Hi all,

I don't like "from_direction" as a construct (I know it's already 
accepted for "wind_from_direction" and it is clearly explained in the 
notes but wouldn't

"direction_of_wind_vector_tail" or
"wind_vector_tail_direction or

  be more obvious?

(for the "to" direction you could use "head" or "arrow")

for gust, my vote would be


(Of course, I would also prefer "speed_of_wind_gust" to 
"wind_gust_speed" , and others probably don't).
