Weather Flashcards
Humidity
The amount of water vapor held in the air
Relative humidity
The measured amount of water vapor that the air is holding compared to the amount it can hold at a given temperature
Dew point
The temperature at which air is saturated and condensation forms- it changes with the amount of moisture in the air.
Air masses
Large bodies of air that have the same properties as Earth’s surface over which it develops
Fronts
Boundaries between warm and cold air masses
Station model
Shows the weather conditions at 1 specific location
Isotherm
A line on a weather map that connects points of equal temperature
Isobar
A line on a weather map that connects points of equal atmospheric pressure
Meteorologist
Studies the weather by taking measurements of temperature, air pressure, wind, humidity, and precipitation; they predict weather.
Clouds
A cloud is a mass of water drops or ice crystals suspended in the atmosphere.
Difference between weather and climate
Weather is the daily change, and climate is the average is average over 30 years.
Humidity - over-saturated, saturated, undersaturated
Saturated air has a relative humidity of 100 percent. Over saturated is more than what it can hold and there will be some sort of precipitation and undersaturated holds less than what it can hold.
Types of severe weather
Thunderstorms, tornadoes, lightning, hurricanes, blizzard
How are clouds classified?
Clouds are mainly classified by shape, height, and/or precipitation.
Types of precipitation
Snow, rain, sleet, and hail
