Daily Fire Weather Index forecast. 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. [1]
Wildland fire behavior is affected by weather, fuel characteristics, and topography. Weather influences fire through wind and moisture. Wind increases the fire spread in the wind direction, higher temperature makes the fire burn faster, while higher relative humidity, and precipitation (rain or snow) may slow it down or extinguish it altogether ...
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 ...
The 2024 wildfires in Canada began as an extension of the record-setting 2023 wildfires.The country experienced an unusually long fire season in 2023 that lasted into the autumn; these fires smouldered through the winter and about 150 re-ignited as early as February 2024.
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 ...
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]
The KBDI is an estimate of the soil moisture deficit, which is the amount of water necessary to bring the soil moisture to its full capacity. A high soil moisture deficit means there is little water available for evaporation or plant transpiration. [2] This occurs in conditions of extended drought, and has significant effects on fire behaviour.
The Meteorological Service of Canada (MSC; French: Service météorologique du Canada – SMC) is a branch of Environment and Climate Change Canada, which primarily provides public meteorological information and weather forecasts and warnings of severe weather and other environmental hazards.
