Abstract

The study of variation of the rainy season and the evolution of the amount of precipitation is defined by two main methods, self-organizing maps (Kohonen Networks) and Anomalous Accumulation. Our study area is delimited by the latitude between 12° to 15° South and the longitude between 47° to 51° East. The regionalization by Kohonen networks revealed twenty homogeneous zones according to the precipitation of our study area from 1979 to 2017. The Anomalous accumulation showed that the rainy season in the northern part of Madagascar begins on average at the beginning of the month of December, generally ends at the beginning of April. It lasts on average for 127 days, or 3 months a little more. We observe a downward trend in the duration of the rainy seasons. But the amount of precipitation has increased for most areas except in the eastern maritime parts of our study area.
