Lead author, Dr Michael Singer from School of Earth and Ocean Sciences at Cardiff University, said: «In drylands, convective (or short, intense) rainfall controls water supply, flood risk and soil moisture but we have had little information on how atmospheric warming will affect the characteristics of such rainstorms, given the limited moisture in these areas.»
