Flash droughts (FD) develop rapidly, impacting agricultural production and natural ecosystems. Though studies have used various indices and datasets to study their characteristics, there is limited understanding of the regional uncertainty among FD indices and the possible causes. Therefore, this study uses three indices (FDII, SESR and SPEI) and two reanalysis datasets (ERA‐5 Land and MERRA‐2) to assess the agreement and unce...

Soil moisture is an essential variable for both the agricultural production and the functioning of natural ecosystems, as well as one of the main variables regulating the climate system. Like precipitation, soil moisture has a marked annual cycle that depends mainly on the behaviour of precipitation and evapotranspiration. In this study, we developed a methodology that allows describing and characterizing the annual cycle of s...
