evaporation | the process of turning from liquid into vapor. |
humidity | a quantity representing the amount of water vapor in the atmosphere or a gas. |
relative humidity | the amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature. |
psychrometer | a hygrometer consisting of a wet-bulb and a dry-bulb thermometer, the difference in the two thermometer readings being used to determine atmospheric humidity. |
dew point | the atmospheric temperature varying according to pressure and humidity below which water droplets begin to condense and dew can form. |
cirrus | cloud forming wispy filamentous tufted streaks (“mare's tails”) at high altitude, usually 16,500–45,000 feet 5–13 km) 2. |
cumulus | a cloud forming rounded masses heaped on each other above a flat base at fairly low altitude. |
stratus | cloud forming a continuous horizontal gray sheet, often with rain or snow. |
