Warming weather Malta embodies (7)
I believe the answer is:
thermal
'warming' is the definition.
(I've seen this before)
'weather malta embodies' is the wordplay.
'embodies' says the answer is hidden in the clue.
'THERMAL' is hidden within 'weather malta'.
(Other definitions for thermal that I've seen before include "Caloric" , "Type of air current" , "help for glider" , "Her malt became heat-related" , "Upward current of warm air" .)
