反射率  从非发光体表面反射的辐射与入射到该表面的总辐射之比,它是表征物体表面反射能力的物理量。绝对黑体的反射率为0,纯白物体的反射率为1,实际物体的反射率介于0与1之间,可用小数或百分数表示。    地-气系统的反射率,它包括地面、云和各种大气成分对太阳辐射的反?淠芰捌渥芎汀U庑┓瓷渎示龆ㄗ诺?-气系统吸收太阳辐射的百分数。 物体对太阳辐射的反射能力,因光线的入射角和波长而不同,气候学研究的是太阳辐射的全波段。    根据气象卫星的观测结果,整个地-气系统的反射率约为30%,即约有30%的太阳辐射能被反射回太空,其中三分之二是云反射的,其余部分则被地面反射和被各种大气成分所散射(见大气环流的能量平衡和转换)。云的反射率同云型和云层厚度有关,约在20~70%之间。陆面、土壤的性质和植被类型不同,也能使反射率改变,但这些差异一般不超过10~20%。而冰和雪的覆盖状况能引起反射率显著变化。例如,陆地被雪覆盖或洋面结冰时,将使其反射率增大30~40%,新雪面更可使反射率增大60%左右。原先无雪的地区如有积雪,则因反射率增大,将使太阳辐射能量的收入大约减小60%。这种影响随季节和纬度而不同,尤其明显的是,北纬50°以南的地区,当春季出现积雪时,上空平均将减少大约150卡/(厘米2·天)的热量收入。这样的热量收支变化,将产生明显的气候效应。     在极冰对气候影响的机制研究中,有人认为:冰雪-反射率-温度之间还存在"正反馈过程",即冰雪的覆盖增大地表的反射率,使地-气系统吸收的辐射减少,从而降低气温,而降温又将进一步使冰雪面积扩展,反射率继续增大,造成温度越来越低的现象。在这个正反馈过程的基础上建立的气候模式(见气候模拟),已用于解释古代冰期的形成和对未来气候趋势的推测。也有人认为:在实际大气中,还存在着"负反馈过程",它使气候具有稳定化的趋势(见极地气象学)。
