The Short Answer
When you breathe in through your nose you're filtering the air before it goes into your lungs, and pulling it through a smaller opening, forcing you to inhale slower taking deeper breaths. You exhale through your mouth because it's a bigger opening and you want to get the 'bad air' out as fast as you can. Your nose also helps regulate the temperature of the air you're breathing. When it goes in your mouth it goes very quickly into your lungs, and if it's too cold it can be jarring to your lungs. I'd guess, when it's way too hot out, like today, it also serves to cool it down a bit.
