As the scientists point out, the combination of oscillatory signals together with resonance induced amplification may be the only possible form of long distance communication in certain cases.
Random lasers use light - diffusing materialoften in the form of a fine powderto trap light within the system long enough for amplification to occur.
Eschewing any conventional notions of beauty, or in many cases even taste, these works privilege instead a form of the grotesque, where identity often approximates a kind of caricature or mask: an exaggeration and amplification of reality.
Phillipson excels in her use of vernacular forms and the ability to seize the language of spectacle, to produce playful irony and reveal deeper truths by amplification, repetition and saturation.
The cooling trend due to reduction of CO2 and changes in climate associated with changes in the geography eventually allowed Northern Hemisphere ice sheets to form, whereafter the strong amplification of Milankovic was possible.
Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
«Arctic Amplification» form CO2 was not primarily from the (theorectical) loss - of - ice / increase in albedo meme so often used, but ratehr it began from the relative amounts of GHG's in the warmer, more water - vapor laden equatorial climates to the very dry Arctic regions.
It is then critical to consider whether the observed and expected dramatic declines in Arctic sea ice are causing fundamental changes in sensible heat and evaporation fluxes and influencing the magnitude and form of Arctic amplification.
Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).
Such forced, AMOC strength as well as the preferred ENSO phase can vary, leading to temporal temperature amplifications (e.g. in form of a decade long NAO + / - or El Nino / La Nina phase).
