High greenness is related to low spread rates, and fires spreading in the growing season showed a drastic reduction in spread. High risk related to common fire weather ratings was associated with low ROS.

Collaboration is often needed in complex emergencies like wildfires, but diverse interests can also cause conflict. This study examines how differences tied to organizational roles affected collaboration during 15 US wildfires. Findings highlight when these differences matter most and offer ideas for improving cooperation in complex disaster settings.

Experimental instruments were placed in a burnt area and captured rainfall and extreme hydrologic responses, which is a challenging endeavor with conventional observing networks. Rainfall estimation from a mobile weather radar was shown to be as accurate as rain gauges, with the ability to resolve spatial rainfall fields.

The findings show that two nearby firebrands in tandem arrangement under wind conditions can have a significant cooperative ignition effect on the fuel bed. A semi-empirical correlation for the ignition delay time of the fuel bed based on the energy balance concept is in good agreement with the experimental data.

This research provides a deeper understanding of the activities and hazards associated with severe injuries to wildland firefighters in the United States. Injuries associated with aviation activities result in particularly severe outcomes. Fire complexity was not associated with differences in severity outcomes.

Climate, vegetation type and human activity collectively shape fire regimes in the Nilgiri Biosphere Reserve, Western Ghats, India. Across this landscape, savannas burn more frequently and over larger areas than forests. Overall, fire activity is largely determined by rainfall in dry periods, but by human activity in wet periods.

This article provides a comprehensive review of firebrands’ thermal behaviour, their interaction with natural fuels and structures and their role in spotting. It analyses parameters such as temperature and heat flux, explores key influencing factors, identifies knowledge gaps and proposes future research directions for enhanced wildfire mitigation.
