The cause is weight of the atmosphere.

rain occurs in low atmospheric pressure.
The primary atmospheric factor that affects how a barometer works is air pressure. As air pressure changes, the column of mercury or aneroid capsule in the barometer will move up or down accordingly. Other factors such as temperature and humidity can also indirectly influence barometer readings by affecting air pressure.
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
Hurricanes form from areas of low atmospheric pressure.

The global winds separate into three bands due to a combination of the Earth's rotation, the uneven distribution of heat from the sun, and the Coriolis effect. These forces create the Polar Easterlies, the Prevailing Westerlies, and the Trade Winds.
earthquake No, not earthquake, but changes in atmospheric pressure.
Atmospheric air can be rapidly heated by factors such as strong sunlight, combustion reactions from wildfires or industrial processes, or localized temperature inversions where hot air is trapped near the Earth's surface. This leads to an increase in temperature and can result in the formation of heatwaves or other extreme weather phenomena.
