No, but the vertical speed comes from the ADIRS. So, it won't do get a spike. It's not barometric.

About advanced weather I was confused more than year And here https://forum.flightgear.org/viewtopic.php?f=69&t=27065 is solution for automatic start of the AW engine.

EDIT :
I found better solution :

Autostarting Advanced Weather

Currently, the choice of Advanced Weather is not saved through sessions. To enable this, use --prop:/local-weather/autostart=1 and then check the property in the Nasal init code using getprop("/local-weather/autostart"), if it's true, invoke the same routines as the dialog's ok/apply buttons (see the corresponding bindings), and you'll end up with a fully optional autostart-feature. To retain the setting, set the userarchive attribute to true. Yes, it's not straightforward.

EDIT 2 :
For me, second solution probably doesn't work.
