Introduction

Atmospheric pressure refers to the pressure of the earth’s atmosphere on its surface by its gravity. The standard is based on the pressure on the sea surface and the unit is represented by hectopascal (HPA). Standard atmospheric pressure is hPa It is defined by weather conditions and elevation. As the elevation increases, the air pressure decreases as the amount of air in the sky decreases. In weather and meteorological observations, it is common to be able to compare the pressure of different places and altitude to the surface pressure.

Applicable Scene

Atmospheric pressure is one of the most important indicators of weather forecasting. The air pressure altimeter which measures altitude based on the pressure is used in the aviation field, and it is indispensable for the safety of navigation. A portable type barometer is also used to detect signs of weather change in mountaineering and outdoor activities. Moreover, in the field of medicine, the effect of the change of the atmospheric pressure on the human body is analyzed in the study of the mountain disease and decompression disease.

Pros: Atmospheric pressure provides a quick and reliable indicator for meteorological observations to reflect the weather changes quickly. The sudden decline in pressure is an important sign to inform the storm or typhoon approach. In addition, since the pressure can be measured globally, it is easy to compare data between different regions. With the advance of the sensor technology, the pressure sensor is installed in the smart phone and the wearable equipment, and it can be utilized for the altitude measurement of the mountain climbing and the weather prediction aid.

Cons: Because atmospheric pressure is complicated by several factors such as temperature, humidity, and altitude, there is a limit alone to explain the weather phenomenon alone. In addition, the change of air pressure also affects human health, and the case which causes the climatic disease and migraine is reported. In addition, the measurement of the barometer is easily influenced by the calibration and the installation environment of the sensor, and there is a problem that the error is easy to occur especially in the moving body and the extreme weather condition.
