Is it high pressure or low pressure when the weather is gloomy and sultry?
Usually, air pressure is closely related to the weather. Generally speaking, areas with high ground pressure are often sunny, and areas with low ground pressure are often rainy. Generally high pressure and low pressure are relative, not the absolute value of atmospheric pressure.
For example, the air pressure in a certain area is higher than the surrounding air pressure, which is called high pressure area. The air pressure in a certain place is lower than the surrounding area, which is called low pressure area. On the same horizontal plane, if the pressure distribution is uneven, air will flow from the high pressure area to the low pressure area. Therefore, the high-pressure central area is not conducive to the formation of clouds and rain, and it is often sunny.
