They are all doing different things!
Meteorology
The study of the Earth’s atmosphere
Work in : agriculture forestry aviation broadcasting military education
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
ClimateClimate
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
