Answer 1

Moving air moves heat away from your body about 10x as efficiently as still air. Your body feels heat transfer not temperature, so moving air feels much colder.

This also applies to something like running though in that case you have extra effects of sweat evaporating which takes more heat away from the body. Compounding results as moving air will evaporate your sweat much better than comparable still air.
