The atmospheric pressure in our environment changes from time to time. A standard atmospheric pressure is 1013.25 hPa. The main factors that affect the atmospheric pressure of the environment are: altitude, seasons and climate change, etc. Let’s talk about the three main factors of altitude, season, and climate. First, let’s talk about the effects of altitude. Altitude is the factor that has the greatest impact on the atmospheric pressure of the environment. As the altitude increases, the atmospheric pressure decreases significantly. In general areas at an altitude of < 3000 m, the air pressure drops by about 10 hPa for every 100 m of elevation gain. However, due to the differences in temperature, humidity, latitude, landform, and landform in each region, there are many cases where the average annual atmospheric pressure is different while the altitude is the same. Again, let’s talk about the effects of the seasons. Atmospheric pressure changes periodically with the seasons. Atmospheric pressure varies with the seasons and is divided into two types: continental and oceanic. The maximum range of variation is ±8-1OmmHg, i.e., ±10-13.3 hPa. The continental type is on the continent, and the highest value of the air pressure in the year occurs in the winter, and the lowest value occurs in the summer, and the annual difference in air pressure is large. The oceanic type is the ocean, the highest value of the air pressure occurs in the summer, and the lowest value occurs in the winter, because the annual temperature difference on the ocean is smaller than that on the continent, so the annual variation of the ocean pressure is smaller than that of the continental type. The annual difference referred to here is the difference between the average monthly high and the lowest value in a year. Finally, let’s talk about the impact of climate. The change in atmospheric pressure caused by climate change is a non-periodic change in atmospheric pressure caused by the movement and development of a system of high and low atmospheric pressure. The change in air pressure is closely related to atmospheric motion. Over the course of the year, the non-cyclical variation in air pressure generally ranges from 970 to 1040 hPa. In special cases, such as the pressure in the center of Typhoon Borage can be less than 900 hPa; In some parts of China, the maximum pressure can reach more than 1080 hPa. The difference between the maximum and minimum values of sea level pressure can exceed 100 hPa. Over the course of a 24-hour day, the ambient atmospheric pressure also varies, but it is relatively small, around a few hPa. To sum up, the change of atmospheric pressure caused by the season and climate of our sealing pressure products generally affects the range within plus or minus 5kPa, and the influence of geographical location is within 30kPa, which should attract sufficient attention.
