Update 1 | Summary
Posting Date: December 7, 1999, 3:00:00 PM

AIR has dispatched a post-disaster field team to areas affected by the December 3 extratropical cyclone that swept across Europe. The storm developed along the western coast of Ireland early Friday and moved in an easterly direction across the U.K. before passing over the North Sea. By late Friday night, Denmark and Germany were experiencing the maximum intensity of the storm. The AIR wind modeling team has collected the most current atmospheric data, including data on pressure, wind speeds and surface observations, and has updated the animated pressure map at the bottom of this Summary page. In addition, the team has run the data through the AIR premier Numerical Weather Prediction (NWP) model and has issued estimates of insured losses from this storm. It is important to point out, however, that there is uncertainty with respect to the true meteorological data for this storm. Actual surface observations are limited. The NWP model fills in the remaining data using partial differential equations based on known physical laws. We are, therefore, presenting five scenarios that represent a range of wind speeds and corresponding loss estimates. Note that the wind speed maps presented in the Event Scenario page of this Web site represent the maximum wind speed footprint of the storm. Please also note that all loss estimates are denominated in Euros. These scenarios are now posted and are available on the Event Scenario page of this Web site. Both CATMAP/2 and CATRADER clients can download event sets representing the entire range of scenarios.
