how can air temperature increse at midnight?


got curious just today. at 9PM it was 2°c but now at 0AM its 6°c and will keep rising way before sunrise. how can this happen without sun and absolutely no wind whatsoever. i guess its also possible temperature to drop when there’s sun around and this makes me even more scared

The sun is only one source of temperature in weather. Another, often bigger part is weather systems; large pieces of air that travel across the land and have similar temperature, pressure, and humidity. This is what people are talking about when they talk about a “low pressure system” or “high pressure system” or even “tropical storm”.

Systems still move when the sun is down, so if a warm weather system arrives after midnight it can cause the increase in temperature you are seeing.

ELI5: Who uses “0AM” as a time designation? Never heard it before.
