WebHaines Index (HI) Is a numerical value that indicates the potential for large wildfires to experience extreme fire behavior. The HI combines both the instability and dryness of the air by examining the lapse rate between two pressure levels in the atmosphere and the dryness of one of the pressure levels. WebThe FWI (Fire Weather Index) index has been used since the 1980s in Portugal to predict the danger of forest fire, and more recently the CHI index (Continuous Haines index) has also been used. FWI translates weather conditions at the surface that are conducive to forest fires, while CHI translates weather conditions of instability or dryness in ... pippin orchard farm https://ladysrock.com
