Im sorry but I do not have the links to his material offhand, I know he posted it on Flickr and a couple of other sites but I dont know where, Ill see if I can get that information from him for you and post it because its really interesting. Contrail formation is most likely at altitudes at or above 35,000 feet and at temperatures below -58F (-50C), therefore contrails are mostly formed by jets. In particular the size of the engines is a far better match. How high it will grow depends again on the three factors discussed above. The size of the circle only varies so different altitudes can be shown at the same point, but the smaller the circle, the higher the altitude. On top of that, most commercial jets cruise at 26,000 feet or higher, where temperatures are cold enough that the large volumes of condensed vapor instantly freeze and form visible contrail clouds. . The amount of moisture present in the atmosphere determines what type of contrail can form. Isnt azimuth correct, as you are referencing an angular measurement? Contrails may appear on clear or partly cloudy days because of jet engine exhaust that contains water vapor. Contrails found to impact climate change for a different reason - WBRZ Where do contrails form? Contrails are composed primarily of water, in the form of ice crystals. Fascinating. To back up your claims, you have the following evidence: I dont remember contrails looking like this. When the air up there is saturated with moisture, molecules of water vapor can condense onto the soot particles. Chemtrail conspiracy theory - Wikipedia Jet contrail shadows may appear to be cast by a low-altitude bright light shining upwards. However, the actual location can be inferred from the sun azimuth and the azimuth of the satellite. Stealth Planes Still Have a Very Visible Problem: Contrails Stay in the know with our Transportation newsletter. Me finding one normal contrail would prove nothing. Previous studies had produced false alarms, erroneously identifying a variety of features as contrails. In short, contrails are cloud-like streamers frequently observed to form behind aircraft flying in clear, cold, humid air. Contrails are line-shaped clouds or "condensation trails," composed of ice particles, that. Contrails - the Science and Myths - ThePlaneSpottersCommunity The atmosphere is a gaseous envelope surrounding and protecting our planet from the intense radiation of the Sun and serves as a key interface between the terrestrial and ocean cycles. The wing angle also matches the 747 better. Contrails | Earthdata You seem to have the perfect, pat answer to every question that is presented regarding chemtrails, too pat in my opinion but Im just one of those crazy chemtrail people I guess. It also explores the vulnerability of human communities to natural disasters and hazards. Yet while contrails may not increase atmospheric warming much on a global basis, the researchers discovered that contrails produced more significant regional warming. Photoshop has some fairly high quality enlargement algorithms, but there are a few different choices and each one produces different results. The wispy ice clouds formed by jet exhaust help trap heat near the Earth's surface. Very interesting. I watched many high flying jet in the clear sky, but none of them left a persistent contrail. Given the two facts above, you can see that it is almost impossible to accurately determine WHICH pixel really represents the edge of the plane. A small but growing number of Americans are moving to New England or the Appalachian Mountains, which are seen as safe havens from climate change.

Recognizing the connections between interdependent Earth systems is critical for understanding the world in which we live. Personally I do not know if the plane is a KC-135 as Brian Holmes states or if it is a 747-400 as you seem to believe it is, I believe that neither party has proven what type of plane it is but you certainly have succeeded in detracting the readers attention form the original subject which you presented as being Measuring the height of contrails but then I assume that was youre intention all along, correct? Its probably been debunked somewhere in English as well. Ill even help you and put in $20.00 towards the cost. Most important here is the wingspan measurement, 131 feet. Geophysical Research Letters 40: 612617, doi:10.1002/grl.50097. Now, Imperial College London-led research has found that. Clouds formed when water vapor condenses and freezes around small particles that exist in aircraft exhaust. There's a good chance that it was originally a jet contrail that became twisted and reshaped by atmospheric wind. Seems to me like thats a pretty big difference, considering air conditions can change drastically in that amount of space. Contrails, and other clouds directly resulting from human activity, are collectively named homogenitus.Depending on the temperature and humidity at the altitude the contrails form, they may be visible for only a few seconds or minutes, or may persist for hours and spread to be several miles wide, eventually resembling natural cirrus or . The terrestrial hydrosphere includes water on the land surface and underground in the form of lakes, rivers, and groundwater along with total water storage. Mysteries of Flight: Chemtrails - Plane & Pilot Magazine Low-flying planes at airshows often generate what look like contrails, but are simply special effects created by smoke. This mechanism is similar to the formation of cirrus uncinus clouds. Most cameras are storing their images in a compressed format (usually JPEG). 