Weather Analysis Gathering Weather Data Meteorologists use the

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 ▫ Sling Psychrometer – Measures Relative Humidity

Radiosonde • Radiosonde – Instrument carried by a balloon uses sensors to measure the atmosphere ▫ Gathers information about the upper atmosphere ▫ Transmits the information by radio

Radar • Radar - Radio Detecting and Ranging ▫ Radio waves are sent out and detect water droplets ▫ Meteorologists can determine the location of the storm • Doppler Radar – Uses the Doppler Effect to determine the speed of the wind and rain

Satellites • Satellite – Device that orbits the Earth and makes measurements of the atmosphere ▫ Cloud Cover ▫ Temperature ▫ Can track a storm

Station Model • A station model is a symbol on a weather map that shows all of the conditions of a particular area ▫ Shows a large amount of data in a small amount of space

Weather Maps • Weather map – A map that shows the weather of a particular area • Isolines – Lines on a map that connect similar points ▫ Isobars-Connect points of equal pressure ▫ Isotherms-Connect points of equal temperature
