大约在下午5时至6时左右,干燃料的火灾风险峰值为布什,这为改进复杂地形的火灾预测提供了新工具。
Bushfire risk peaks in dry fuel around 5–6 p.m., prompting new tools for better fire forecasts in complex terrain.
澳大利亚国立大学研究人员在空气后大约两小时,通常是下午5时至6时左右,发现林火燃料峰值为干燥,将高火灾风险扩大到晚上,特别是在日光节省期间。
Australian National University researchers found bushfire fuel peaks in dryness about two hours after the air, typically around 5–6 p.m., extending high fire risk into the evening, especially during daylight saving.
利用实时传感器和当地数据,该研究显示,卫星和天气预报在诸如沟渠和密集植被等复杂地形中不那么准确,那里的湿度在很短的距离内各不相同。
Using real-time sensors and local data, the study shows satellite and weather forecasts are less accurate in complex terrain like gullies and dense vegetation, where moisture varies over short distances.
该小组正在开发各种工具,将卫星数据、地形图和植被图结合起来,以30米分辨率估计燃料湿度,改进火灾风险预测和更安全的处方燃烧。
The team is developing tools combining satellite data, topography, and vegetation maps to estimate fuel moisture at 30-meter resolution, improving fire risk forecasts and safer prescribed burning.
长期目标包括改进不同燃料类型的模型,以便更好地预测澳大利亚南部和东南部的火灾行为。
Long-term goals include refining models for different fuel types to better predict fire behavior in southern and southeastern Australia.
