Met expectations of what recreates waves (7,8)
I believe the answer is:
weather forecast
'met expectations of what recreates waves' is the definition.
I can't tell whether this definition defines the answer.
'of what recreates waves' is the wordplay.
'waves' indicates anagramming the letters.
'of'+'what'+'recreates'='ofwhatrecreates'
'ofwhatrecreates' is an anagram of 'WEATHER FORECAST'.
Can you help me to learn more?
(Other definitions for weather forecast that I've seen before include "Predicton" , "prediction" , "Met objective" , "item after news" .)
