Earth’s Atmosphere: Lesson 5 and Reinforcement, Lesson 6 and Geolab

Ch 11/12/13 Earth’s Atmosphere Study Guide Name: ______________________________ Date: ___________ Period: ____ Lesson 5 and Reinforcement (USA Weather Map) … 1. Describe the four types of fronts, identify the symbols for each, and describe the weather each causes. What happens to the temperature of an area after each passes? a. Cold - Blue line with triangles, brings thunderstorms, then cooler and drier conditions b. Warm - Red line with half-circles, brings light to moderate precipitation, then warmer and more humid conditions c. Stationary - Alternating red and blue lines with semi-circles and triangles, leads to cloudy skies and prolonged precipitation with minimal temperature changes d. Occluded - Purple line with alternating triangles and semi-circles, brings strong winds, widespread precipitation, and varying temperature changes 2. Describe the 2 types of pressure systems. Recognize the symbol for each. What kind of weather is associated with each? a. High pressure - Blue "H," brings fair weather with clear skies, light winds, and cooler temperatures b. Low pressure - Red "L," brings unsettled weather with clouds, precipitation, and sometimes strong winds, along with milder temperatures Lesson 6 and Geolab (Weather Map)… 1. Know the data collected by the following weather instruments – a. thermometer b. barometer c. anemometer d. hygrometer 2. Temperature Atmospheric pressure Wind speed and direction Humidity Height of cloud base e. ceilometer What type of data do radiosondes collect – in general and specifically? Radiosondes collect both general atmospheric data (temperature, pressure, humidity) and specific vertical profiles of these parameters as they ascend through the atmosphere attached to weather balloons 3. What is radar? It is a system that uses radio waves to detect the presence, direction, distance, and speed of objects, including precipitation and other meteorological phenomena. What does the word stand for? Radar stands for "Radio Detection and Ranging." For what is radar used to track? Radar is used to track weather patterns, including rainfall, storms, and other atmospheric disturbances 4. What is Doppler radar used for? Doppler radar is used to measure the velocity of objects, including precipitation particles, by detecting the shift in the frequency of the radar signal caused by the motion of the objects. It is commonly used in weather forecasting to track the movement and intensity of storms, including tornadoes and severe weather 5. Know the terms – a. isobar - Lines on a weather map connecting points of equal atmospheric pressure b. isotherm - Lines on a weather map connecting points of equal temperature 6. Be able to read a station model. (There will be a station model on your test!) A station model is a symbolic representation of weather data at a specific location on a weather map. It includes information such as temperature, dew point, wind speed and direction, atmospheric pressure, cloud cover, and weather conditions 7. Know the difference between a digital and analog forecast. A digital forecast is generated using computer models that analyze vast amounts of meteorological data to predict future weather conditions. An analog forecast relies more on past weather patterns and trends to make predictions. Digital forecasts tend to be more precise and utilize current data, while analog forecasts may incorporate more long-term climate trends and historical patterns
