A Peculiar Phenomena Called 'Cloud Seeding' Caused by Airplanes

It may be a possibility that the Earth’s natural weather patterns are beginning to change as the world becomes much more dependent on air travel. This is because airplanes cause a phenomenon known as ‘cloud seeding’ to happen which ultimately changes the formations and natural patterns that clouds take. Experts agree that these phenomena may also be leading to an increased amount of annual rainfall and snowfall.

At the turn of the 20th century airplanes became increasingly more popular as the technology became possible.  The excitement for the technological advancement was so anticipated that any thought towards the consequences of such a wonderful invention had not even been thought of.  However, as time progressed and the technology involved with the airplanes advanced the consequences of these flying machines became much more noticeable. 

Today much of the airplanes that fly around the world are powered by a non renewable resource that is a major pollutant.  The same can be said as for the majority of the world’s automobiles and machinery.  However, not only do the hundreds of thousands of planes that are flying around the world annually pollute on a catastrophic scale but the very fact that they fly may indeed be changing Earth’s natural weather patterns. 

A few decades ago large clouds with holes punched right through the middle of them became noticeable by a vast amount of people.  At first they were thought to be caused by U.F.O’s or from visitations of large spaceships from other planets.  However, as the phenomena continued so did the constant curiosity that many individuals soon sought out.  The research conducted from the curiosity of these strange ‘cloud holes’ revealed that a vast majority of them appeared near airports which led to the conclusion that it may very well be airplanes causing this phenomena. 

Clouds begin to form when super cooled water droplets are gathered and collected.  The clouds usually consist of a temperature between 32 and 40 degrees Celsius and will either begin to expel snow or rain depending on the temperature and how much moisture the cloud has gathered.  However, when jet engine planes pass through these clouds the water droplets begin to expand and cool from water droplets into ice which at the same time causes the clouds to grow heavier and ultimately alter the natural weather patterns.  This process of cloud shifting caused by planes has been recently referred to as ‘Cloud Seeding.’ 

At the National Center for Atmospheric Research located in Boulder, Colorado researcher Andrew Heymsfield concluded that planes have a 6% chance of ‘cloud seeding’ when flying on a daily basis, especially near airports.  While the number may not be high Andrew has noted that on a global scale over time this process of cloud seeding could become much worse thus changing the weather ever more so.  Many more clouds gather near airports that are located in higher altitudes.  This makes it nearly impossible for planes to avoid from passing through them while taking off and landing.  This fact has led to an increased amount of rain and snowfall each year according to the research conducted by Andrew and the National Center for Atmospheric Research.
