Urban areas across the UK are becoming increasingly susceptible to wildfires, particularly due to a phenomenon called 'firewaves.' This term represents the occurrence of multiple wildfires driven by prolonged hot and dry weather. Recent incidents in London and Edinburgh illustrate the heightened vulnerability of these cities to fire outbreaks, previously seen primarily in rural regions. Researchers at Imperial College London have devised methods to predict wildfire conditions, emphasizing the importance of moisture levels and atmospheric extraction factors, as dry vegetation significantly raises fire risk.
The phenomenon termed 'firewaves' refers to multiple urban wildfires ignited by extended periods of hot, dry weather, posing a significant risk to cities.
Researchers found that after ten consecutive days of very dry weather, the likelihood of simultaneous wildfire outbreaks increases significantly due to desiccated vegetation.
The vapour pressure deficit is a crucial factor in predicting wildfire risks; higher levels indicate drier vegetation that is more susceptible to ignition.
London Fire Brigade works with researchers to predict potential wildfire hazards, emphasizing the need for cooperation in tackling this growing threat to urban areas.
