• Your own Weather Forecasting– You can make your own predictions based on
your own observations.• Changing air pressure- You can expect a change
in the weather.– Falling pressure (Low)- might bring rainy weather– Rising pressure (high)- clear weather
• Clouds are a sign too.– Cumulonimbus- thunderstorms.– Cirrus- Low pressure might be approaching
Objective: I will be able to describe how technology helps predict weather.
• Weather Forecasting:• Meteorologists- are scientists who study
the causes of weather and try to predict it.– Interpret information from various sources
• Local weather observers.• Weather balloons.• Weather stations.• Weather Radar.• Satellites
– Computers analyze data and help prepare forecasts
Objective: I will be able to describe how technology helps predict weather.
• Weather Technology– Changes in technology
• Gathering Data• Computers Analyzing
Data
– Have made:• Short day forecasts for
up to 5 days are more reliable.
• Long range forecasts possible
Objective: I will be able to describe how technology helps predict weather.
• Weather Balloons– Carry a radiosonde-
high into the troposphere and stratosphere.
• Measures:– Air Pressure– Temperature– Humidity
Objective: I will be able to describe how technology helps predict weather.
• Doppler Weather Radar– Used to find the
location, movement and intensity of precipitation.
– Can detect what form of precipitation a weather system is carrying.
Objective: I will be able to describe how technology helps predict weather.
• Weather Satellites– First weather satellite
was launched in 1960.– Cameras on satellites
in the exosphere photograph:
• Earth’s surface• Clouds• Storms• Ice and Snow Cover
Objective: I will be able to describe how technology helps predict weather.
• Computer Forecasts– Widely used to help
forecast weather.
– Computers process the large amounts of data gathered quickly to help forecasters make predictions.
Objective: I will be able to describe how technology helps predict weather.
• Computer Forecasts– 1. Gathers reported conditions from weather
stations.
– 2. Works through thousands of calculations.• Surface conditions, temp, air pressure, wind speed
and direction and sunlight.
– 3. Revises forecasts with new data• Creates 12hr, 24hr, 36hr forecasts
Objective: I will be able to describe how technology helps predict weather.
• Weather Maps– A weather map is a “snapshot” of conditions
at a particular time over a large area.
– Generated by computers and radar information.
Objective: I will be able to analyze weather maps.
• National Weather Service Maps– Data from over 300 local weather stations
over the country is assembled into weather maps at the NWS.
– Information is converted into a Station Model.

Objective: I will be able to analyze weather maps.
On your paper- flip # 38 & 34 so that temp is 38 and dew pt is 34
• National Weather Service Maps– Curvy lines are drawn
where temperature and air pressure are equal (iso).
• Isobars- lines of equal air pressure. (inches of Hg or millibars)
• Isotherms-lines of equal temperature. °F or °C.
Objective: I will be able to analyze weather maps.
Objective: I will be able to analyze weather maps.
• News Paper Maps– Simplified versions of
NWS maps for the general public.
– Standard Symbols• Fronts• Areas of High and Lower
Pressure• Precipitation• Temperatures
Objective: I will be able to describe how technology helps predict weather.
Objective: I will be able to analyze weather maps.
• TV News– Information is
received from the National Weather Service or AccuWeather.
– Presented in a format the general public can understand.
Objective: I will be able to describe how technology helps predict weather.
• TV News– Typical Format:
• Current Conditions• Weather Across the
Local Area– Visible Cloud Satellite
and Doppler Radar
• Weather Across the Country
– Visible Cloud Satellite and US Doppler Radar
• Five Day Forecast– High/Low Temps– Weather Conditions
