Hi

It is possible to find somewhere vertical air movement direction and speed?

Thank you for explanation.

How it is comlex.

It seems to me it is also an approximation.
Even we place barometers at same heigth, the reading will vary.

Yes, I understood it.
I think this is not very practical for ordinary people.

746 is ok
But windy gives 767.

Koltsovo airport is about 10 km from my location. I think this is insubstantial.
Unfortunately, all mercury barometers were taken from us. They say it is not environmentally friendly.

Hi
My wether station report 743mm
Local wether agency 741mm

Windy 769mm

Best regards
