Honey Bee Mystery #2


Tom has visited a lot of mines in the last month but never had one that had warm air coming out of it. It wasn't just warm air inside, it was actually blowing outward.

This can happen in mines with several connected levels where the temp outside the mine varies a lot over the course of a day. During the warm part of the day the cold air is displaced by the hot air outside the mine. The cold air will flow from the lower entrance and war air is pulled in the top portal. Then as air outside the mine cools the warm air in the mine rises and flows out the top portal of the mine. This is what you were likely feeling.
