Wind, fair, beginning to end, near ground (7)
I believe the answer is:
airflow
'end near ground' is the definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Maybe there's a link between them I don't understand?
'wind fair beginning to' is the wordplay.
'wind' is an anagram indicator.
'beginning to' becomes 'low' (I can't explain this - if you can you should give a lot more credence to this answer).
'fair' is an anagram of 'airf'.
'airf'+'low'='AIRFLOW'
Can you help me to learn more?
(Other definitions for airflow that I've seen before include "Wail for (anag.)" , "Wind (as on plane in motion)" , "Fan" , "Motion around moving plane/vehicle" , "Current" .)
