Which factor does NOT influence fire pattern generation?

Fire pattern generation is influenced by multiple factors that impact the behavior and spread of fire. Among these factors, a fire plume refers to the rising column of hot gases produced during combustion, which can shape the fire's path and the way it distributes heat. Ventilation plays a crucial role as well, since it can either enhance or inhibit the fire's intensity and growth depending on the availability of oxygen and how air flows through the environment.

Fire suppression techniques directly alter the dynamics of a fire by applying water or other agents to cool and extinguish the flames, which can also affect how patterns form in the aftermath of a fire incident.

In contrast, surrounding temperature, while it can have an effect on the overall fire environment and potentially influence the rate of combustion, does not directly create or define a fire pattern. Fire patterns are primarily determined by the interaction of fire phenomena, active fire management strategies, and the materials involved in combustion, rather than just the ambient temperature alone. Therefore, surrounding temperature is the factor that does not influence fire pattern generation in the context presented.
