Abstract. Holdover fires are usually associated with lightning-ignited wildfires (LIWs), which can experience a smoldering phase or go undetected for several hours, days even weeks before being reported. Since the existence and duration of combustion in LIWs is unknown, holdover time conventionally defined as between lightning event that ignited fire detected. Therefore, all have an time, may range from few minutes to days. However, we lack comprehensive understanding times. Here, introduce...
South America has experienced severe compound drought-heatwaves (CDHW), exacerbating fires. Recently, the unprecedented Pantanal 2020 fire season (P20F), burning a third of biome, resulted in well-reported local impacts on ecosystem, economy, and health. Nevertheless, long-range ripple effects this event remain unknown. We investigated P20F-related cascading hazards, integrating models, observational satellite-based data. smoke elevated PM2.5 levels SA's most populated area, exceeding WHO...
Human-induced climate changes have increased the frequency of simultaneous hot–dry events. In 2020, occurrence compound droughts and heat waves (CDHW) conditions in Pantanal (the largest continuous tropical wetland located central-western Brazil) exacerbated fire risk, leading to unusual amounts burned area (BA). Despite well-documented local impacts on ecosystem economy, besides regional effects that included black sky episodes South Southeastern Brazil, number studies...
Fire databases typically contain information regarding the location, timing, and duration of fire occurrences, as well cause (natural or human-induced). These allow for analysis understanding circumstances surrounding ignition propagation wildfires, being highly relevant when addressing suppression management plans, improvement prevention policies. In Portugal, Mediterranean country with highest burned area over last five decades, a large number fires in official database have unknown...
Abstract Under current global warming, South America (SA) has been experiencing severe compound drought-heatwave (CDHW) conditions, which, in turn, exacerbate fire risk. A recent showcase is the unprecedented Pantanal 2020 season (P20F), when one-third of biome was burned, with reported local impacts on ecosystem, public health, and economy. Nevertheless, extent to which this event led long-range ripple effects remains unknown. Here, we explored a cascade chain hazards along continent...
