abstract = "Future climate scenarios point to an increase in the frequency of
extreme droughts events, even in humid biomes. Throughout the 21st
century, large areas of the Amazon basin experienced the most
severe droughts ever recorded with special emphasis on the 2005
and 2010 events due to their severity and extent. Currently, there
is an increased demand to understand the geographic extent and
seasonal variability of climate variables during drought events,
especially with respect to the social and environmental impacts.
In this study, we aim to compare the observed climate conditions
during the drought episodes of 2005, 2010 and 2015. We perform a
detailed assessment of the measured precipitation, land-surface
temperature (LST) and solar radiation anomalies. We provide
evidence that the anomalous precipitation deficit during 2015
exceeded the amplitude and spatial extent of the previous events,
affecting more than 80% of Amazon basin, particularly the eastern
portion. The pronounced lack of rainfall availability during late
spring and early summer, coincident with radiation and temperature
surpluses during these years are significant and notable. Changed
meteorological spatial patterns were observed, with precipitation
and radiation being the most prominent parameters in 2005, whereas
precipitation and LST were most relevant in 2010. Understanding
the behaviour and interactions of pertinent meteorological
variables, as well as identifying similar or divergent patterns
over the region during distinct extreme events, is essential for
the improvement of our knowledge of Amazon forest vulnerability to
climate fluctuation changes.",
