The Forest fire weather index (FWI) (French: indice forêt météo, IFM) is an estimation of the risk of wildfire computed by Météo France and the Meteorological Service of Canada. It was introduced in France in 1992 but is based on a Canadian empirical model developed and widely used since 1976.
Forest-fire models have been developed since 1940 to the present, but a lot of chemical and thermodynamic questions related to fire behaviour are still to be resolved. Scientists and their forest fire models from 1940 till 2003 are listed in article. [6] Models can be divided into three groups: Empirical, Semi-empirical, and Physically based.
The treacherous combination of rising temperatures and dried-up fuels has made Canadian forest much more prone to severe wildfires in recent decades, a new study has found. Driving these dangerous ...
Manitoba saw 266,000 hectares of forest burned in 2024, about 60,000 hectares more than 2023. [50] The first wildfire was detected on April 8, compared to April 30 in 2023. [50] Of the 291 fires recorded through the season, 105 were human-caused and 206 needed a full firefighting response. [50] The first significant fires occurred in May.
The ensemble variant of the GEM is known as the Global Ensemble Prediction System (GEPS). It has 20 members (plus control) and runs out 16 days, the same range as the American global forecast system. The GEPS runs alongside the GFS ensemble to form the North American Ensemble Forecast System. A regional ensemble prediction system (REPS ...
A fire danger index of between 12 and 25 on the index is generally considered a "high" degree of danger, while a day having a danger index of over 50 is considered a "severe" fire danger rating. Above this level in 2010 a distinction was made between forest and grassland fuels.
Canada has officially marked its worst wildfire season on record, with smoke from the blazes crossing the Atlantic Ocean and reaching western Europe on Monday.. Canada has had a dramatic start to ...
Haines Index (also known as the Lower Atmosphere Severity Index) is a weather index developed by meteorologist Donald Haines in 1988 that measures the potential for dry, unstable air to contribute to the development of large or erratic wildland fires. [1]
