A downdraft.
Cool dense air descending from the back of a storm is known as a downdraft. Downdrafts are associated with sinking air motion that can bring strong winds and rapidly changing weather conditions.
Differences in density can cause air masses to rise or sink. When warm, less dense air rises and cools, its relative humidity may reach 100%, causing water vapor to condense into liquid water droplets, forming clouds. Conversely, when cool, denser air descends and warms, it can inhibit cloud formation as it becomes more capable of holding moisture.
A cool region of air underneath clouds will have higher density compared to a region with no cloud cover. This is because the cool air is denser and heavier, providing greater atmospheric pressure. The presence of clouds can trap cool air near the surface, contributing to its higher density.
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.

The cool dense air that descends from the back of a storm is known as a downburst. This phenomenon occurs when precipitation from a storm falls and drags cooler air down with it, which then spreads out horizontally upon reaching the ground. Downbursts can lead to strong, damaging winds and are often associated with severe thunderstorms. They can pose significant hazards to aviation and can cause damage to structures and vegetation.
The cool dense air that descends from the back of a storm is known as a "downburst." This phenomenon occurs when rain-cooled air becomes heavier than the surrounding air, causing it to rapidly sink and spread out upon reaching the ground. Downbursts can lead to strong, gusty winds and can be dangerous for aviation and outdoor activities. They are often associated with severe thunderstorms and can create conditions for microbursts, which are localized and intense.

A star is formed out of cloud of cool, dense molecular gas. In order for it to become a star, the cloud needs to collapse and increase in density.
well if it is less dense or cool dense than a tornado forms in a wet cool place.
The cool, dense, and heavy water droplets in the cloud eventually combine to form larger droplets or ice crystals. When these droplets or crystals become too heavy to be supported by the air currents in the cloud, they fall to the ground as precipitation, such as rain or snow.
Most tornadoes form during supercell thunderstorms as a result of the mesocyclone (organized rotation in the atmosphere) lowering into and below the cloud base. As the mesocyclone descends, there is a convergence between the cool air of the downdraft and the warm air of the updraft. This causes the rotating wall cloud to form. As the mesocyclone descends even further, it becomes the funnel cloud that is visible to the eye. The 2006 Saroma tornado in northern Japan was the countryÕs deadliest ever recorded.
When cool air descends from mountain peaks, it often leads to the formation of a temperature inversion, where the cooler air traps warmer air below. This can create a stable atmosphere that inhibits cloud formation and precipitation. Additionally, the descending air can warm adiabatically, leading to the development of clear skies and dry conditions in the valleys below, a phenomenon known as a rain shadow effect.

In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
