
