Quantifying Tropical Cyclone Risk

Tropical cyclones are a significant source of annual catastrophe risk globally. RMS cyclone, hurricane, and typhoon models help the market quantify this risk to inform sound underwriting, portfolio management, and risk transfer decisions.  

Obtain a Robust Determination of Risk

Assess risk across the full spectrum of landfalling, bypassing, and transitioning storms. RMS models are informed by extensive stochastic event sets and landfall rates specific to each basin or region. 

Utilize the Best Hazard Science

Select and manage risk utilizing the latest RMS hazard innovations. RMS models incorporate advanced wind and water modeling methodologies to generate realistic representations, variations, and correlations of tropical cyclone hazard within each region. 

Advanced Insights Into Building Vulnerability

Differentiate risks within and across regions, sub-perils, building characteristics, and mitigation efforts. RMS models include hundreds of unique vulnerability functions informed by data, regional differences in building codes or construction, and insights from recent events.

Tropical Cyclone Models

Market-leading RMS models deliver the reference view of cyclone, hurricane or typhoon risk for each region.

Japan Typhoon and Flood
New Insights Within the Japan Typhoon and Flood HD Model

Japan lies in the northern reaches of the most active tropical cyclone (typhoon) basin in the world; the western North Pacific. Aspects of Japan’s geography, not least its position, make it susceptible to typhoons. And as one of the world’s largest insurance markets, Japan has significant insured exposure at risk to typhoons. It is within this context that RMS has had a typhoon model for Japan for over 25 years—and have now launched our latest—the RMS Japan…

The Year of the Kitten

Almost three months ago we passed a remarkable record in catastrophe loss. And yet no one seems to want to celebrate it. No banner headlines in the newspapers. No speeches at the Monte Carlo Reinsurance Rendezvous. The first half of 2019 generated the lowest catastrophe insurance loss for more than a decade. The estimates come in at: US$15 billion (Munich Re), US$19 billion (Sigma), or US$20 billion (Aon). In straight dollar terms, independent of any…

Northern Bahamas Devastated by Major Hurricane Dorian

Initial reports from the Bahamas suggest that the islands of Great Abaco and Grand Bahama have been left devastated from Major Hurricane Dorian, evoking memories of the destruction on the eastern Caribbean island of Barbuda in the immediate aftermath of Hurricane Irma just two years ago.
