Weather device: article chaps set up before remote storms (10)
I believe the answer is:
anemometer
'weather device' is the definition.
(device for measuring wind speed)
'article chaps set up before remote storms' is the wordplay.
'article' becomes 'a' (example of the part-of-speech).
'chaps' becomes 'men' (I've seen this before).
'set up' is a reversal indicator.
'before' says to put letters next to each other.
'storms' is an anagram indicator.
'men' written backwards gives 'nem'.
'remote' anagrammed gives 'ometer'.
'a'+'nem'+'ometer'='ANEMOMETER'
(Other definitions for anemometer that I've seen before include "Air Force display unit?" , "Wind speed gauge" , "Wind speed measurer" , "Windspeed measurer" , "Wind speed instrument" .)
