I have downloaded Ugrib. Thanks so much for the recommendations. It looks like very good.
Do you know where I can find explanations aboiut the arrows showing on a view ?
They are symbols related to weather forecast, I guess winds directions and force, and I would like to be sure about what I am reading.
Arrow in red, green, dark green, blue what differences?
End of arrow 2 or 3 small ??? cannot figure a name for this (Sorry I am French and when it starts very technical, my english is bad)
It looks like arrows and colors are associated.
3 for red, 2 for light green, 1 for dark green, 1 for blue.
I am guessing that more arrows, higher the winds. And for direction not sure.
Is there an option to see pressure for isobars?
That is a very nice tool, thanks for sharing.
