In Mongolia cheese and meat are still traditionally dried using the top of the ger (tent) as a solar dryer. [3] In these systems the solar drying is assisted by the movement of the air (wind) that removes the more saturated air away from the items being dried. [2] More recently, complex drying racks [4] and solar tents [5] were constructed as ...
A lantern is a source of lighting, often portable. It typically features a protective enclosure for the light source – historically usually a candle, a wick in oil, or a thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors.
Therefore, the sunbeam hitting the ground at a 30° angle spreads the same amount of light over twice as much area (if we imagine the Sun shining from the south at noon, the north–south width doubles; the east–west width does not). Consequently, the amount of light falling on each square mile is only half as much. Figure 3
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Heat waves are a natural part of Sacramento’s climate. But scientists agree that atmospheric warming caused mainly by burning fossil fuels has already increased the frequency, intensity and ...
Solar wind turbulence refers to the complex, chaotic fluid motions and magnetic field fluctuations observed in the solar wind plasma as it flows outward from the Sun. This turbulence plays a key role in heating the solar wind and accelerating charged particles throughout the heliosphere. [1] [2] [3]
At the time the UK established candlepower as a unit, the French standard of light was based on the illumination from a Carcel burner, which defined the illumination that emanates from a lamp burning pure colza oil (obtained from the seed of the plant Brassica campestris) at a defined rate. Ten standard candles equaled about one Carcel burner.
Slow wind (≈ 400 km/s) is confined to the equatorial regions, while fast wind (≈ 750 km/s) is seen over the poles. [1] Red/blue colors show outward/inward polarities of the heliospheric magnetic field. The solar wind is a stream of charged particles released from the Sun's outermost atmospheric layer, the corona.
