About Barometer
On a barometer, high pressure and low pressure are relative and there is no clear demarcation. However, we can take 1000hPa as the boundary, with low pressure area to the left and high pressure area to the right. Using an adjustable pointer on a barometer lens, you can simply mark the current atmospheric pressure and watch it change. You can read it at least once a day and record how often the pressure changes. Multiple readings a day will give you an accurate weather forecast. Although there are many practical factors that affect weather, such as location, temperature, humidity, wind direction and season, observing changes in atmospheric pressure allows you to make weather forecasts.
Temperature Humidity and Atmospheric Pressure
Temperature and people's life is inseparable, people are always seeking or creating the best temperature in all areas of life. 8 ~ 15℃, is the best temperature of grain storage, this temperature can prevent food insects. 35 ~ 38℃ is the best temperature for bathing water, because this temperature is similar to body temperature. So, what's the best temperature in a room? 18 ~ 20℃.
Air humidity refers to the degree of air humidity, can be expressed by relative humidity. Relative humidity refers to the actual density of water vapor contained in the air and the percentage of saturated water vapor density at the same temperature. According to the scientific test, the relative humidity of the general li
