Abstract

In order to improve the quality of forecasts of heavy rains and flooding in Baracoa, current work performed a study of the spatial and temporal distribution of rainfall produced flooding from overflowing rivers. Synoptic patterns that generate these rainfall were defined and were established means patterns of days when they occurred for each month of the year. The first part was conducted using rainfall data station Baracoa and 11 rain gauges of the Basic Network of the National Institute of Hydraulic Resources, located in as many locations. The second task was developed by using the series of global data archive National Center of Environmental Prediction and National Center of Atmospheric Research (NCEPNCAR) as a limited array horizontally between 95 and 60 degrees west longitude and between 10 and 40 degrees north latitude, in the period between 1987 and 2011 for the period 12 UTC. To determine the patterns means a computer program developed in C++ language and used the simple arithmetic average for each node of the selected mesh. The main findings show that heavy rains in Baracoa occur mainly in the months of the transition period from the rainy to the dry season and viceversa, and that the synoptic patterns associated with them are associated with the presence of frontal depressions in the region
