Cold air generally has contains less humidity than warm air.
Cold air is more dense and less buoyant than warm air.
air molecules in cold air exert more pressure because they are closer together and collide more often
Does precipitation and storms occur in high pressure sytems Precipitation and storms occur when cold air meets hot air. This can also happen when a cold front moves into a warmer area.
Not really. Warm air usually has a higher volume than cold air, so its density is usually smaller than that of cold air.
This is a cold front. The warm air is forced upwards by the cold air wedging underneath, often forming a narrow line of heavy precipitation.
Cold air is more dense than warm air.
A cold front brings in cold air. The cold air causes warm air to rise quickly. The rising air forms cumulus clouds. There is often heavy precipitation at a cold front.
Warm air holds more moisture than cold air. When the air has reached "saturation point" (ie. it cannot hold any more moisture), it is more likely to cause precipitation as the oversaturated air forms moisture droplets that fall as precipitation. One of the major causes of precipitation is when warm air cools rapidly (for example, when it rises after hitting a mountain front or other landmass). As the warm air cools, it loses its ability to retain moisture and becomes saturated, thus creating precipitation.
Antarctica's lack of humidity and precipitation is caused by the lack of moisture, not necessarily by cold. It is true, however, that cold air holds less moisture due to it having a lower saturation point than warm air.
Cold air is more dense than hot air. This is because gas expands when it is heated.
Hot air has more capacity than cold air (Air expands on heating.
Cold air is more dense and less buoyant than warm air.
Cold Air is more dense than Warm Air.
No. Warm air is capable of holding much more water vapour than cold air.
