1. Weather Analysis

2. Gathering Weather Data
Meteorologists use the following tools to gather information about weather conditions
Thermometer-Measures temperature
Barometers-Measures air pressure
Storms generally form in low pressure systems
Anemometer-Measures Wind Speed

3. Measuring Weather Data
Radiosondes are balloon borne instruments that contain sensors that measure upper level conditions

4. Weather Radar Radar is used to track precipitation
Doppler Radars can measure wind speeds in storms
The Doppler effect is the change in wave frequency when waves move forward or away

5. Satellites Satellites orbit the Earth high above the surface
Can give good images of cloud cover
Detect thermal energy
Can be used to determine a clouds temperature and classification

6. Station Model
A station model is a record of weather data for a specific location and time
Shown on weather maps and allows a large amount of data to be shown in a small amount of space

7. Weather Maps
Meteorologists use isolines on weather maps to show areas of similar conditions
Isolines-Connect points of the same quantity
Isobars-Connect points of equal pressure
Isotherms-Connect points of equal temperature
