The geographical temperature in high school in annual range is higher than that in low latitude, and the daily range is higher than that in high latitude. Explain.

The difference between the highest monthly average temperature and the lowest monthly average temperature in a year is called temperature annual range.

Generally speaking, in temperate regions, due to the great difference in sunshine time between two seasons in Xia Dong, the annual temperature difference is large.

Tropical areas are very hot all year round, so the annual change is very small.

Diurnal range is the difference between the highest temperature and the lowest temperature in a day.

Generally speaking, the subtropical zone is the smallest, and it gradually increases to high latitudes: the average value in high latitudes is 12℃, in middle latitudes it is 7-9℃, and in low latitudes it is 3-4℃. In mid-latitude areas, summer is larger than winter, while in low-latitude and high-latitude areas, it does not change much with the seasons. Generally, the daily range in summer is greater than that in winter, but in the middle and high latitudes, the maximum daily range in a year appears in spring. Because in summer, although the height angle of the sun is large, the sunshine time is long and the temperature is high during the day, the daily temperature difference in summer is not as large as that in spring because of the short day, short cooling time and high temperature at night in the middle and high latitudes. As far as land and sea are concerned, the ocean is smaller than the inland: generally, the ocean is only 1-2℃, and the inland can reach 15℃ or even 25-30℃. As far as topography is concerned, valleys are larger than peaks, and depressions are larger than highlands. As far as weather conditions are concerned, cloudy days are smaller than sunny days.
