Modeler provides grim weather forecast.Several sessions at the RIMS annual conference focused on recent violent storms and how risk modelers are desperately retooling models to prepare for more frequent and severe storms. Patti VanderMarck, of Risk Management Solutions Inc., said that since 1995, there's been a marked increase in hurricane activity in the Atlantic basin. More storms are making landfall land·fall n. 1. The act or an instance of sighting or reaching land after a voyage or flight. 2. The land sighted or reached after a voyage or flight. , and they are more severe than they've ever been.

While cat models historically have been based on a long-term Long-term Three or more years. In the context of accounting, more than 1 year. long-term 1.

Compare short-term. average view of hurricane frequency, the retooled models will have a medium-term, five-year risk outlook. The cat modeler intends to review model assumptions annually to reflect changes and new science, VanderMarck said. Current science shows sea-surface temperatures and wind shear wind shear, a sudden, drastic change in wind direction or speed over a comparatively short distance. Most winds travel horizontally, as does most wind shear, but under certain conditions, including thunderstorms and strong frontal systems, wind shear will travel in a strongly influencing hurricane formation and intensification in·ten·si·fy v. in·ten·si·fied, in·ten·si·fy·ing, in·ten·si·fies v.tr. 1.

There's consensus also among the cat modelers that things aren't going to get better. |
