What is the law of temperature distribution?

Temperature distribution law: It decreases from low latitude to high latitude, so the isotherm is generally parallel to latitude. The temperature of the sea and land at the same latitude is different. In summer, the isotherm protrudes in the direction of high latitude on land and in the direction of low latitude on the ocean.

The temperature mentioned in the weather forecast is measured in the open air without direct sunlight (usually measured in a louver). The highest temperature is the highest temperature in a day, generally appearing in14-15; The lowest temperature is the lowest temperature in a day, usually before sunrise.

average temperature

Refers to the arithmetic average of the temperature values observed in a certain period of time. According to the different calculation time, there can be the average temperature of a certain day, month and year.

The average temperature is usually used to represent the temperature of a day, that is, the average temperature. Due to different weather stations, the number of observations per day is also different. According to the regulations of China's meteorological department, the daily average temperature is to average the temperatures measured four times every day at 02: 00, 08: 00, 14: 00 and 20: 00, and the accuracy should be110 degrees.

In addition to the daily average temperature, there are also waiting (5 days), ten-day (10 days), monthly and annual average temperatures. Express the changing characteristics of temperature in different periods. The meteorological department makes observations every six hours at 02: 00, 08: 00, 14: 00, 20: 00 (Beijing time) or 02: 05: 08, 1 14: 00, 20: 00 and 23: 00. For special needs (such as aviation), meteorological observations are even made at intervals of 1 hour and half an hour.
