Green Flash from the Sun :: weather sunset

Many think its alone a myth. Others think it is true only if its cause isnt known. Adventurers pride themselves on having seen it. Its a putting surface flash from the Sun. The truth is the green flash does equal and its cause is well understood. Just as the setting Sun disappears whole from vox populi, a last glimmer appears startlingly green. The effect is typically perceptible only from locations with a low, distant horizon, and lasts just a few seconds. A green flash is also visible for a rising Sun, but takes better timing to spot. A slight variant of this was caught in the higher up photograph, where much of the Sun was still visible, but the very top appeared momently green. The Sun itself does not turn partly green, the effect is caused by layers of the Earths atm acting like a prism.The Green FlashDefinition and rendering The green flash is an atmospheric refractive phenomenon where the top edge of the solarisebatheniness will momentarily turn green. It i s seen rarely by the naked eye, earlier because it requires specific conditions to occur, but also because it requires the observer to know what to look for. despite the name, there is no flash the event only lasts from a split up of a second to at the longest, a few seconds.The Basic driving force Refraction bends the light of the sun. The atmosphere acts like a jerry-built prism, separating the light into diferent colors. Blue light is bent more strongly than red. merely this refraction is very weak even at the horizon, which is why the sun isnt seen as being multi-colored in the daytime. The effect is magnified by the atmosphere, and at the horizon there is a lot of atmosphere between the sun and the viewer. Layering in the atmosphere causes an effect similar to a horizontal rounded lens the separation of the color bands is exaggerated in the vertical direction.Conditions The green flash is best observed when you have a clear view of the horizon, with no objects o r pollution in the line of sight. Usually you neediness to be able to see a distance of several miles out, virtually to the point where the curvature of the Earth defines the limit. Because of this, the green flash is most practically reported by the ocean.
