SWRP Sounding supercooled warm-rain process
Below is a sounding that typically results in freezing rain through Supercooled Warm Rain Processes (SWRP). Throughout the sounding profile, the temperature never exceeds 0C (32F).
sounding
Any probe of the environment made to obtain information at various levels.
Sounding - A plot of the vertical profile of temperature and dew point (and often winds) above a fixed location (Fig. 6). Soundings are used extensively in severe weather forecasting, e.g.
Sounding-based Stability Index - an index calculated from balloon observations (e.g., CAPE, Lifted Index, K-Index, Bulk Richardson Number, Total-Totals Index) that provide guidance about the potential organization, type, ...
soundings - See atmospheric sounding.
source - In hydrodynamics, a point, line, or area at which mass or energy is added to a system, either instantaneously or continuously.
Sounding - A temperature profile of the atmosphere measured by a radiosonde. Also can indicate wind and dew point.
SST - Sea Surface Temperature. The temperature of the near surface ocean water.
Sounding - A set of data measuring the vertical structure of an atmospheric parameter (temperature, humidity, pressure, winds) at a given time.
SOUNDING A plot of the atmosphere, using data rom upper air or radiosonde observations. Usually confined to a vertical profile of the temperatures, dew points, and winds above a fixed location.
Sounding: The vertical distribution of temperature, moisture, wind speed (and direction) over a location.
Sounding An upper-air observation, such as a radiosonde observation. A vertical profile of an atmospheric variable such as temperature or winds.
SOUNDING- Profile of temperature, dewpoint and wind with height measured by a weather balloon

SPIN UP- An increase in the rotation rate over time (i.e. spin up of vorticity, tornado spin up) ...
Soundings Continuous altitude measurements that provide profiles of such variables as temperature, humidity, and wind speed.
Southern oscillation Opposing swings of surface air pressure between the central and western tropical Pacific Ocean.
sounding—In meteorology, an upper-air observation; a radiosonde observation.
Sounding "Sounding" derives from both Latin and Anglo-Saxon terms meaning to submerge something in order to detect depth. In meteorology, the term "sounding" refers to an upper air observation or a complete radiosonde report.
kite sounding"Soundings by means of kites, sometimes used for measuring certain weather elements in the lower atmosphere.
kloof wind"A cold southwest wind of Simons Bay, South Africa.
SOUNDING - Data gathered by a weather balloon or similar instrument for the winds and conditions aloft. Very important for upper level wind and temperature or pressure profile determination.
Some sounding rockets are available both with or without dart. The version without dart is able to transport more payload, but reaches lesser height.

Applications ...
[Slang] A sounding characterized by extreme instability but containing a cap, such that explosive thunderstorm development can be expected if the cap can be weakened or the air below it heated sufficiently to overcome it (the convective temperature).
(EL) On a sounding, the level above the level of free convection (LFC) at which the temperature of a rising air parcel again equals the temperature of the environment.
The area on a sounding representing the layer in which a lifted parcel would be warmer than the environment; thus, the area between the environmental temperature profile and the path of the lifted parcel. See sounding.

Stability IndexThe overall stability or instability of a sounding is sometimes conveniently expressed in the form of a single numerical value. Used alone, it can be quite misleading, and at times, is apt to be worthless.
They are obtained on a sounding by computing the area enclosed between the environmental temperature profile and the path of a rising air parcel, over the layer within which the latter is cooler than the former.
Teardrop balloon A sounding balloon which, when operationally inflated, resembles an inverted teardrop.
Such a chart typically is used to plot atmospheric soundings, and to estimate potential changes in temperature, moisture, etc. if air were displaced vertically from a given level.
It is computed from the morning (12Z) soundings from RAOB stations across North America. The index is composed of a stability term and a moisture term. The stability term is derived from the temperature difference at two atmosphere levels.
Environmental Temperature SoundingAn instantaneous or near-instantaneous sounding of temperature as a function of height.
Obtained through a rawinsonde sounding or comparable method, and exhibited in a skew t-log p diagram.
GSFC also directs operations at the Wallops Flight Facility on Wallops Island, Virginia, which each year launches some 50 scientific missions to suborbital altitudes on small sounding rockets.
Indeed, once upper-air soundings became available on a regular basis, it could be seen that this uniformity extended vertically, such that each air mass has a distinct vertical profile of temperature and humidity.
Atmospheric Infrared Sounder: advanced sounding instrument designed to retrieve vertical temperature and moisture profiles in the troposphere and stratosphere achieving a temperature retrieval accuracy of 1 degree C with a 1 km vertical ...
Convective Available Potential Energy (CAPE or B+) It defines the vertically integrated positive buoyancy of an adiabatically rising air parcel on a sounding.
Wiresonde- an atmospheric sounding instrument that is used to obtain temperature and humidity information between ground level and height of a few thousand feet; ...
EQUILIBRIUM LEVEL (or EL)
On a sounding, the level above the level of free convection (LFC) at which the temperature of a rising air parcel again equals the temperature of the environment.
A line of constant potential temperature on a thermodynamic chart. See sounding.
