Transcript
Weather
•
Temporary behavior
of atmosphere
(what’s going on at
any certain time)
• Small geographic
area
What are some of the factors
that affect the weather?
• Air Temperature
• Wind
• Humidity
• Clouds
• Precipitation
Types of Precipitation
Rain
Sleet
Snow
Hail
METEROLOGY
• The study of weather is
meteorology
• Someone who studies
weather is called a
meteorologist
METEROLOGY
• Uses instruments to help study
the weather.
Weather Tools
The Most Common Weather
Tools Are:
• Thermometer
• Wind Vane
• Anemometer
• Barometer
• Rain Gauge
Thermometer
• A thermometer
is a weather tool
used to measure
the temperature.
Wind Vane
• By observing wind
vanes, we can
know the direction
of the wind.
Knowing the
direction of the
wind is an
important part in
predicting the
weather.
Anemometer
• Wind speed is an
important part of
weather.
• An anemometer is
a weather tool that
measures wind
speed.
Anemometer
• Wind speed is an
important part of
weather.
• An anemometer is a
weather tool that
measures wind
speed.
Barometer
• Barometers are
important to measuring
air pressure.
• Air pressure can help
you predict good or bad
weather.
• Changes in air pressure
indicates a change in the
weather
Barometer
• High pressure indicates
good or “fair” weather.
• Low pressure readings
indicate poor or bad
weather.
• Hurricanes and
“Nor'easters” have
very low pressure
readings!
Rain Gauge
• A rain gauge is a
weather tool used
to collect rain.
• Using
measurements on
the side of the rain
gauge, you can see
how many inches
it rained.
