Comment on Why is there steam coming out of the streets in New York

There’s a lot of things under the streets of New York, many of them cause heat. In order to cool them off the heat is vented outside and the warm moist air meets with the cool dry air and condensates into droplets that we see as steam. Same affect as breathing out on a cold day, you’re not creating steam but it looks that way because the warm moist air from your breath is condensing in the cool dry air.
