Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
Warming stripes (sometimes referred to as climate stripes, [3] [4] [5] [Note 1] climate timelines [6] or stripe graphics [7]) are data visualization graphics that use a series of coloured stripes chronologically ordered to visually portray long-term temperature trends. [2] [. Note 2] Warming stripes reflect a "minimalist" [2] [5] style ...
Dynamic line rating ( DLR ), also known as real-time thermal rating ( RTTR ), is an electric power transmission operation philosophy aiming at maximizing load, when environmental conditions allow it, without compromising safety. Research, prototyping and pilot projects were initiated in the 1990s, but the emergence of the "smart grid ...
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
The "degree Kelvin" (°K) is a former name and symbol for the SI unit of temperature on the thermodynamic (absolute) temperature scale. [1] Since 1967, it has been known simply as the kelvin, with symbol K (without a degree symbol). [2] [3] [4] Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
The temperature range (width) assigned to each color was chosen as 0.12 C to use use of all sixteen colors without clipping. The "border" temperature between red and blue stripes was chosen as the average of the highest and lowest temperature values (not as an average of a date range as is customary in warming stripes).
Weather map. A surface weather analysis for the United States on October 21, 2006. A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th ...
