Hi Guys. I’ve been wondering recently why the weather has been so rudy awful, near constant cloud cover and raining most of the time; yeah I know its winter, but I remember winters being cold and crisp with clear skies and frozen ground you could not dig, when it was cloudy you had a good chance of snow that would stay around a while not just wet sleet and the occasional hail storm. Then I remembered when the Icelandic volcano Eyjafjallajökull ( try saying that when you’ve had a few ) that erupted in April 2010, causing enormous disruption to air travel across western and northern Europe and some of the atlantic over an initial period of six days.
The day after the planes were grounded the sky cleared and we had the most beautiful clear blue skies that I have seen in a long time. The day they let the planes fly again the sky was densely crisscrossed with con-trails and the weather shortly after turned back to rubbish again.
Was this just coincidence or was there something more to it. A quick google search will tell you that at any given time there are on average almost 10,000 aircraft in the air not counting private and military flights, and that around 500,000 to 600,000 metric tons of aviation fuel are used per day, an example from Boeing “A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters)”. The exhaust is mainly fine particulates and water vapour, ideal for cloud seeding, especially over warm oceans.
Just type into your search engine the phrase aircraft exhaust emmisions, you will find any number of articles on the subject.
In the above image pay attention to the flight paths over the oceans and note the corresponding cloud formation and lack of clouds where there are few flight paths.
I’m personally convinced that there is a connection between aircraft and cloud cover, after all; with that amount of aviation fuel being burned daily in our planets atmosphere you’d be fairly stupid not to think so.
