An aerosol is the suspension of small solid particles or liquid droplets in the atmosphere.

Wind is the displacement of the air due to pressure differences.
So you can have a strong wind with a small aerosol content or a high content of aerosol with a light wind. Consequently there is no connection between wind and aerosol.

Why are winds ( vectors moving on the screen) in the option Aerosols , quite different from vectors in Winds or others options, at the same time in forecast ?

PM2.5 or NOx , for instance, have the same winds and vectors on the screen

THANK YOU

Hmm! maybe is a bug here!
Developers must see that ...
at the same forecast time (e.g. Tue 16/09Z)
For "wind": particles animation show a circular motion
over location A (Fethyie) and Northerly winds over B (Rodos)
while for "aerosol" the circular motion is located over B.

It seems that the wind direction in Aerosol layer is similar to the wind direction at 850hPa (~1500m).
The Ozone layer shows also a wind different from the wind at surface. It seems similar to the wind direction at 150hPa (~13500m).
I have not checked everywhere and I don’t know why there are such particularities.
