Warmer air is less dense than colder air (think PV = nRT. If T goes up V goes up too). As a result, the warmer air rises due to buoyancy effects. Since air is not a very good conductor of heat, the temperature gradient persists unless the air is forced to mix. This is a reason why running a ceiling fan in the winter can help get a room warmer - by mixing the warmer air at the top of the room with the cooler air lower down.

What is the temperature when a thunderstorm occurs?
Thunderstorms do not form at any particular temperature, but generally speaking the warmer and moister the air is at and near ground level the more likely it is that a thunderstorm will form. Thunderstorms form when lifted air parcels end up warmer than the air surrounding them.
Which holds more moisture warmer air or colder air?
The air that holds the most moisture in their air hole is warmer.
What is the purpose of a ceiling fan?
A ceiling fan provides air circulation which can make the air immediately around your body cooler (because if the air is stagnant the heat from your body will make you feel warmer than the actual room temperature). It is important to note that a ceiling fan actually contributes heat to a room, so if no one is going to be present to enjoy its effects, you might as well turn it off.
What occurs when warmer air lies above polar air?
A jet stream occurs when warmer air lies above polar air.
Does a warm front have warmer air move against cooler air?
Exactly. the colder air is lifted up over the wedge of warmer air at an angle.
Near the ceiling of a room the air is warmer the warm air rises because of?
Conduction
Why is the air temperature near the ceiling of a room tends to be warmer than near th floor?
The hot air is lighter than the cool air so it floats to the ceiling.:)
Is cooler or warmer near the ceiling?
wamer
Why should air-conditioning installation be near the ceiling of a room instead of the floor?
Because cooler air, being more dense, will tend to gravitate downwards as it replaces the warmer air.
Why the air temperature near the ceiling of the room tends to be warmer than near the floor?
Because warm air rises over cool air. Warm air is less dense than cool air, and it's lifted by buoyancy and floats on the more dense cool air.
Why does the temperature near the ceiling tend to be warmer than near the floor?
Hot air rises cold air falls, a example of this is hot-air balloons, hot-air balloons use a fire to heat up the air inside it so it will rise and they also have a latch to relase some of the hot air so that the ballon will desend.
Why are heaters fitted near the floor and air conditioners near the ceiling of a room?
Cold air falls...warm air rises
Why are air conditioning units placed near the ceiling?
help me
Why is air near the ceiling the warmest?
heat rtises, cold sinks.
In winter where should the heater be placed in the room near the floor or near the ceiling?
Heat naturally moves to colder air. Place the heater on the floor and it will rise to the ceiling, as it is lighter than the cold air.
Why are exhaust fans in kitchen fixed near the ceiling?
Cooking odors are usually found in the warmer air around stoves and ovens. This air typically rises to the ceiling. Most exhaust fans are either directly above the stove or in the ceiling above the cooking surfaces. Exhaust fans are more efficient at removing cooking odors than recirculating fans (which use charcoal filters).
Is there warmer air in a convection current?
A convection current in air will have warmer air near to the heat source and this will rise. Then it gradually loses heat to the surroundings and sinks again, so there is warmer air in parts of the current and cooler air in other parts.
