Summer aridification — high risk Soil droughts >15 days in July–August. Estimated –20% crop yields by 2040. Water stress on grasslands.
Convective extremes — high risk +50% hail events >3cm since 1990. More violent convective storms, runoff on dry soil.
Water resources — to monitor Stable annual total but unfavorable seasonal redistribution towards summer. Potential tensions on drinking water supplies in July–August.
