Can the household pointer barometer reflect the air pressure changes in different seasons?
The types of barometer are mercury barometer and aneroid barometer. Due to the transmission device of the empty box barometer, the measurement result of air pressure is not very accurate. The barometer can only measure the current air pressure value, but can't reflect the air pressure change in a day, let alone the air pressure change in different seasons. Because for the same area, the air pressure on the ground will be different at different times of the day, which is the daily variation of air pressure. In a day, the atmospheric pressure on the earth's surface has a maximum and a minimum. The highest value appears at 9 ~ 10. The lowest value appears in 15 ~ 16. Generally speaking, the air pressure in sunny days is higher than that in cloudy days, and the air pressure in winter is higher than that in summer. If we want to reflect the pressure change in different seasons, we should record the daily average pressure value of each month and draw a line chart of the pressure change, so as to reflect the pressure change in different seasons.
