Subject: warm and cold winds

 

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
