Summary:According to the meteorological definition, convection does not contribute directly to fire behavior: convective heat transfer, as related to fire spread, falls under the first definition. [...]pyroconvection is the vertical transport of atmospheric properties driven by or enhanced by fire. Convective downdrafts are a common occurrence during convective precipitation events, and they often lead to the formation of an outflow boundary and a change in surface wind speed, wind direction, and humidity. A cautious understanding of the state of this science and close collaboration between fire managers and meteorologists can help protect firefighters from possible convective influences on fire behavior while the research community works to clarify the influences using improved modeling and observational tools.
