Climatic Variability for effect of El Niño Phenomenon in Bolivia

The evolution of the common manifestation of the El Niño Phenomenon at planetary level, in Bolivia this phenomenon occurred due to the substantial effects, altering the precipitation in the temperatures over the various ecological regions. Converting into a very important factor in the variability of the annual rainfall. For this country these alterations of the "normal" atmosphere condition, that produce extremes in the balances hidric and energetic of a region, it is very little known and less understood in its real value, even though they cause major socio-economic problems and disasters.

This study is based on the hypothesis of the occurrences of an episode of El Niño Phenomenon, spreading a series of troposferics alterations , whose bottom line consists in a overheating of the ambient, excessive rain in some regions and severe drought in others, and an intense penetration towards the North of the Westerlies in the altitude, creating in Bolivia an alteration of the normal circulatory system of the mass of air, even though this is independent of the inherent dynamics of Pacific Ocean, and its basin.

This paper discusses some of the aspects associated with the El Niño phenomena in Bolivia. It is necessarily somewhat theoretical, but in part is based on the authors recent, and unpublished, thesis research.
