WAFC provides various types of data, including OPMET information, T4 charts (which are currently obsolete but some portions are still distributed due to legacy reasons), and GRIB and BUFR charts - these are Wind and Temperature charts and SIGWX charts (Significant Weather Chart) for SWH (high levels) and SWM (medium levels) .
ISO 3166-1 ( Codes for the representation of names of countries and their subdivisions – Part 1: Country codes) is a standard defining codes for the names of countries, dependent territories, and special areas of geographical interest. It is the first part of the ISO 3166 standard published by the International Organization for Standardization .
The International Standard Atmosphere ( ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations. It has been established to provide a common reference for temperature and pressure and consists of tables of values at various ...
This is a list of weather records, a list of the most extreme occurrences of weather phenomena for various categories. Many weather records are measured under specific conditions—such as surface temperature and wind speed—to keep consistency among measurements around the Earth. Each of these records is understood to be the record value officially observed, as these records may have been ...
For an ideal absorber/emitter or black body, the Stefan–Boltzmann law states that the total energy radiated per unit surface area per unit time (also known as the radiant exitance) is directly proportional to the fourth power of the black body's temperature, T : The constant of proportionality, , is called the Stefan–Boltzmann constant.
The global temperature record shows the fluctuations of the temperature of the atmosphere and the oceans through various spans of time. There are numerous estimates of temperatures since the end of the Pleistocene glaciation, particularly during the current Holocene epoch. Some temperature information is available through geologic evidence ...

In thermal engineering, Heisler charts are a graphical analysis tool for the evaluation of heat transfer in transient, one-dimensional conduction. [1] They are a set of two charts per included geometry introduced in 1947 by M. P. Heisler [2] which were supplemented by a third chart per geometry in 1961 by H. Gröber. Heisler charts permit evaluation of the central temperature for transient ...
