Like the wind when at its height? (2,4,5)

'like' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'wind when at its height?' is the wordplay.
I cannot really understand how this works, but
'wind' could be 'blast' (blast is a kind of wind) and 'blast' is found within the answer.
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is found in the answer.
The remaining letters 'full' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'the' is the link.

Can you help me to learn more?
