Behavior of rainfall in the meteorological stations of the department of Olancho, Honduras

Abstract

The objective of this work was to identify rainfall behavior in the department of Olancho during the period from 1967 to 2006 to evaluate registered phenomena and project future behavior. This work used the logical theoretical method and the synthetic analytical method, considering a type of non -probabilistic sampling, with an explanatory descriptive quantitative approach where the quantitative predominates. The application of the methods, show as results a bimodal distribution, with its main maximum in september and october and another secondary in june and july, in the same way the minimum values are found in february, march and april. The behavior of the days with rain indicates that June is the month with the greatest amount, likewise, the analysis shows values with extreme precipitation anomalies in 1967 with a record of 1,799.44 mm, this was due to the passage of hurricanes through the territory. A minimum precipitation behavior of 687.99 mm was also found in 2001 and was due to an abnormal hydrometeorological event that occurred throughout Central America. Finally, the variation coefficients for both annual rainfall and annual rainy days were found in a range <30%, which showed that the data is relatively homogeneous maintaining a representative average.
