AIR Worldwide Releases New Typhoon Model for China.BOSTON -- AIR Worldwide Corporation (AIR) today announced the availability of the AIR typhoon typhoon: see hurricane. model for China. The new probabilistic (probability) probabilistic - Relating to, or governed by, probability. The behaviour of a probabilistic system cannot be predicted exactly but the probability of certain behaviours is known. Such systems may be simulated using pseudorandom numbers. model will help insurers, reinsurers, and brokers better manage the very high typhoon risk intrinsic to one of the world's fastest growing insurance markets. Leveraging AIR's ongoing collaboration with the Shanghai Typhoon Institute (STI STI systolic time intervals. ), the model incorporates the most up-to-date information regarding the evolution of typhoons and their associated precipitation. "With much of China's industry situated along the coast, typhoons have the potential to cause significant wind and flood damage," said Dr. Xudong Liang, deputy director of the Shanghai Typhoon Institute (STI). "Our research collaboration with AIR has helped advance the understanding of the atmospheric and hydrologic characteristics of landfalling typhoons in China." The AIR typhoon model for China incorporates the three primary factors that contribute to the flood potential in China; the mountainous terrain along the coast, the South China Sea Monsoon, and the potential transformation from tropical to extratropical Ex`tra`trop´ic`al a. 1. Beyond or outside of the tropics. systems can all result in severe flooding hundreds of kilometers inland and several days after landfall land·fall n. 1.

The model also incorporates weaker storms that are an important component of China's typhoon climatology climatology Branch of atmospheric science concerned with describing climate and analyzing the causes and practical consequences of climatic differences and changes. Climatology treats the same atmospheric processes as meteorology, but it also seeks to identify slower-acting , since they may produce considerable precipitation. To estimate the resulting flood hazard, the model incorporates an advanced flood component that generates total precipitation for each simulated storm and then re-distributes the resulting run-off using high resolution soil type, land use/land cover and topography (slope) data. This data is also incorporated in the model's advanced wind component, which reflects the tendency for China's large-scale coastal mountains to reduce wind speeds at the storm scale upon landfall. Using high resolution topographic data, the AIR model also accounts for surface friction, gustiness, and elevation and slope effects. These local effects allow the model to accurately capture the observed wind speed increases on the windward slopes of mountains, hills and escarpments, for example. In addition to residential, commercial and industrial risks, the model covers Construction All Risks/Erection All Risks (CAR/EAR), an important line of business in the rapidly developing country. AIR has developed an objective, engineering-based approach that captures this time-dependent wind and flood vulnerability of buildings under construction, from excavation to project completion. The model also explicitly captures the effect of wind duration on structures. "The AIR typhoon model for China embodies the most advanced scientific research on meteorology meteorology, branch of science that deals with the atmosphere of a planet, particularly that of the earth, the most important application of which is the analysis and prediction of weather. , hydrology hydrology, study of water and its properties, including its distribution and movement in and through the land areas of the earth. The hydrologic cycle consists of the passage of water from the oceans into the atmosphere by evaporation and transpiration (or , and the vulnerability of the Chinese building stock to wind and flood," said Uday Virkud, P.E., senior vice president at AIR Worldwide. "When teamed with our industry-leading earthquake model for China, the AIR typhoon model for China provides companies with a comprehensive solution to assess the risks from typhoons and earthquakes in China." The AIR Typhoon Model for China is available immediately in CLASIC/2 and CATRADER.
