See gain.

Category:Meteorology

Solar and terrestrial radiation directed upward (away From the earth's surface); outgoing radiation.

Category:Meteorology

A hydrometeor consisting of an aggregate of microscopic and more-or-less hygroscopic water droplets suspended in the atmosphere. It reduces visibility to a lesser extent than fog. The relative humidity of mist is often less than 95 percent.

Category:Meteorology

An instrument that shows changes in humidity.

Generally, a measure of the departure of the mean daily temperature from a given standard, one degree day for each degree (

Category:Meteorology

Not a linear function of the relevant variables.

Category:Meteorology

The distance or length of flow of the air past a point during a given interval of time.

Category:Meteorology

A unit measure of electrical conduction. The facility with which a substance conducts electricity, as represented by the current density per unit electrical-potential gradient in the direction of flow. Electrical conductivity is the reciprocal of electric ...

Dew

Water condensed onto objects at or near the ground, due to the fact that their temperatures have fallen below the dew point temperature of the surrounding air, but not below freezing.

Category:Meteorology

The record of an aneroid barograph.

Category:Meteorology

A surface weather observation, made at periodic times, of sky cover, state of the sky, cloud height, atmospheric pressure reduced to sea level, temperature, dew point, wind speed and direction. amount of precipitation, hydrometeors and lithometeors. and s ...

Category:Meteorology

An instrument for measuring the relative speed of a fluid. It consists of a concentric pipe arrangement in which the inner pipe is open at one end and the outer pipe is perforated and closed at both ends. Each pipe is connected to a manometer. The unit is ...
