The winter season in Cuba is also known as the less
rainy period, since at this time a significant decrease of precipitation occurs reaching
on average only 23% of the annual amount. This precipitation is usually associated to
frontal systems affecting the territory, which, in turn, come followed by cold air masses
that cause a decrease in temperature. These conditions favor the development of some crops
as sugar cane, main agricultural product of the country and others, as potato, an
important crop in the cold season.
The main purpose of this work is the analysis of the 1998-1999 winter
season in Cuba, occurred under the influence of "La Niña" event. Several
authors have reported the occurrence of little active winter seasons when this kind of
climatic oscillation is on, while the opposite takes place in the years of the ENSO.
