What are the laws of temperature change?

1, the variation law of temperature in a year:

Northern Hemisphere: The highest temperature on land is July, and the lowest temperature is 65438+ 10 month; The highest temperature in the ocean is August and the lowest temperature is February.

Southern Hemisphere: the highest temperature on land 1 month and the lowest temperature in July; The highest temperature in the ocean is February and the lowest temperature is August.

2, the temperature change in a day:

The temperature change is mainly affected by sunshine.

When the sun is big, the temperature rises quickly after 9 o'clock; If it is cloudy or cloudy, the temperature rises slowly, but generally it reaches the highest at around noon 13: 00, then it drops slowly, reaches the lowest at around 5 or 6 am, and then starts to rise slowly.

3. What's the temperature change around the world?

From the equator to the poles, the temperature gradually decreases, because the solar altitude angle in the polar regions is relatively small all year round, so less solar radiation energy is obtained.
