Weather
• The state of the atmosphere at any given
time and place
Includes:
-clouds
- precipitation
-wind speed and direction
-temperature
-air pressure
-dew point
- humidity
Weather Instruments
Climate
The general condition of
the atmosphere over
many years
Determined by :
Latitude
Jet stream
Inland/Coastal
Topography
Rain god - Tlaloc
•Name means- he who
makes things sprout
•Greatly feared- send
drought, severe weather
or good conditions
Barometer
• Measures air
pressure
• Average pressure at
sea level is 29.92 in
or 1013.25 mb
Psychrometer or Hygrometer
• Measures relative
humidity or amount of
water vapor in the air
• Effected by
temperature
as T increases
H decreases
Rain Gauge
• Measures amount of
precipitation
• Not accurate over a
wide area
• 1 inch of rain =
10 inches of snow
Thermometer
• Measures air
temperature
Weather Vane
• Shows wind direction
• Arrow with tail, tail
catches wind, arrow
points into the wind
• Points in direction
wind comes FROM
Anemometer
• Measures wind speed
• Rotation of cups
translated into mph
Nephoscope
a grid-like measuring
instrument for
measuring the
altitude, direction, and
velocity of movement
of clouds
Ceilometer
• A device that uses a
laser (or some other
light source) to
determine the base
level of the clouds
• It finds the CEILing
Radiosonde
• Weather instrument
package carried aloft
by a weather balloon
• Contains
psychrometer,
barometer,
thermometer
RADAR
• Electronic device that
transmits radio waves
in the form of a beam
• Can detect
precipitation and
storms
Doppler Radar
• Gives precise location
of a storm and tracks
its movement and
intensity
Satellites
• Remain above fixed
point on Earth
• Monitor a regions
weather

An Anagram
• Forecasting the weather
• BECOMES:
• Wet or fine, he gets a chart
