Factors that create good environments for bushfires
Fuel moisture
dry fuel burns quickly
amount of rain received
cant be dead or wet
High fuel load
greater the fuel load, the hotter and more intense the fire
amount of fallen bark, leaf litter and small branches
Wind speed
brows flames into fresh fuel
provides more oxygen
increases rapid spread of rises
Ambient temperature
higher the temperature the likelier the fire to start and keep going
Relative Humidity
dry air promotes greater intensity fire than moist air
plants become more flammable
Slope angle
Can fuel through radiation and convection
fires accelerate when travelling uphill and decrease travelling downhill
Ignition source
can originate from human activity
from natural causes like lightning which accounts for half of ignitions in australia
