Thermal Tunnel

Unread postby WVFrid » Mon Nov 02, 2015 1:18 am

Sorry if this has been covered before. The question just popped into my head yesterday. If its cool and overcast all day, will there still be a thermal effect created and a thermal tunnel? I try and watch when the sun hits the ground floor for it, buts thats not possible on cloudy days.

Yes thermal effects will still happen under cloudy overcast days.

Yea, just not as strong generally. A good way to tell is the temp. difference from hi-lo. Big temp change means strong thermals.

Also that wind tunnel on the leeward side will happen even without thermals when there is a decent wind speed, just by the turbulence of the wind coming over the hilltop. But thermals kind of 'reinforce' the vacuum effect when they are rising.
