Ceiling fans for climate control?

[Kiwassa]

Hi,
I've been living in my yurt in the Adirondacks for 9 months now. We experience pretty extreme temperature swings here. On a hot day the yurt interior can sometimes reach temperatures greater than 100 degrees, even with the

dome

cracked. Last summer, the nights were downright chilly, even with the occasional fire in the woodstove.
Has anyone had any success controlling the climate of the yurt using a ceiling fan? My thought is I can better ventilate the yurt during the day and then reverse the circulation of the fan at night to force warm air downward. My thought was to hang the fan directly below the

dome

for better convection inside the yurt.

Last July and August I did not spend the day inside the yurt if I could avoid it because of the extreme heat. Every night I found myself bundling up, because the temperature inside would drop to 40 degrees. I'd rather not keep my

insulation

up all summer so I'm hoping the fan will help provide a little more regulation.

Any idea if it's worth the effort?
