What are the daily and annual variation characteristics and geographical distribution characteristics of temperature?

The daily variation of temperature is: the temperature is the highest in the afternoon 14, and the lowest before and after sunrise in the morning, showing a wavy distribution.

The annual variation is characterized by the small annual variation of temperature in low latitudes, but the large annual variation of temperature in temperate cold regions. The land temperature in the northern hemisphere is the highest in July, and the lowest in June is 65438+ 10, but the opposite is true in the southern hemisphere.

Distribution characteristics are influenced by latitude, land and sea distribution (underlying surface), topography (high temperature in basin and low temperature in mountain area), ocean current (cold current cooling and dehumidification, warm current warming and humidification), human activities (urban heat island effect) and other special circumstances!
