Weather Analysis

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

Measuring Weather Data

• Radiosondes are balloon borne instruments that contain sensors that measure upper level conditions

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

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

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

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
