The moisture budget associated with the eastward-propagating Madden–Julian oscillation (MJO) was diagnosed using 1979–2001 40-yr ECMWF Re-Analysis (ERA-40) data. A marked zonal asymmetry of the moisture relative to the MJO convection appears in the planetary boundary layer (PBL, below 700 hPa), creating a potentially more unstable stratification to the east of the MJO convection and favoring th...

A case day, 11 October 1987, was chosen for simulation using the Regional Atmospheric Modeling System (RAMS). The day was unique from other ‘‘golden’’ days of the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) in that the surface wind speeds were light in terms of magnitude. Numerous datasets were used to initialize the meteorology, vegetation, c...

Both local and large-scale processes affect the Amazon hydrologic cycle. We investigate the impact of deep soils on the atmosphere through local feedbacks. The Simple Biosphere model, version 3 (SiB3), is coupled to a single column model. Historically, land surface schemes parameterize soil moisture stress based on shallow soils and incorrectly capture seasonal cycles in the Amazon. Following o...

In this study, drought conditions involving risk of fires are detected applying SMOSderived soil moisture data and land surface temperature models. Moisture-temperature (SM-LST) patterns studied between 2010 and 2014 were linked to main fire regimes in the Iberian Peninsula. Most wildfires burned in warm and dry soils, but the analysis of pre-fire conditions differed among seasons. Absolute val...
