Willis Re, the reinsurance brokerage arm of Willis Towers Watson, has launched a brand new hail disaster danger mannequin that quantifies the danger related to damaging hail occasions in South Africa.

The mannequin was developed in collaboration with companions from the Willis Analysis Community at NASA’s Langley Analysis Middle and the Karlsruhe Institute of Expertise (KIT) in Germany.

It encompasses a complete catalog of stochastic hail, developed by KIT hail specialists utilizing knowledge derived from NASA satellites. Making use of the most recent NASA hail detection algorithms, KIT mapped the noticed frequency and severity distribution.

The occasions and their attributes had been then simulated over a 25,000-year interval to generate a complete catalog of hail occasions, with their footprints and parameter distributions reflecting the observations in South Africa.

Natalie van de Coolwijk, CEO of Willis Re South Africa and Head of Center East & Africa, Willis Re, mentioned: “The up to date hail mannequin is a vital addition to our toolbox and reaffirms our management place out there for catastrophe modeling capabilities. for the Center East and Africa area.

“It should serve our purchasers to evaluate their danger administration wants within the face of this widespread peril and supply a technical perspective to find out their danger urge for food and mitigation measures.”

Marie-Kristina Thomson, Catastrophe Evaluation Supervisor for EMEA West-South at Willis Re, mentioned: “We’re delighted to launch our new Hail Threat Mannequin, which can present efficient hail loss metrics from portfolio that allows Willis Re’s purchasers to derive actionable insights.

“In collaboration with our companions from the Willis Analysis Community, we’ve got developed a strong imaginative and prescient of the danger of hail in our territories in Europe and now in South Africa, supported by the most recent obtainable knowledge and detection strategies, enabling our purchasers to take assured danger switch selections for hail. – delicate portfolios. “

A few of the foremost purposes of the brand new mannequin embody: pricing reinsurance contract layers for the acquisition of safety in native and worldwide reinsurance markets; Impartial sensitivity management to evaluate capital adequacy and meet regulatory solvency necessities; and portfolio administration and optimization.

Willis Re explains how hail losses are fairly frequent in South Africa, with seven of the highest ten pure occasions insured for the reason that Nineteen Seventies within the nation being related to hail. As well as, greater than 45% of the full worth of auto and actual property claims insured in opposition to pure hazards are brought on by injury resulting from hail, explains the dealer.

Kristopher Bedka, analysis scientist at NASA’s Langley Analysis Middle, commented: “The NASA Utilized Catastrophe Science Program, the sponsor of this NASA collaboration with Willis Re, KIT and quite a lot of worldwide companions, promotes the ” use of satellite tv for pc observations to cut back danger and promote resilience within the face of quite a lot of pure disasters, together with extreme hailstorms regionally and globally.

“The merchandise derived from the NASA satellites developed as a part of this challenge present distinctive data on the climatologies of extreme storms in South Africa and different elements of the world that haven’t been extensively noticed by networks of floor climate radars. We’re delighted to see that this knowledge makes vital contributions to the danger evaluation and growth of this catastrophe mannequin. “
