clouds
how do clouds float
the wind underneath push them up
what's the dew point
it is the point at which clouds can form
which layer does weather normally occur
troposphere (lowest layer)
why does hot air rise
it is less dense
how do cirrus clouds form
from ice
how do clouds form
the sun evaporates water and the vapor rises. once it hits the dew point, it turns into a cloud
explain how precipitation happens
the vapor in the cloud combine with each other till it forms a droplet
radiosonde
a device used to measure the temperature in the atmosphere
what's adiabatic cooling
cooling because the air expands
why are cumulus clouds so poofy
they hit the dew point and spread out because it's not super dense
3 different clouds and their characteristics.
cumulous, puffy, clear weather
cirrus, wispy, hair-like
stratus, spread out, unstable weather
what is lwc
the amount of water in clouds or air
why is the tropopause its own separate section
it is the section where temperature stays the same
what's adiabatic heating
heating because of compression
why are stratus clouds symbols of unstable weather
they are spread around because of wind
orographic clouds
clouds that hover above mountains
how do wind and pressure relate
wind is caused by differences in air pressure
the different layers and what defines them
troposphere, tropopause, stratosphere, mesosphere, thermosphere
the layers are defined by the direction change in temperature
what is the difference between relative and absolute humidity
absolute humidity is the total amount of humidity whereas relative humidity is the percent compared to the total amount of humidity the air can hold
what is the CCN and what does it do
the CCN is the foundation for the water vapor to stick to to form a cloud
street clouds are formed
The wind pushes the vapor up to create clouds but as soon as they cool, they fall back down. The wind above pushes down to heat up the air and it becomes an endless cycle
Depostion
gas turning to a solid without entering the water phase
if the temperature goes up, what happens to the relative and absolute humidity and the dew point
If the temperature goes up, so does the relative. Absolute stays the same unless more water vapor is added and the dew point stays the same
what creates higher and lower relative humidity
Air rises, expands, and cools, creating a higher relative humidity; air cools and sinks, it then compresses, and heats, creating a lower rh
how does the cloud in the bottle experiment work
the match acts as a CCN and the compression heats the air and the decompression creates condensation
