| 释义 | albedo noun[ C or U ] physics specializeduk /ælˈbiː.dəʊ/ us /ælˈbiː.doʊ/ the amount of the light hitting a surface that it reflects back, especially the surface of a planet or other body in space: （尤指星体）反照率 Open water is one of the substances with the lowest albedo that we have on Earth.开阔的水面是地球上反照率最低的物质之一。 Scientists detected what could be a 2.5 percent decrease in Earth's albedo over the past five years.科学家们发现在过去五年中地球的反照率可能下降了 2.5%。 the albedo effect environment specialized the effect produced by the light and heat of the sun being reflected back from surfaces on Earth into the atmosphere: 反照率效应 The albedo effect - the reflection of 80% of the sun's heat by the snow and ice - keeps temperatures in the region cool.反照率效应，即冰雪反射80%的太阳热量，使该地区的温度保持凉爽。 Enceladus has an albedo greater than 90 percent, whereas the Earth and its moon have albedos of 38 percent and 12 percent, respectively. The object discovered by astronomers is believed to have a diameter of roughly 550 miles, based on assumptions of its surface reflectivity, or albedo. Sagebrush has a much lower albedo than wildflowers - that is, it reflects less sunlight back into space, causing even more warming. As the meadows vanish, a beneficial feedback loop - in which their high albedo helps to cool the world - is replaced by a harmful one. It is not entirely clear why the Arctic is warming much more quickly than other areas. One factor is probably albedo, or the heat-reflecting value of ice. Giving out light afire aura backlit beam beamy bioluminescence burnished flicker gleam glimmer glitter noctilucent non-glare non-luminous out-glitter overlit reflected ray shine spotlight wink You can also find related words, phrases, and synonyms in the topics: Astronomy Examples of albedoalbedo Effective albedo for gap feeding upper pinch in doublepinch at peak temperature ! The effect of perceived surface orientation on perceived surface albedo in binocularly viewed scenes. This energy balance depends on, among other factors, the planetary albedo. At the same time, the albedo differences themselves are likely to be related to differences in surface mineralogy and dust coverage. However, it is important to note that the global albedo pattern can change within only a few decades. The principal factors influencing soil temperatures are surface albedo and surface cooling. The amount of ice and snow is larger when the temperature is lower, so the lower the temperature the higher albedo. The figure shows the zonal-mean distribution, so the albedo and thermal inertia have been zonally averaged in the calculation. Information on the albedos and densities of those giants showing transits will be obtained. The difference in albedo is a factor of y10. Balancing the ice-albedo cooling and the greenhouse warming gives rise to two stable climate states. These high-albedo zones could be the remnant of sabkha or dusty materials composed of iron oxides, sulphates and other evaporates. It represents major gradients in key climatological parameters such as carbon flux, water flux and albedo. The planetary albedo is not a constant factor : it depends on the state of the climate itself, through the amount of clouds and ice. The red band was the least effective because of the in-uence of soil albedo and image vignetting. These examples are from corpora and from sources on the web.
