Convection at it's coldest

Convection can be cold, yes cold. It is obvious because of a cool gust of wind or a snowy breeze can make you cold. That cool gust of wind or snowy breeze is cooler than your face, so when it blows across your face, heat from your face will transfer to the wind and will leave your face cold.
