Generally speaking I suppose temperature rises as long as the sun is up and then it continues to fall until sunrise the next day. I have once noticed temperature rise temporarily during night (In my institute where I study, a temperature board out side Department of Hydrology displays the temperature). Is there an error in the data or is it possible for temperature to rise during the night? Is it possible naturally?
I am not sure if this question belongs here in the physics section so sorry if I am transgressing.
