1. Weather, Weather Maps and Forecasting

2. Weather
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

3. Weather Forecasting Technology
Psychrometer
An instrument used for measuring the water vapor content of the atmosphere; a type of hygrometer.

4. Weather Instruments Anemometer Thermometer Doppler Radar Wind Sock
Barometer
Weather Satellite

5. Weather Map A weather map can show many different things. Temperature
High Pressure (clear)
Low Pressure (cloudy)
Isobars
Rain/Snow
Fog
Warm Front
Cold Front
Severe Weather- Hurricanes

6. 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.

12. Station Model
All over the United States, hundreds of weather observations are taken several times during the day.
Meteorologists need a way to get all of this detailed information into the smallest area possible on a weather map, so that several stations can be plotted for the same observation time on the same map, thus giving a ‘big picture’ of what the weather is doing at a snapshot in time.
Thus, the need for the station model.

16. National Weather Service (NWS)
From the NWS website you can view any kind of weather related information.
You can even see river stages and air quality.

17. National Oceanic and Atmospheric Administration (NOAA)
NOAA collects and analyzes weather data.
