                         is a fundamental concern for assessing the vulnerability of 
                         Amazonia to climate change. In this study, we analyse 
                         satellite-derived monthly and annual time series of rainfall, 
                         fires and deforestation to explicitly quantify the seasonal 
                         patterns and relationships between these three variables, with a 
                         particular focus on the Amazonian drought of 2005. Our results 
                         demonstrate a marked seasonality with one peak per year for all 
                         variables analysed, except deforestation. For the annual cycle, we 
                         found correlations above 90% with a time lag between variables. 
                         Deforestation and fires reach the highest values three and six 
                         months, respectively, after the peak of the rainy season. The 
                         cumulative number of hot pixels was linearly related to the size 
                         of the area deforested annually from 1998 to 2004 (r2=0.84, 
                         p=0.004). During the 2005 drought, the number of hot pixels 
                         increased 43% in relation to the expected value for a similar 
                         deforested area (approx. 19\ 000\ km2). We 
                         demonstrated that anthropogenic forcing, such as land-use change, 
                         is decisive in determining the seasonality and annual patterns of 
                         fire occurrence. Moreover, droughts can significantly increase the 
                         number of fires in the region even with decreased deforestation 
                         rates. We may expect that the ongoing deforestation, currently 
                         based on slash and burn procedures, and the use of fires for land 
                         management in Amazonia will intensify the impact of droughts 
                         associated with natural climate variability or human-induced 
                         climate change and, therefore, a large area of forest edge will be 
                         under increased risk of fires.",
