but the russian meters per second still makes no sense to me
unfortunately, in the MET world, and AWOS systems, meters per second as the worldwide standard.
AWOS systems at airports typically feed the local weather models in that standard.
Output for the airport is converted to the local standard, and runway specific.
METAR, TAF, winds aloft, surface analysis charts, etc use true north as the reference.
ATIS/AWOS/ASOS broadcasts, or any information a controller gives you over the radio, is magnetic.
