为什么不滴露珠形式在多云的夜晚吗?

非形成背后的原因滴露珠多云的夜晚是低于露点温度的不合格。它发生,即将离任的长波辐射(OLR)是不允许逃避由于云层。

我的问题是:如何云这样做,到底是什么?他们吸收OLR或者他们只是反映回地球本论文不允许地球温度低于露点吗?

我的第二个问题是关于露滴的形成在一个晴朗的夜晚。为什么牵涉全球变暖的温室气体允许OLR通过空间?做的温室气体变成透明的OLR在夜间清晰的夜晚吗?

云吸收热辐射和回送,这一些回来向地球([背后的预测:云如何影响温度][1])。白天变暖效应平衡的冷却效果挡住了阳光。他们不严格来说停止露水的形成,但他们使它不太可能。美国宇航局的气候对孩子的页面,“(有点像云是地球在大包装,温暖的毯子)[2]”。The 2nd question is about the effectiveness of greenhouse gases, and why we still get dew at night with all the extra greenhouse gases (GHGs) in the atmosphere. There are two parts to this. Firstly, the GHGs are not as effective as clouds when it comes to blocking the transmission of thermal radiation to space: they absorb in spectral bands related to the vibrational modes of the molecules in the gases, and there are gaps in these bands ("[windows][3]") which allow radiation to escape to space. Secondly, dew formation depends not only on the temperature at night, but also on the near-surface humidity. The increase is GHGs is, as we know, warming the Earth and this also leads to an increase in the amount of water vapour in the atmosphere, because warmer air can carry more water. To get dew formation we need a change in the temperature between night and day -- and GHGs don't contribute directly to this. There is an indirect effect which we see in [nights getting warmer faster than days][4]. There are several recent studies looking at the vapour pressure deficit (VPD) and showing an increase due to GHGs (e.g. [Ficklin and Novick][5]) -- VPD is a measure of the dryness of the air and an increases means less dew (though I have not found a reference that give direct evidence of reductions in the amount of dew). This drying of the night-time may also contribute to reduced harvests ([Sadok and Jagadish][6]).
