water
only liquid found on Earth’s surface in Large Quantities, is readily converted from one state of matter to another, it‘s solid phase, ice, is less dense than liquid water, has a high heat capacity
Why is water unique
Temperature changes that result from changes in pressure rather than changes in heat energy
What is Adiabatic temperature changes?
Humidity is the general term used to describe the amount of water vapor in the air.
What is humidity?
The warmest part of the day
When does cloud formation often take place?
Warm air can hold more water vapor than cold air, so the relative humidity changes as the temperature changes
How does temperature affect relative humidity?
The energy that does not produce a temperature change
What is latent heat
The rate of cooling or heating applies to only unsaturated air
What is dry Adiabatic rate
Absolute humidity, mixing ratio, vapor pressure, relative humidity and dew point
How is humidity expressed?
LCL (lifting condensation level)
What is it called when clouds started to form?
High relative humidity can cause discomfort and problems like mold growth
What problems can high relative humidity cause?
Melting, evaporation, sublimation
The slower rate of cooling
What is wet Adiabatic rate?
The mass of water vapor in a given volume of air
What is absolute humidity?
The first way is when moisture builds up until it reaches the maximum amount of volume it can hold. The other method reduces the temperature of the moisture filled air, which lowers the amount of moisture it can contain.
What are the two ways to form clouds?
When the dew-point temperature is reaches, any additional moisture in the air will condense into liquid form, causing dew of frost to form
What happens when the dew-point temperature is reached?
Which processes release energy?
There is no answer
A parcel of saturated air with a temperature of 10 degrees Celsius descends 1000 feet towards the surface of the Earth. What is it's new temperature?
The mixing ratio is the mass of water vapor in a unit of air compared to the remaining mass of dry air
What is the mixing ratio?
Clouds are formed when air contains as much water vapor as it can hold.
What is saturation point?
It helps in predicting weather conditions because it is an important factor in determining the likelihood of precipitation and fog
How does dew-point temperature help in predicting weather conditions?
When water absorb heat, the latent heat breaks hydrogen bonds; when water releases heat, there is not a lot energy left which allows hydrogen bonds stay.
How are hydrogen bonds related to the changes of state?
Mid-troposhere vertical wind helps meteorologists determine the pressure changes in Adiabatic processes and change in temperature, humidity and dew point.
What role does mid-tropospheric vertical wind play in adiabatic processes?
Vapor pressure is defined as that part of the total atmospheric pressure attributable to its water vapor content
What is vapor pressure?
Convergence, convection, frontal lifting, physical lifting
What are the four processes to ascent and expand?
Understanding relative humidity and dewpoint temperature is important for meteorologist because it helps them predict weather conditions and prepare for severe weather events
Why is understanding relative humidity and dew-point temperature important for meteorologists?
