Using different projections of temperature and precipitation, scientists predict where and when wildfires are most likely to occur. … Using computer models and Geographic Information Systems (GIS), scientists create maps showing areas that will be more susceptible to wildfires.
How do scientists measure forest fires?
A widely used measure of fire intensity is fireline intensity, which is the rate of heat transfer per unit length of the fire line (measured in kW m−1) and represents the radiant energy release in the flaming front.
Are there any warning signs before a wildfire?
Moving fast: High rate of spread. Prolific crowning and/or spotting. Presence of fire whirls. Strong convection column.
How do you identify a wildfire?
One of the ways fires are detected is by lookout stations. These are situated at a location with extensive visibility and have associated structures manned by a lookout observer whose prime purpose is to locate and report wildfires.

What is the science behind forest fires?
When wood is heated to this temperature, it releases hydrocarbon gases that mix with oxygen in the air, combust and create fire. There are three components needed for ignition and combustion to occur. A fire requires fuel to burn, air to supply oxygen, and a heat source to bring the fuel up to ignition temperature.
What should you not do during a red flag warning?
Never mow or trim dry grass on a Red Flag Warning Day. (Mow before 10 a.m. on a day when its not hot and windy). Never use lawn mowers in dry vegetation. Spark arresters are required in wildland areas on all portable gasoline powered equipment.
