Isn't is rather self explanatory?
No- it just means that it was left open in the warm air.
A warm air mass rises over a cold air mass at a warm front because warm air is less dense than cold air. This results in the warm air mass being forced to rise and cool, leading to the formation of clouds and precipitation at the boundary of the two air masses.
Cold air is drier than warm air because cold air has a lower capacity to hold moisture compared to warm air. This means that when cold air is heated, its relative humidity decreases, making it feel drier.
it means hot or warm.
A cold front means the leading of a cold atmospheric air mas moving against and taking over a warm air mass, creating a cold front. The cold air replaces the warm air due to the cold air having a higher density then the warm air.
Most likely, yes. Falling pressure means that warm air is rising and warm air can hold more water vapor than cooler air. When warm wet air rises, it cools and this often results in cloud formation and possibly precipitation.
it means when a front is been moved up one then it becomes a warm front if it is moved down one it means a cold front
If a colder air mass actively displaces a warmer air mass at the surface, then it is called as a cold front.That means cold fronts bring cold air into warm areas.In such a condition,the warm air is forced to move upwards resulting in the formation of a low pressure area or depression.If the warmer air mass flows actively upwards(as it is lighter) over the cold mass below, then it is called as a warm front.That means warm fronts bring warm air into cold areas.In such a condition ,the warm air rises gradually over the cold air resulting in the formation of cloud and rain.
The cold air pushes under the warm air.
I pushes the warm air upwards.
warm air
a warm air mass is a large body of air that is extremely warm
