Standard kanji spelling.
Kana spelling used when the kanji is not needed or for clarity.
Compound of 吹き (fuki, the continuative form of 吹く 'to blow') and 回し (mawashi, the continuative form of 回す 'to turn, send around'), literally 'blowing around'. The figurative sense comes from the idea of the wind's direction determining circumstances.
