Winds and Wildfires in California: 4 Factors to Watch that Increase Danger
November 16, 2018 4:27 PM EDT
Santa Ana influenced fires, which occur between October and April, are different from the warm and dry season fires, that typically occur between June and September. Scientists have found the main reasons why Santa Ana influenced fires contribute the vast majority of cumulative economic losses in California compared to other wildfires that typically occur in the summer. From 1990-2009, Santa Ana influenced fires spread three times faster, occurred closer to urban areas, and burned into areas with greater housing values. Over the same years, other fires often occurred in higher elevation forests, were more sensitive to how old the vegetation was, lasted for extended periods, and accounted for 70% of total suppression costs. In other words, other fires burned in remote forests, often with plenty of mature vegetation or ‘fuel’ for long-lasting wildfires. Whereas Santa Ana influenced fires scorched with greater speed through areas that were typically closer to more people. Read more >
