'office' is the definition.
(weather bureau is a kind of office)

'survive to get desk' is the wordplay.
'survive' becomes 'weather' (I've seen this before).
'to get' means one lot of letters go next to another.
'desk' becomes 'bureau' (type of writing desk).
'weather'+'bureau'='WEATHER BUREAU'

'in met' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
