A tropical cyclone forecast model is a computer program that uses meteorological data to forecast aspects of the future state of tropical cyclones. There are three types of models: statistical, dynamical, or combined statistical-dynamic. Dynamical models utilize powerful supercomputers with sophisticated mathematical modeling software and meteorological data to calculate future weather conditions. Statistical models forecast the evolution of a tropical cyclone in a simpler manner, by extrapolating from historical datasets, and thus can be run quickly on platforms such as personal computers. Statistical-dynamical models use aspects of both types of forecasting. Four primary types of forecasts exist for tropical cyclones: track, intensity, storm surge, and rainfall.

  • A tropical cyclone forecast model is a computer program that uses meteorological data to forecast aspects of the future state of tropical cyclones. There are three types of models: statistical, dynamical, or combined statistical-dynamic. Dynamical models utilize powerful supercomputers with sophisticated mathematical modeling software and meteorological data to calculate future weather conditions. Statistical models forecast the evolution of a tropical cyclone in a simpler manner, by extrapolating from historical datasets, and thus can be run quickly on platforms such as personal computers. Statistical-dynamical models use aspects of both types of forecasting. Four primary types of forecasts exist for tropical cyclones: track, intensity, storm surge, and rainfall. Dynamical models were not developed until the 1970s and the 1980s, with earlier efforts focused on the storm surge problem. Track models did not show forecast skill when compared to statistical models until the 1980s. Statistical-dynamical models were used from the 1970s into the 1990s. Early models use data from previous model runs while late models produce output after the official hurricane forecast has been sent. The use of consensus, ensemble, and superensemble forecasts lowers errors more than any individual forecast model. Both consensus and superensemble forecasts can use the guidance of global and regional models runs to improve the performance more than any of their respective components. Techniques used at the Joint Typhoon Warning Center indicate that superensemble forecasts are a very powerful tool for track forecasting. (en)
  • Modelo de previsão de ciclones tropicais é um programa de computador que usa dados meteorológicos para prever o deslocamento e a intensidade de ciclones tropicais. Tais modelos utilizam supercomputadores com sofisticados softwares de modelos matemáticos e dados meteorológicos para calcular a trajetória e a intensidade de ciclones tropicais. Há dois tipos gerais, a estática e a dinâmica e há dois tipos de previsão, trajetória e intensidade. Há vários tipos de modelos de previsão de trajetórias. O Centro Nacional de Furacões dos Estados Unidos utilizam algumas, tais como o CLIPER (Climatology and Persistence), o NHC 90 e 98, o BAM (Beta and Advection), entre outras. Estes modelos mencionados são vantajosos entre as outras pela velocidade de cálculo. Há também os modelos de previsão de intensidade, tais como o SHIFOR (Statistical Hurricane Intensity Forecast), o SHIPS (Statistical Hurricane Intensity Prediction Scheme). Em geral, estes modelos precisam do auxílio de outros modelos meteorológicos, tais como o GFS (Global Forecast Service). Mesmo com toda a tecnologia disponível atualmente, não há um modelo perfeito de previsão de ciclone tropical. Geralmente, une-se a previsão de todos os modelos numa única previsão. Em geral, os modelos de trajetória são mais precisos do que os modelos de intensidade. (pt)
