Problems between Maps and Meteograms

Ichnos Centro Meteo

Good evening
I'm sorry for my poor english

As you can see, using distance and planning:

-in img1, along the route between point 4 and 5, on the map at sea level the wind blows from WNW at the right angle to the isobars, as it should be in a normal situation; but the data shown on the meteogram are completely incorrect, with winds blowing and waves come from NE.

-You can find the same problem in Airgram, VFR, IFR, Boat, in every "gram" the wind at all level it would seem that they come from the wrong direction.

It almost seems that:

the Divergence from the center of High pressures and the Convergence towards the center of Low pressures is not respected.

Hello,

I’m quite sure it is not a bug. Just a wrong setting of the wind direction reference.
See More option and set the direction reference (wind barbs) to North up.

In addition you may look at this related discussion to understand the 3 different options:
