The temperature and the humidity in the air mass stay about?
The temperature and humidity in the air mass remain relatively constant. This indicates that there is no significant change in weather conditions and the air mass is stable.
How does a change in temperature affect relative humidity and specific humidity?
When the temperature of air is cooled or reduced the relative humidity (RH) increases. The moisture content of the air remains the same until the RH rises to the point of 100% saturation and condensation occurs.
What air mass is associated with low relative humidity and high air temperature?
A continental tropical (cT) air mass is associated with low relative humidity and high air temperature. This air mass originates over hot, dry land areas and brings warm, dry conditions when it moves into a region.
What are two possible humidity characteristics of air masses?
Two possible humidity characteristics of air masses are specific humidity, which is the mass of water vapor present in a unit mass of air, and relative humidity, which is the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature.
What are two characteristics used to describe air mass?
Temperature and moisture content are two characteristics used to describe air mass. Temperature indicates whether the air mass is warm or cold, while moisture content refers to whether the air mass is dry or humid.
What happened to the relative humidity of an air mass as water evaporates into the air?
The humidity become higher.
What happened to the relative humidity of an air mass as more water evaporates into the air?
The humidity become higher.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
How do you increase the relative humidity of an air mass?
Add water (vapor) ... evaporation. Lower the temperature of the air mass.
The temperature and the humidity in the air mass stay about?

An air mass forms over Alaska describe what you think the temperature and humidity of this air mass will be?
About 32 degrees ...
What happens to the motion of the object if you change the mass of the object but keep the net force constant?
The relative change in mass will be ofset by a relative change in acceleration:dm/m + da/a=0
When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
If the temperature of an air mass increases by 20oc would the relavative humidity increases or decreases?
If the temperature of an air mass increases by 20°C, its relative humidity would decrease. This is because warmer air can hold more water vapor, so the ratio of water vapor present in the air compared to its capacity will be lower, leading to a decrease in relative humidity.
What air mass is associated with low relative humidity and high air temperature?
A continental tropical (cT) air mass is associated with low relative humidity and high air temperature. This air mass originates over hot, dry land areas and brings warm, dry conditions when it moves into a region.
Why does relative humidity depend on air temperature?
Relative Humidity is the ratio of the mass of vapour present in a certain volume of air to the mass of water vapour required to saturate the same volume of air at the same temperature. Another way of defining relative humidity is related to dew point. I.e relative humidity=s.v.p at dew point over s.v.p at air temperature multiply by 100%. And dew point is dependent upon prevalent atmospheric conditions like TEMPERATURE,wind and the amount of water vapour in the atmosphere.
