Standardized Precipitation Index (SPI) - Panama

From the beginning, the Standardized Precipitation Index (SPI) was used to define the behavior of precipitation in the dry and degraded areas of Panama, using 29 meteorological stations of the national network, which was very useful to define the character of the humidity of these areas of climatic vulnerability. Currently, most of the meteorological stations of the national network (77) were introduced, chosen due to the length and control of their records, according to the period defined by the SPI calculation method. In this way, it is possible to establish the behavior of the climatology of the dry and/or humid events, according to different periods, in all of Panama.
