Teaching high school is like herding cats!!

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
