Temperature and air pressure

Temperature refers to the level of heat or cold that appears in various masses of matter and can be expressed as a definite numerical value. The temperature of the Earth's surface is related to the absorption and emission of heat energy from solar radiation. For example, solar radiation begins around 6:00 AM. The amount of radiation or heat energy received by the Earth gradually increases over time until 12:00 PM, which is when the Earth receives the most radiation from the Sun. After that, the amount of radiation gradually decreases. When the Earth receives radiation from the Sun, it emits radiation into the atmosphere in the form of long waves, causing the lower layers of air to heat up. Most of the heat received by the air comes from the Earth's radiation. However, the time of the daily maximum temperature is not the same everywhere; it usually occurs between 2:00 PM and 4:00 PM. This is because during this period, the Earth is still receiving radiation from the Sun, although in decreasing amounts. It can be said that the Earth receives more heat energy from the Sun than it loses. Therefore, after approximately 2:00 PM, the Earth loses heat energy through the release of heat or radiation from the Earth's surface. Consequently, the air temperature begins to decrease until it reaches its minimum at 6:00 AM. Atmospheric Pressure is the weight of the air pressing down on a specific area. Atmospheric pressure can be measured using an instrument called a "Barometer." The unit of measurement is millibars or pounds per square inch. Normally, humans can live without feeling the pressure from atmospheric pressure because the human body contains air as a component. The internal air pressure in the human body has an outward force equal to the external force, so we do not feel suffocated. At the same time, wh
