Why does it get so windy during a wildfire?
Wind is created by heat, basically. The sun warming part of the world up and not others creates warmer spots in the atmosphere. That causes warmer air to rise, which means cooler air has to come in to fill in the pressure in those areas.
The Short Answer
Wind is created by heat, basically. The sun warming part of the world up and not others creates warmer spots in the atmosphere. That causes warmer air to rise, which means cooler air has to come in to fill in the pressure in those areas. Because the atmosphere is always trying to be the same everywhere that means wind then goes towards lower pressure areas. This is why traditional weather maps have pressure indications on them. If you're in a low pressure area, everything's coming at you; if you're in a higher pressure area, everything's going away from you, more or less. Fire adds a heck of a lot of extra heat into the equation, so it will pull air into it to keep it fuelled. It's just like a chimney in a house. The whole point of that is to create a big column of warm air, which will rise, and then pull air into the fire to keep it burning. A big enough wildfire will do that on its own.
