Daily variation law of temperature

The law of this change is low → high → low.

There is a maximum temperature and a minimum temperature in a day, and the difference between them is the daily temperature difference. The highest temperature appears in 14 ~ 15, and the lowest temperature appears around sunrise.

Due to the influence of season and weather, the occurrence time is ahead or behind. The highest temperature in summer often occurs in14 ~15; Winter is 13 to 14.

Because the sunrise time at different latitudes is different, the occurrence time of the lowest temperature will also vary with latitude.
