Need help explaining chimney draft

I am not getting it explained to someone so they can understand. I think it’s a case of them over thinking what I’m trying to tell them.

Can someone help me explain why draft is stronger in cold weather and less in warm. Maybe having it written and readable will help an analytical mind grasp what’s happening and why.


Thanks hoarders

Draft is simply a column of lighter warm air rising into the cooler atmosphere...the greater the temperature difference, the faster it rises

 

All because warm air is "lighter" than cool air or cool air is more dense than warm air.

 

They read this and asked, “so it’s like a hot air balloon rising faster on a cold morning with less burner?". Yes, exactly.

Thank you.

Glad they got it understood, thought we might have to get the crayons out

 

That’s how things usually work with them. Some people are to book smart for their own good. The best friends you could ask for but absolutely lacking common sense and a grasp on reality.
