Why does the air blow warm when I am come to a idle?

When you come to a stop, the airflow around you decreases, and the warm air that has been heated by the sun or your body temperature becomes more noticeable. Additionally, if you’re in a vehicle, the air conditioning may no longer be circulating cool air, causing the ambient temperature to feel warmer. This effect can also be amplified if you’re in a location with limited airflow or in direct sunlight.
