Hello again
Have you also noticed that the weather has changed a lot compared to the last 5 summers? This is very much the case in Vienna, Austria. I assume that the greatly reduced air traffic plays an essential role here.
Because for visual comparison: the contrails in the sky have become much less. That was always the initial spark for cloud formation. At the same time, the high, closed cloud cover prevented cooling at night. That was the cause of the tropical temperatures in Central Europe in recent years.
Today we have weather like 1980, for example.
Does anyone of you have any idea what the NAT is currently like and the frequency on it?
Who of you has watched the European sky from the flight deck over the past years and decades.
I myself have noticed an ever-increasing discoloration to brown in the Mediterranean, Central Europe and Great Britain airspace between 1995 and 2020. Around 2005 (boom in Europe) it was particularly blatant.
Happy modelling