25,000 to 50,000 Feet Typical Altitude Range at Which Aircraft Fly 50,000 ft 40,000 ft Mt. Humans Have Broken a Fundamental Law of the Ocean. In fact, the word contrail is short for condensation trail.. Expert Answers: Exhaust contrails usually form at high altitudes; usually above 8,000 m (26,000 ft), where the air temperature is below 36.5 C (34 F). However I never really though of it as being particularly accurate. A short-lived contrail (left) forms immediately behind an airplane as a bright white line that lasts for only a short while if the air is somewhat moist (as compared to air that is very moist). My friend would tell me that I am wasting my time at a site like this and I can see how he would be right about that, I cant be bothered with such a closed mind as yours and I dont believe that it would be mentally healthily to continue with any further discussion on the subject with you. What evidence do you have, besides eyewitness accounts, that contrails were any different before 1999? 2,400 Contrail Clouds Stock Photos - dreamstime.com The wispy ice clouds formed by jet exhaust help trap heat near the Earth's surface. If planes fly through or over cirrus clouds that already exist naturally, you would minimize the radiative forcing from the contrails, Spangenberg said. Clouds Flashcards | Quizlet - Contrail Science Contrail Science, | - , Contrails Are Condensation, But Not Like Your Breath, Interactive Flight/Contrail Map Visualization. Clouds from aircraft exhaust can blanket the sky. According to a new study, however, changing the altitude of flights by just 2,000 feet could greatly reduce their effect on the environment. Mitigating the Climate Forcing of Aircraft Contrails by Small-Scale Diversions and Technology Adoption. They decided to include only contrails that persisted long enough to be visible in satellite data, yet maintained a linear shape. Clouds or Contrails [Space Apps 2016] All YOU have to do is find ONE chemtrail, and your theory is proved. Contrails, short for condensation trails, are line-shaped clouds produced by aircraft engine exhaust. Contrails are visible crystallized ice droplets in the form of clouds. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. Side note: in the summer time when you have a glass of ice water on the table, outside in the heat, it's the warm side that condensates. Contrails are a type of cirrus clouds consisting of predominantly ice particles. Thats a very important issue if you are investigating the science of contrail formation. You seem intelligent, do you have any idea of the horrendous things that the government has subjected the population to, done in secret over the years, if they are spraying these chemtrails, it would not be the first time that they have decided to subject the people of this country to nuclear, chemical or biological experimentation but then, if youre as intelligent as you seen to be, you already know this to be true but no doubt would like to believe that our government would never do something like that again and again and again,etc, etc. Conversely, the precipitation induced by persistent contrails in otherwise clear air (e.g., Figure 3 (a)) may result in moistening of the middle layers of the troposphere and drying of the atmosphere at flight altitudes. Not at all John, Id be delighted if more people took the time and effort to try and verify their assumptions particularly with regard to the height of the contrails. Storing it in giant concrete blocks could be the answer. Does contrail mean condensation trail? - sto.youramys.com Contrails are frequently seen criss-crossing the sky and are created from water vapour coming out of an aircraft's engines. Many of these flights route through the large East Coast hubs, and generate a mesh of contrails that waft across the skies toward Europe. Spokane, WA2601 N Rambo Rd.Spokane, WA 99224509-244-0110Comments? Please, take the blinders off, there is a far wider picture to be seen to all of this than you are presenting here but then again, I think you already know that, right? I suspect this is why it has never been done. I know, I know, talk is cheap so Ill leave it here but Ill be back with that info, count on it. We agree on everything else, but the identification of the plane has to be correct to calculate the height hence its the major issue here. Aerodynamic condensation trails at different altitudes ~ Contrails The width of the plane around the nose fits a lot better. Consider the following images, all taken at the same magnification. The Prius Gets a Redesign That Actually Looks Cool, 20 Viral TikTok Gifts That Are Actually Worth It, Elon Musk Embraces Twitter's Radical Fact-Checking Experiment, Jacques Valle Still Doesnt Know What UFOs Are. In fact, this shadow is normally cast on clouds below the jet and its contrail. Contrails form when hot, humid air from aircraft engines mix with colder surrounding air. Cirrus clouds warm the Earth. Why do some planes leave long trails, but others dont? Contrails dissipate at a rate contingent on weather conditions and the altitude of the contrail; contrails disappear faster in drier air than in humid conditions. Geophysical Research Letters 40: 595600, doi:10.1002/grl.50168. Contrail Avoidance and Mitigation Techniques, Debunked: KMIR6 Geoengineering the Skies (chemtrails), New Mystery Missile, Padre Island Texas. From it and the contrail height, the satellite azimuth is arctan (9.3/15.8) = 30 deg. These condensation trails may form by either of two distinct processes. Contrails are human-induced clouds that usually form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40C). So if you are in Denver, add 5,000 feet, if you are in Leadville, add 10,000. The overlaid schematic seems to match: So using this information they calculate the height of the plane at 20,000 feet, which they then claim is too low for contrails to form. The chase plane followed at 20 to 30 kilometers behind the A320, where the contrail was 1 to 2 minutes old and clearly visible: a merged cloud formed from the two contrails left by the two engines on the A320.
