Light passing through thin clouds made up of uniform size water droplets can cause diffraction rings to appear around the sun and moon.

The photo (right) shows a diffraction ring around the rising sun. A layer of thin clouds that caused it, and it dramatically disappeared when the sun rose high enough.

This 1/10th second picture shows an overexposed full moon. The moon is in thin clouds which glow with a white disk surrounded by a red ring. A longer exposure would show more faint colors outside the red ring.

Atmospheric ductIn telecommunication, an atmospheric duct is a horizontal layer in the lower atmosphere in which the vertical refractive index gradients are such that radio signals (a) are guided or focused within the duct, (b) tend to follow the curvature of the Earth,Atmospheric reentryAtmospheric entry is the transition from the vacuum of space to the atmosphere of any planet or other celestial body. The term is not used for landing on bodies which have no atmosphere e. Atmospheric reentry refers to the return to an atmosphere previousAtmospheric pressureAtmospheric pressure is the pressure caused by the weight of air above any area in the Earth's atmosphere. Standard atmospheric pressure atm is discussed in the next section. Air masses are affected by the general atmospheric pressure within the mass, cre
Atmospheric waveguideAn atmospheric waveguide is an atmospheric flow feature that enhances the propagation of certain atmospheric waves. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, fAtmospheric sciencesFluid dynamics Atmospheric sciences is an umbrella term for the study of the atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Meteorology is the field of weather forecasAtmospheric pressure demonstrationThis is How-to about an atmospheric pressure demonstration .
