The oxygen content of cold and warm air is exactly the same...roughly 21%. However, cold air is more dense, so a given volume of cold air will contain more oxygen molecules than warm air. The oxygen content doesn't change with temperature...only the density.

Thank you Dallas Rains! But we are talking about a smaller amount of cold air witch does in fact contain more oxygen than the same volume of warm air. I learned all about cumulus and rain in grade school. Your lessons on rain are contradicted by the last two lines in your post Tex. Witch one do you wanna talk about?
