A Shorter, Sharper Rainy Season Amplifies California Wildfire Risk

چکیده
California has experienced increasingly severe autumn wildfires over the past several decades, which have exacted a rising human and environmental toll. Recent fire climate science research demonstrated clear link between worsening change, mainly though vegetation-drying effect of temperatures shifting precipitation seasonality. New work by Lukovi? et al. (2021) explores observed changes in California's greater detail, finding that rainy season indeed become progressively delayed “sharpness” seasonality increased. These shifts important implications for region's ecology wildfire risk, as they increase degree temporal overlap extremely dry vegetation conditions fire-promoting downslope winds late autumn. Both these are consistent with model projections future, suggesting recent trends may offer an early preview larger to come.

Changes in pest management practice in almond orchards during the rainy season in California, USA
In California, regulatory agencies are concerned about organophosphate (OP) contamination of surface water. OPs originate in part from applications on dormant almond and stone fruit orchards that are washed off during winter rainstorms. Programs conducted by the University of California Statewide Integrated Pest Management Project, University of California Cooperative Extension, and the Biologi...
متن کاملEnhanced future variability during India’s rainy season
[1] The Indian summer monsoon shapes the livelihood of a large share of the world’s population. About 80% of annual precipitation over India occurs during the monsoon season from June through September. Next to its seasonal mean rainfall, the day-to-day variability is crucial for the risk of flooding, national water supply, and agricultural productivity. Here we show that the latest ensemble of...
متن کاملScenarios for future wildfire risk in California: links between changing demography, land use, climate, and wildfire
Over 21,000 future California residential wildfire risk scenarioswere developed on amonthly 1/8° grid, using statistical wildfire models. We explore interactions between two global emissions scenarios, three climate models, six spatially explicit population growth scenarios derived from two growth models, and a range of parameters defining properties’ vulnerability to loss. Scenarios are evalua...
متن کاملStatistical Forecasts of Western Wildfire Season Severity
Strong associations between observed climate anomalies at lags of one season to years in advance and normalized area burned in the western U.S. wildfire season have recently been described using a newly compiled comprehensive gridded western regional fire history (Westerling et al 2001b). Earlier studies of fire scar dendrochronologies and local fire histories have demonstrated that large-scale...
