Ionosphere
higher durning the day and lower during the night
If you mean short waves, the answer is that the lower layer of the ionosphere (D layer) dissapears at night so short wave signals then bounce off a higher layer (F1 or F2) of the ionosphere and can travel further.
Does the lower the AM radio frequency number goes require night power to be lower or higher?
yes it is. but the earth moves away from the sun at night and it moves out of its light and into darkness.
Because in day time the ionisation is less in the D layer of the Sky. So it absorbs the medium waves because of its lower frequencies. In night time the D layer vanishes and the Medium waves travel towards the F layer and reflected back to the earth from a long distance. That's why Medium waves are clearly heard in night times from a long distance.
At night, wind near an ocean shoreline typically moves from the land to the ocean, a phenomenon known as a land breeze. This occurs because the land cools more quickly than the water, creating higher pressure over the cooler land and lower pressure over the warmer water. As a result, the cooler, denser air moves out towards the ocean, creating a breeze that flows from the land to the sea.

Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
Because the lights that cause them are relatively low. Lower lights ==> longer shadows. Higher lights ==> shorter shadows.
The average night stay at Breckenridge hotels is about $100 dollars. The price could be higher or lower depending on the season. You can find discounts and coupons if you do research.
