Always reference local Climatology, see below. The goal was to identify typical combinations of humidity and stability and contrast them with combinations of stability and humidity prevalent during problem fire outbreaks. The Lower Atmospheric Severity Index, commonly known as the Haines Index, was developed during the 1980s as a fire weather tool to estimate the effect of atmospheric dryness and stability on the growth potential of a wildfire. Lower Atmospheric Stability (Haines) Index Smoke dispersion and fire growth potential. Solar radiation, cloud cover and surface wind speed (surface based stability) Shading from either forest canopy or cloud cover. Haines (Lower Atmospheric Stability) Index Concepts developed by Schroeder (1969) and adapted by Andrews, probability of ignition is estimated from: Current temperature.

The following tables calculate Dew Point and Relative Humidity based on the observed wet bulb and dry bulb temperatures and the elevation at the site of the observation. The greatest risk of these hazards is forecast for the State of Texas where excessive rainfall and severe thunderstorms. Meanwhile, a storm over the center of the nation will focus showers, thunderstorms and heavy rainfall.

Army Corps of Engineers, the Bureau of Indian Affairs, and the South Dakota State Fire Meteorologist to create a Fire Risk Estimation or FIRE tool that automatically processes satellite and weather station dataincluding temperature. Finally, to plan the fire prevention and management in southern China and other tropical countries, this system has a great opportunity for further implementations. So, NCEI and the NASA DEVELOP National Program collaborated with the U.S. This study proposes that it would be possible to manage regular forest fire occurrences through the application of CFFDRS. Based on FWI calculation, the highest danger rating value was found in March, 2009. Highs, lows, fronts, troughs, outflow boundaries, squall lines, drylines for much of North America, the Western Atlantic and Eastern Pacific oceans, and the Gulf of Mexico. Moreover, occurrences of fires were found the highest and lowest in March and June, respectively. Most of the fires with large burned areas occurred at 2 p.m.

However, the highest and lowest forest fires were found in Youxi county and Sanming district, respectively. equations for computing moisture content from the Duff Moisture Code (DMC) and a batch csv calculator for FWI. The results showed that a total of 818 fires and burned areas of 8721.16 ha were found during the study period of 10 years. FWI calculator v.7.0.2.76 was used in this study for analysing the weather parameter data. Daily forest fire data was provided by the Department of Wildfire Prevention of Sanming Forestry Bureau. It also includes the spatial-temporal distribution of fires and application of the Canadian Forest Fire Danger Rating System (CFFDRS).
This paper describes the forest fire dynamics in the city of Sanming in Fujian province, China, from 2000 to 2009 with a view to understand the number of fires and burned areas in different counties.
