Thank you for your reply Nancy.
Can you answer any of my arguments in my previous message, perhaps solve the windfarm "chemtrail" conundrum?
Here we have the very same varying degree of trails depending on atmospheric conditions.
As explained in this post and this post
Did you know that you can look at a weather forecast, specifically the forecasted humidty at 300mb and predict whether the contrails from airplanes will be persistent or whether they will fade away quickly? It's not 100% certain as there are also other factors as play such as other layers of air/humidity, though.
The term "300 millibars" (mb) refers to a specific pressure level in the atmosphere, and it corresponds to a certain altitude above sea level. In meteorology, the atmosphere is often analyzed at various pressure levels rather than specific altitudes, because pressure levels provide a more consistent reference point for studying weather patterns.
I look at those 300mb charts almost daily when looking at these trails to understand and verify that the trails persist depending on the humidity at 300mb.
Today, directly south of Finland where the Kalingrad planes fly the air is dry so trails should not appear. But it's not very dry like it is for instance in the UK where trails right now should not be very persistent. To the north in Finland they might appear:
Or the other service that has the forecast, a little later today,
I recommend anyone interested in this phenomena do the same.
I've studied and documented these trails in Finland since about 2003, and for the past few years actively daily. I am also able to observe quite well because I spend a lot of time outside in the wilderness and archipelago.
Russian planes were forbidden to fly over Europe to reach Kaliningrad in 2022 so they now have to take a longer route there over the Baltic sea and there are now sometimes massive trails over the Baltic sea quite often, depending on atmospheric conditions.
