Folks, if you don't know... don't answer.
Water conducts heat very efficiently. When it is cold outside, the cold gets into your nose. Your body releases a very watery mucous. This mucous appears to be water, but there are salts in it that prevents the water from freezing. This mucuos is a special blend that is unique to winter conditions. It serves 2 purposes. First, by being so watery, it moisturizes the inside of your nose and prevent chapping of your skin inside your nose. Second, it provides a media so that the heat generated by the nose becomes evenly distributed inside the nose and thereby not allowing the sensitive membranes to freeze.
Again, don't answer folks if you don't know.

Baby, it's cold outside - When you're outside on a cold day, the air in your nose is a lot warmer than the air around you. You know how the bathroom gets steamy when you take a shower? Something similar happens in your nose - water drops come together, or condense. Then the drops mix with your mucus and run out your nose.

And now for the correct answer. The entire nasal cavity and respiratory tree are lined with cells that have really tiny hairs on them called cilia. The job of cilia is to move in waves and move things. In humans this system of ciliated cells is called the Mucociliaryblanket. Each day we produce liters of mucus that is moved down the throat by the action of cilia, and mucus is moved up the trachea away from the lungs and down the throat. The reason for this is to moisten the air we breathe, and also to keep foreign particles out of the lungs. Now these cilia work great when it is warm, but when you go outside they get sluggish and stop moving. Now all that normal mucus is stagnant and does not move and that is why is accumulates and you nose runs.

I do not know for sure,but I can take a guess. I would say, because when it is cold and windy bacteria gets into your nose, and it is trying to keep bacteria away from your body by running. Or It is keeping your body from getting a cold or keeping it warm. I am not exactly sure, but that is my guess.

Runny noses in cold weather are the result of your body's metabolism speeding up to help you stay warm. Your endocrine and exocrine system also speed-up, and this gets your juices flowing, so to speak. Also, the viscosity, or the thickness, of your snot--I mean mucus, LOL--is then decreased from your increased body heat and metabolism, so it runs like water.

because (I don't know this for sure just guessing) when it is cold bacteria is all around and ur nose is trying to fight off the bacteria therefor causing it to run.
