The rate of decrease of temperature with elevation, −∂T/∂z, or occasionally ∂T/∂p, where p is pressure. The concept may be applied to other atmospheric variables (e.g., lapse rate of density) if these are specified. The environmental lapse rate is determined by the distribution of temperature in the vertical at a given time and place and should be carefully distinguished from the process lapse rate, which applies to an individual air parcel. See autoconvective lapse rate, superadiabatic lapse rate.
Industry:Weather
A layer of intermittent turbulence and overshooting thermals at the top of the convective mixed layer where the free atmosphere is entrained into the top of the boundary layer. The entrainment zone is thinner when a stronger temperature inversion caps the boundary layer and thicker when turbulence and thermals are more vigorous.
Industry:Weather
A substance that occurs naturally in the environmental system that can be used as a tracer.
Industry:Weather
The erosion of land surfaces by wind-driven dust or sand. See also corrasion.
Industry:Weather
A French satellite, launched in August 1971, that collected meteorological data from 500 free- flying constant-level balloons to study hemispheric circulation patterns.
Industry:Weather
Data that help to characterize the conditions under which the remote sensing data were collected, that may be used to calibrate the sensor prior to analysis, or that include such information as the positioning and spectral stability of sensors, sun angle, or platform attitude.
Industry:Weather
Lake that becomes dry during a dry season or in dry years.
Industry:Weather
A stream channel that carries water only during and immediately after periods of rainfall or snowmelt. Compare intermittent stream, perennial stream.
Industry:Weather
The position of a satellite in space as a function of time. Ephemeris data are used for gridding satellite imagery. Since ephemeris data are based solely on the predicted position of the satellite, an ephemeris is susceptible to errors from vehicle pitch, orbital eccentricity, and the oblateness of the earth.
Industry:Weather
The layer of water above the thermocline in a freshwater body.
