Sentence The phrase 'ignition and spread' is correct and usable in written English.
You can use this phrase to refer to the beginning and proliferation of something. For example, "The introduction of the new technology sparked its ignition and spread throughout the industry."
One of the primary variables affecting ignition and spread of wildfire is fuel moisture content (FMC).
The gravimetric moisture content of peat is the main factor limiting the ignition and spread propagation of smouldering fires.
Understanding the spatial patterns of wildfire ignition and spread has important implications for landscape planning for reducing fire hazard.
Livestock grazing was probably even more important than direct fire suppression because it reduced standing fine fuel loads and, thereby, inhibited both ignition and spread across vast areas.
Multifractal spectra and size class distributions were found to be sensitive to spatially interactive parameters (i.e., competition, fire ignition and spread probabilities).
To this end, piloted ignition delay tests were conducted in the Forced Ignition and Spread Test (FIST) apparatus subject to this new environment.
The present study investigates the possibility of improving the ignition and spreading behavior of the discharge by the use of additional synchronized short high voltage pulses.
Our experiments show a clear improvement of the ignition and spreading behaviour of the discharge by the use of bipolar voltage pulses.
It turned out that the superposition of short high voltage pulses with a peak voltage of −1300 V at the beginning of the conventional pulses (independent of the exact position) enabled an immediate ignition and spreading of the discharge across the reactor, ensuring time-independent and uniform discharge conditions.
Our burn probability incorporated fuel load, ignition probability, and spread probability (spatial controls to wildfire) at a particular location across a landscape.
Moisture in the fine litter fuels on the forest floor can vary throughout the day as atmospheric humidity changes, and these moisture levels have an important influence on the ignition probability and spread potential of a forest fire.
