What are some properties of air in chemistry

In short: the effect of atmospheric pressure on weather conditions Rising air creates negative pressure, falling air creates high pressure. At high pressures, the descending air suppresses the development of time. High air pressure ensures clear skies, dry and stable weather. In an area of ​​low pressure, the wind quickly spreads inwards and upwards. As a result, the air rises and the cloudiness cools and precipitation forms.
