I wanted to know is there any difference between the temperature on a deck green and open road? If yes, how many degrees Celsius or Fahrenheit right?

Yes, there is a difference, but nobody can say how many degrees, because it depends on many factors such as: how dark is the way the roof – new or old asphalt gray. The temperature difference is what I feel every time my light plane flight on a sunny day. Places such as roads, parking lots, rock (as we have in Norway), and so contrasts with the woods and fields of corn with water. create hot spots and thermal bubbles rising wave my plane. Several years ago, my father, who was also a pilot, but a soldier, his plane crashed taking off from a hot track in the African bush. Only a few feet above the runway, air bag "A" because of the enormous heat from the air as the train was and landed back and belly. The crew was safe, but the plane was doomed. These thermal bubbles or cells are glider pilots to look for used to change and suddenly gain altitude. Glider years also flew with my son and every time we saw seagulls circling knew there was an increase in heat and we join the chain. " The seagulls do not seem to mind having weighed peers.
