Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.

The Earth-atmosphere system is radiatively cooled, emitting long-wave (infrared) radiation which balances the absorption of short-wave (visible light) energy from the sun. Convective transport of heat, and evaporative transport of latent heat are both important in removing heat from the surface and distributing it in the atmosphere.
Radiant heating and cooling. Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [1] "embedded surface systems", [1] "thermally ...
Los Angeles will feel the heat in the pattern as well, although temperatures are likely to stop well short of high marks well above 100 degrees earlier this month. On Sept. 6, the temperature ...
The most significant of which was the named heat wave, Cerberus Heatwave, which brought the hottest temperatures ever recorded in Europe. Starting on 10 July 2023, the record-breaking Cerberus anticyclone affected many European countries, with the effects felt most severely in parts of Southeast and Southwest Europe such as Cyprus , Greece ...
July 1743 heatwave in China - Beijing reached 44.4 °C (111.9 °F) on July 25, higher than any modern records. 11,400 people reportedly died. [1] July 1757 heatwave – Europe, hottest summer in Europe since 1540 and until 2003. [2][3][4] 1808 United Kingdom heat wave. 1881 North American heat wave [5] 1896 Eastern North America heat wave ...
Heat dome. A heat dome, over the United States. A heat dome is a weather phenomenon consisting of extreme heat that is caused when the atmosphere traps hot air as if bounded by a lid or cap. Heat domes happen when strong high pressure atmospheric conditions remain stationary for an unusual amount of time, preventing convection and precipitation ...
This allows the plant to generate about 38 percent of its rated capacity over the course of a year. [3] Thermal energy storage (TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months.
