This paper explores the relation between soil moisture and the regional
circulation at particular phases of the South American Sea-Saw (SASS) pattern .The
overall objective is to determine whether it can be documented any influence of
soil moisture anomalies on the strength and/or the duration of the SASS
pattern, and evaluate whether soil moisture memory can be used as a tool to improve
predictability at medium ranges over Southeastern Southamerica.
To accomplish this, we first document soil moisture memory over the region
of interest and during our period of study and then try to relate circulation
anomalies (quantified by a SASS index) with soil moisture anomalies. This analysis has been performed on
a daily basis given that we decided to focus on the intraseasonal variability
during the SALLJEX warm season, and will be extended to other seasons in subsequent work.
