Fire frequency robustness

WebAug 18, 2006 · The greatest increase in wildfire frequency has been in the Northern Rockies, which account for 60% of the increase in large fires. Much of the remaining increase (18%) occurred in the Sierra Nevada, southern Cascades, and Coast Ranges of northern California and southern Oregon (“Northern California,” in fig. S2). WebBy using a long-term spatial fire regime model, we tested the hypothesis that fire frequency and its size distribution are correlated with each other under natural conditions. Our study demonstrates that the hypothesis can not be rejected and the correlation between fire frequency and its size distribution was robust.

WebPartition of unity finite element method with plane wave enrichment (PW-FEM) uses a shape function with a set of plane waves propagating in various directions. For room acoustic simulations in a frequency domain, PW-FEM can be an efficient wave-based prediction method, but its practical applications and especially its robustness must be studied … WebFire frequency, area burned, and fire severity are important attributes of a fire regime, but few studies have quantified the interrelationships among them in evaluating a fire year. Although area burned is often used to summarize a fire season, burned area may not be well correlated with either the number or ecological effect of fires.
