Can anyone provide a recent link to a wind chill factor for cycling.

Cheers

    If you put an ice cube outside when the air is 2 degrees C will it melt more quickly or more slowly if it is windy than still?

    A body at rest relative to the air around it has a slower heat exchange with the surrounding air than one with relative airflow (boy or air or both moving).

    The human body is at circa 37C, it heats the air around it (well in the UK where the temperature rarely gets near 37C), if that air stays in place heat loss to it is slower than if its being 'changed' by airflow.

    Quicker. The ice cube is cooler than the air around it. The moving air replaces the air cooled by the ice cube with more warm air. Obviously the reverse would be true if the air was colder than the ice cube.

    The only confounding factor in the ice cube example is the melted water. The wind moving over the ice cube will evaporate the water (assuming it's not already saturated) and that will provide some cooling effect.

    BTW - my Gore Biking dealer had windchill tables (those "calculator" discs) in the shop - presumably to help sell Windstopper clothing. I had one somewhere but can't find it nor can I find it on the Windstopper website or Googling it.

    Neutral Skin Temperature is 33 C.
