Answer 1

Answer:

Hello! The most likely factor of this cooling is radiational cooling of the atmosphere. This happens when energy from Earth's surface and the air above it radiates into the upper atmosphere, causing cooling at and in the air near the surface. The longer the night is, the more intense this effect is, so that's one reason the temperature will drop right before sunrise (as the night goes on).
