Unit 2 Lesson 1
Influences on Weather
Objectives:
Explore various elements of weather
Cause and effect relationships that work together to influence
weather
Study how weather is influenced by interactions involving the
atmosphere, temperature, precipitation, air pressure and wind

Weather is the present state of the
atmosphere. Weather is short term
The interaction of air, water, and the sun
causes weather. What factors determine
what the weather is going to be like?
1. Air Temperature
• Air is made up of randomly moving
molecules
• Temperature is a measure of the average
amount of motion by the molecules
• High motion = High Temperature
• Low motion = Low Temperature
2. Humidity
is the amount of water vapor in the air.
Relative humidity refers to the
amount of water vapor the air is
holding compared to the amount it
can hold at a temperature.
***The warmer the temperature, the
more water the air can hold.***
The air can only hold a certain amount of
water vapor, so when the air is fully saturated
condensation will occur. This is called the
dew point. The dew point will change with the
amount of moisture in the air.
3.
Clouds form when water vapor in
the air condenses around a particle
of dust or salt. These particles are
know as nuclei. When millions of
these droplets collect, a cloud
forms.
Clouds are classified into three
main types based on their
shape.
Stratus clouds form in flat layers. They
look like smooth even sheets at low
altitudes. They can be seen in fair
weather, but they can also thicken and
bring drizzle.
Stratus clouds near the ground are called
fog.
Cumulus clouds look
like fluffy, rounded
piles of cotton. They
are usually associated
with fair weather when
they are small. Larger
ones are called
nimbus or
cumulonimbus and
are associated with
thunderstorms.
Cirrus clouds are found at high altitudes
and because of their height, are made of
ice crystals. They are thin and feathery.
They usually indicate that the weather is
changing.
Do Now
1. Create a left side page that
shows a diagram and an
explanation of the following types
of clouds
a. Cirrus
b. Cumulus
c. Nimbus/Cumulonimbus
d. Stratus
Water falling from clouds is called
precipitation. The air temperature
determines what type of precipitation
will occur.
Rain – if the temperature is above freezing
Snow –if the temperature is below freezing
Sleet – if snow passes through a layer of warm
air and then refreezes
Hail – forms high in the atmosphere and
gathers layers as it falls
Do Now
1. Create a left side page that
Proves you know what the types
of precipitation are and how they
form
The air pressure on any
one object on Earth
depends on how much air
exists above that object
Copy your
version of the
next slide onto a
left side page.
5. Wind
• It is a result of air moving from high to low
pressure regions.
• Warm air rises and cold air sinks
• Wind is measured with a Anemometer
• (Ann-E-mom-eater)
