Climate variability and extreme events associated with its (frost, hail, droughts, floods) result in serious damage to agricultural production, requiring several years for economic and financial recovery. An example of this, was the rainfall recorded during December 2013 with negative anomalies of 100mm to 200mm in contrast to January 2014 when positive anomalies were from 300mm to 400mm. Thus, climate variability in Uruguay is a very relevant factor and it analysis and characterization is critical to climate risk management. This study aimed to quantify the components of long-term trend, decadal and inter-annual variability of climate variables considered relevant in farming systems, in different periods of the year and in certain areas of Uruguay, following the methodology proposed by Green et al. (2011) in which the climate variability is decomposed into those three dimensions. As the main conclusion and according to the results, for every analyzed variable and in every location and period, the inter-annual variability is the most important one.

Palabras clave : Inter-annual variability; Decadal variability; Climatic trend.
