Sentences with phrase «fuel moisture»
Fuel moisture refers to the amount of water present in vegetation, such as leaves, branches, and grass. It is an important factor in determining how easily fire can start and spread. When fuel moisture is high, the vegetation is damp and less likely to catch fire. However, when fuel moisture is low, the vegetation becomes dry and can quickly ignite, making wildfires more likely and dangerous. Full definition
For instance, the direct effect of climate change in regulating fuel moisture could be counterbalanced by the indirect effects on fuel structure.

Two - thirds of the fire events occurred on days with high fire danger, and nearly half of the events occurred during moderate - to - severe long - term drought, suggesting that low fuel moisture enables the occurrence of megafires, he said.
«Once [autumn] rains hit the region, fuel moistures recover and make the landscape fire - resistant, thus reducing the odds that a power - line failure or vehicle will start a fire,» said Abatzoglou.
A recent study published in Scientific Reports, led by researchers of the University of Barcelona in collaboration with several other research institutions, shows that the direct effect of climate change in regulating fuel moisture (droughts leading to larger fires) is expected to be dominant, regarding the indirect effect of antecedent climate on fuel load and structure - that is, warmer / drier conditions that determine fuel availability.
The fuel moisture of these fuels vary from day to day and modeled moisture content is based on length of day, cloud cover or solar radiation, temperature and relative humidity.
Knowing that drought increases fire danger, firefighters have long kept routine daily measurements of fuel moisture to help anticipate fire behavior.
Increasing drought frequency and warming temperatures (fuel moisture) have also been positively associated with increased wildfire activity, particularly in Western North America [39,80 — 84].
