1. Starter 1.What are hurricanes in the Western Pacific called? 2.What are hurricanes in the Indian Ocean called?

2. Weather Analysis

3. 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

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

5. 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

6. 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

7. 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

8. 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
