Thanks - BTW I was confused because I'd call that avoiding "wind-chill", or even avoiding "advection cooling" (from a techincal fluid dynamics perspective)... "convection cooling" makes me think of heat loss by warmer air rising, not due to lateral flow. But that's the ordinary meaning - technically, convection and advection are synonyms, so you're quite right.
