warm and cold winds

[David King]

Can someone help?

I got myself in a bit of a confuddle yesterday trying to answer a  
pupils question.

"Sir, why, if temperature is to do with Kinetic Energy is wind cold?"

I started on evaporation from the skin etc and the idea of us  
'feeling' cold, when he asked

"Why do we have warm winds? What's the difference?"

I started to answer then stopped. What makes air particles travelling  
at whatever kph warm or cold?

Cheers
