How does smoke flow in different environments and what factors influence its movement?

Smoke flows differently in various environments due to factors such as temperature, air pressure, and the presence of obstacles. In a closed space, smoke tends to rise and accumulate near the ceiling due to the natural buoyancy of hot air. In outdoor environments, wind direction and speed can greatly influence the movement of smoke. Other factors, such as the layout of the space and the presence of ventilation systems, can also impact how smoke flows.
