  • Weather: The daily conditions of a particular area: temp, rain, pressure, wind, etc.
  • Climate: the measure of weather over a very long period of time—at least 100 years
  • Meteorology- the science of studying weather

what is a weather forecast
What is a weather forecast?
  • Forecast: A prediction of weather over the next 5-10 days.
what is a meteorologist
What is a meteorologist?
  • Meteorologist: A person who observes the atmosphere, collects data, and makes predictions—forecasts—based on the data.
  • Meteorologist = weather person
  • You know them as weathermen and weatherwomen.
what do meteorologists measure
What do meteorologists measure?
  • Air pressure
  • Humidity
  • Precipitation
  • Temperature
  • Wind speed
  • Wind direction

weather balloons
Weather Balloons
  • Weather balloons: Carry equipment as high as 30 km above the Earth’s surface
  • Measure temperature, air pressure, relative humidity, wind speed, & direction
thermometer
Thermometer
  • Thermometer: Used to measure:
    • air temperature
barometer
Barometer
  • Barometer: Used to measure air pressure
psychrometer
Psychrometer

An instrument used for measuring the water vapor content of the atmosphere; a type of hygrometer.

  • Used to measure wind direction
wind vane weather vane
Wind Vane/Weather Vane
  • Used to measure wind direction
radar
Radar
  • Used to find location, movement, kind & amount of precipitation
weather satellite
Weather Satellite
  • Orbit the Earth & send information back to Earth; used to track storms, wind speed, humidity, & temperature @ different altitudes
collecting analyzing weather data
Collecting & Analyzing Weather Data
  • 2 groups who gather information:
    • National Weather Service (NWS)
    • NOAA (National Oceanographic & Atmospheric Administration)
slide20
NWS
  • Produce maps based on information gathered from over 1,000 weather stations nationwide
station model
Station Model
  • A small circle that shows the location of a weather station
  • Surrounding the small circle is a set of symbols & numbers that represent weather data

Warm Front
  • Represented by half-circles on a line:
high pressure
High Pressure
  • Usually brings clear, sunny weather
low pressure
Low Pressure
  • Bring rainy weather

  • Lines that connect points of equal pressure on a weather map
slide29

ISOBARS- Certain weather maps allow us to view High and Low pressure systems that control the weather. An isobar is a line connecting locations of equal barometric pressure. Isobar maps show where pressures are relatively high and low, and show us where pressure changes are gradual or dramatic over a distance.
