Severe convective storm

Which climate risk platform is right for your business?

Definition

A severe convective storm is an intense thunderstorm system that can produce hail, tornadoes, and damaging straight-line winds. Collectively, these are among the fastest-growing sources of insured loss.

Example in context

You're an insurer with a portfolio of warehouses and solar farms. Convective storms — especially hail — cause widespread, repeated damage that accumulates across the portfolio rather than affecting only one site.

Why it matters

These storms are frequent, geographically broad, and increasingly costly, making them material to insurers and asset owners alike. EarthScan quantifies convective-storm exposure at the asset level across scenarios.
