It means higher atmospheric pressure, which is generally caused by cool air.
As warm, dry air moves into an area, the barometric pressure typically rises. This is because warm air is generally associated with high-pressure systems, leading to clearer skies and stable weather conditions. A rising barometer indicates that the atmosphere is becoming more stable, which often precedes fair weather.
The result of warm air rising and cool air sinking is convection currents of air, causing wind. Even hurricanes are caused by this phenomenon.
Yes. You would expect the pressure to drop. A low pressure system consists of rising warm air that swirl around a center. Because the air is rising, it lowers the air pressure pressed on the ground. Because of this the pressure-sensing barometer will read that the air pressure is lower. Lower pressure means rain because the warm rising air makes clouds. Expect the pressure to drop as a storm is a low pressure system. Note that cyclones/hurricanes have even lower pressure.
It's known as a convection current not a conduction current :)
The cycle that develops during air rising is called the convection cycle. It involves warm air rising, cooling and condensing to form clouds, followed by precipitation and then the sinking of cool air to complete the cycle.

Cool air moving to take the place of warm air rising is also known as Wind
Cool air moving to take the place of warm rising air is also known as convection. This is how many heating and cooling systems work.
A circular pattern of warm material rising and cool materiel sinking.
Cool air rising through warm air (apex)
The process you are referring to is called convection. Warm air rises because it is less dense than cool air, which causes it to displace the cooler, denser air and sink. This cycle creates a convection current that plays a key role in atmospheric circulation and weather patterns.
As warm, dry air moves into an area, the barometric pressure typically rises. This is because warm air is generally associated with high-pressure systems, leading to clearer skies and stable weather conditions. A rising barometer indicates that the atmosphere is becoming more stable, which often precedes fair weather.
The process of warm rising and cool air sinking is called convection. Convection is the concerted, collective movement of groups or aggregates of molecules within fluids and rheids, either through advection or through diffusion or as a combination of both of them.

The barometer will likely register a drop in air pressure as the moist humid air moves into an area. This drop in pressure is due to the warm moist air being less dense than cool dry air, leading to lower pressure readings on the barometer.
