---|---|
a suspended particle that provides a surface for condensation | condensation nucleus |
formation of a large droplet by the combination of small droplets | coalescence |
the temperature at which condensation equals evaporation | dew point |
collection of water droplets or ice crystals suspended in the air | cloud |
heat energy that is absorbed or released during a phase change | latent heat |
the mass of water vapor contained in a given volume of air | absolute humidity |
the process by which a solid changes directly into a gas | sublimation |
a mass of water vapor that condenses near the surface of Earth | fog |
any form of water that falls to Earth’s surface from clouds | precipitation |
the ratio of actual water vapor content of the air to the amount of water vapor needed to reach saturation | relative humidity |
What is a low-altitude billowy cloud called? | a cumulus cloud |
Water vapor changes into a liquid in the process of | condensation. |
Precipitation formed in cumulonimbus clouds when convection currents repeatedly carry raindrops to high levels is | hail. |
The process in which the temperature of an air mass decreases as the air rises and expands is called | adiabatic cooling. |
Fog that results from the nightly cooling of Earth is called | radiation fog. |
The purpose of cloud seeding is to | induce precipitation. |
A condition in which water is cooled below its freezing point without going through a change of state is called | supercooling. |
In order to find out how intense precipitation will be, meteorologists use | Doppler radar. |
Large cloud formations associated with storm systems form by | lifting. |
What forms when the dew point falls below the freezing temperature of water and water vapor turns directly to ice? | frost |
