Key message We investigated relationships between the spatial patterns of burn severity in
Chinese boreal forests and weather parameters. Patch size, shape and arrangement
differed between high-severity and low/moderate-severity patches. Wind speed and relative
humidity were dominant weather parameters of spatial variation in burn severity. Patch size
negatively correlated with relative humidity; patch complexity and aggregation positively
correlated with wind speed. Context Spatial patterns of burn severity strongly control post …

Context: Spatial patterns of burn severity strongly control post-fire succession and numerous
ecological processes in fire-prone boreal forests. Burn-severity patterns are strongly tied to
weather conditions. Understanding how weather influences spatial patterns of burn severity
is critical for predicting burn severity and fire management strategies. Aims: We investigated
relationships between spatial patterns of burn severity and weather variables in the Chinese
boreal forests. Methods: Using satellite imagery, we mapped burn severity for 22 fires that …
