- Mathematically written as

- The dimensions
are
![[f]=\frac{1}{[T]}](https://tex.z-dn.net/?f=%5Bf%5D%3D%5Cfrac%7B1%7D%7B%5BT%5D%7D)
as
![[T]=[S]](https://tex.z-dn.net/?f=%5BT%5D%3D%5BS%5D)
so,
![[f]=[S^{-1}]](https://tex.z-dn.net/?f=%5Bf%5D%3D%5BS%5E%7B-1%7D%5D)
The answer is A bc when warm, moist air from the Gulf of Mexico and cool and dry air from Canada
