What is weather? The state of the atmosphere at a
specific time and a specific place

Humidity The amount of water vapor present in
the air

Relative Humidity the measure of the amount of water
vapor present in the air compared to the amount needed for saturation at a specific temperature

Dew point The temperature at which air is
saturated and condensation forms is the dew pointHumidity vs dew point

what is fog?When air is cooled to its dew point near
the ground, a stratus cloud is formed that we call fog

CloudsThey are classified by shape and height
stratus cirrus cumulus
add nimbus to any name means that the cloud has rain or snow attached to it

Cumulus masses of puffy white They tower at great heights and can be
associate with thunderstorms

Cirrus appear fibrous or curly They are high and thin white and feathery made of ice crystals because of their
height

Stratus form at very low altitudes associated with fair weather, rain , or
even snow
Clouds are awesome to watch! Each one is unique
watch

Precipitation Water falling from clouds
snow ice rain hail sleet
The air temperature determines whether water forms rain, snow, sleet or hail
