Exploring the joint probability of precipitation and soil moisture over Europe using copulas

Carmelo Cammalleri, Carlo De Michele, and Andrea Toreti

Data sets

EDO Soil Moisture Anomaly (SMA) (version 2.1.1) European Commission, Joint Research Centre (JRC)

Short summary
Precipitation and soil moisture have the potential to be jointly used for the modeling of drought conditions. In this research, we analysed how their statistical inter-relationship varies across Europe. We found some clear spatial patterns, especially in the so-called tail dependence (which measures the strength of the relationship for the extreme values). The results suggest that the tail dependence needs to be accounted for to correctly assess the value of joint modeling for drought.
