1. There appeared a strange face in the window.
2. In order for a tonado to occur, there needs to be some type of rising air.
Q1) Can I say "A strange face appeared in the window" instead of #1? If so, why do we say #1 instead of it?
Q2) What is the function of "there" in #2?
Can it be rephrased?
Thank you for the answer.
'there' in #2 is not non-referencial? Does 'there' have any meaning? or why is it used as a subject?
