What is meant by “Troposphere” in this lesson?The atmosphere: The troposphere is the lowest atmospheric layer and contains most weather activity.
What is meant by “Stratosphere” in this lesson?The atmosphere: The stratosphere lies above the troposphere and contains much of the ozone layer.
What is meant by “Air pressure” in this lesson?The atmosphere: Air pressure is force per area associated with the weight and motion of air.
What is meant by “Convection” in this lesson?The atmosphere: Convection transfers energy through bulk movement of fluids driven by density differences.
What is meant by “Humidity” in this lesson?The atmosphere: Humidity describes atmospheric water vapor, with relative humidity depending on temperature as well as vapor content.
What is meant by “Ozone protection” in this lesson?The atmosphere: Stratospheric ozone absorbs much incoming ultraviolet radiation, while ground-level ozone is a pollutant.
What is meant by “Air mass” in this lesson?Air masses and fronts: An air mass is a large body of air with broadly similar temperature and moisture properties.
What is meant by “Cold front” in this lesson?Air masses and fronts: A cold front occurs where advancing colder air displaces warmer air.
What is meant by “Warm front” in this lesson?Air masses and fronts: A warm front occurs where advancing warmer air moves over retreating colder air.
What is meant by “Stationary front” in this lesson?Air masses and fronts: A stationary front is a boundary with little overall movement between contrasting air masses.
What is meant by “Occluded front” in this lesson?Air masses and fronts: An occluded front develops when a cold front overtakes a warm front in a cyclone.
What is meant by “Front-related lifting” in this lesson?Air masses and fronts: Rising moist air can cool, condense, and produce clouds or precipitation along fronts.
What is meant by “Isobar” in this lesson?Interpreting weather maps: An isobar connects locations of equal atmospheric pressure on a map.
What is meant by “Pressure gradient” in this lesson?Interpreting weather maps: A pressure gradient describes pressure change over distance and helps drive wind.
What is meant by “Station model” in this lesson?Interpreting weather maps: A station model summarizes weather observations at a location using standardized symbols.
What is meant by “Radar observation” in this lesson?Interpreting weather maps: Weather radar measures returned signals used to estimate precipitation location and motion.
What is meant by “Forecast uncertainty” in this lesson?Interpreting weather maps: Forecast uncertainty reflects limits in observations, models, and atmospheric predictability.
What is meant by “Weather versus climate” in this lesson?Interpreting weather maps: Weather concerns short-term conditions; climate concerns statistical patterns over longer periods.
