Unreferenced stub auto yes date December 2009 Atmospheric focusing is a phenomenon occurring when a large shock wave is produced in the Earth s atmosphere atmosphere , as in a nuclear explosion or large extraterrestrial object impact. The shock wave is refraction refracted horizontally by density variations in the atmosphere so that it can have impacts in localized areas much further away than the theoretical extent of its blast effect. In large bombs, some effects may thus be found hundreds of kilometers from the blast site such as in the case of the Tsar Bomba test, where damage was caused up to approximately 1,000 km away . This effect operates similarly to the patterns made by sunlight on the bottom of a pool, the difference is that the light is bent at the contact point with the water while the shock wave is distorted by density variations e.g. due to temperature variations in the atmosphere. Variations of wind can cause a similar effect. This will disperse the shock wave at some places and focus it at others. For powerful shock waves this can cause damage farther than expected the shock wave energy density will decrease beyond expected values inverse square law based on uniform geometry math 1 r 2 math falloff for weak shock or acoustic waves, as expected at large distances .

Image Windbuchencom.jpg right thumb 300px The effect of atmospheric icing on a tree. Atmospheric icing occurs when water Drop liquid droplets in the atmosphere freeze on objects they contact. This can be extremely dangerous to aircraft , as the built up ice changes the aerodynamics of the flight surfaces, which can increase the risk of a subsequent Stall flight stalling of the airfoil . For this reason, ice protection system s are often considered critical components of flight, and aircraft are often deicing deiced prior to take off in icy environments. Not all water freezes at convert 0 C F disp or . Liquid water below this temperature is called supercooling supercooled , and such supercooled droplets cause the icing problems on aircraft. Below convert 20 C , icing is rare because clouds at these temperatures usually consist of ice particles rather than supercooled water droplets. Below convert 42 C 1 , supercooled water cannot exist, therefore icing is impossible. Icing also occurs on tower s, wind turbine s, boat s, Drilling rig oil rigs , trees and other objects exposed to low temperatures and water droplets. Aircraft incidents see Category Airliner crashes caused by ice A number of aircraft crashes have been caused by ice. In other incidents icing was a contributory factor.

Unreferenced date December 2008 An atmospheric waveguide is an Earth s atmosphere atmospheric Fluid dynamics flow feature that improves the propagation of certain atmospheric wave s. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, for instance, westerly wind westerlies might be a good waveguide for east ward traveling waves, but might strongly dissipation dissipate west ward traveling waves, by increasing or decreasing their vertical wavenumber, respectively. Modification of the waves group velocity will change their meridional propagation speed, directing them more geographical pole polewards or more equator wards. Category Atmosphere ... more details
Atmospheric instability is a condition where the atmosphere is generally considered to be unstable and as a result the weather is subject to a high degree of variability through distance and time ref http www.ace.mmu.ac.uk eae Weather Older Stability of Air.html Stability of Air ref . Atmospheric stability is a measure of the atmosphere s tendency to encourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity. In unstable conditions, a lifted parcel of air will be warmer than the surrounding air at altitude. Because it is warmer, it is less dense and is prone to further ascent. In meteorology , instability is described by a lifted index and a K index . There are two primary forms of atmospheric instability ref http www.piercecollege.edu offices weather stability.html Explanation of Atmospheric Stability Instability by Steve W. Woodruff ref Convective instability Dynamic instability fluid mechanics Under convective instability thermal mixing through Atmospheric convection convection in the form of warm air rising leads to the development of clouds and possibly precipitation meteorology precipitation or convective storms . Dynamic instability is produced through the horizontal movement of air and the physical forces it is subjected to such as the Coriolis force and pressure gradient force .
