Why is this a higher level than control water? This spell is pretty weak, disadvantage on ranged and grounding flying creatures. That's it? it could be so much stronger if you could hit tornado's or hurricane winds but you can't.

Yeah. This seems like a terrible ability. Prone on flyers after save. Disadvantage on ranged weapon attacks. Takes your concentration. Seems poorly balanced for 5th level. Even trying to account for some narrative coolness, the description kills utility... blinding debris? Nah! Impassable winds? Nope, just walk a little longer, unless you want to jump upwards, then have a boost...

i would errata/emend this in my campaigns to

1. prohibit corporeal flight in area with str save vs damage similar to other 5th level offensive spells,
2. additional prone effect for medium or smaller creatures str save (downdraft)
3. Unable to advance into the wind for large or larger creatures str save (headwind)
4. disadvantage on perception checks in area. Dex save or blinded whilst in area.
5. no range weapons in or out.

I like knocking flyers prone with a strength check. Do they fall straight down and take falling damage on fail? That could be nice. 

This spell is quite iconic and should have been a lot better. As written it would never get used in a game, and that is a real shame.

My changes:

You take control of the air in a 100-foot cube that you can see within range. Choose one of the following effects when you cast the spell. The effect lasts for the spell’s duration, unless you use your action on a later turn to switch to a different effect. You can also use your action to temporarily halt the effect or to restart one you’ve halted.

Gusts. A strong wind picks up within the cube, continually blowing in a horizontal direction you designate. Ranged weapon attacks that move against the winds direction have disadvantage on their attack rolls, while ranged weapon attacks that move with the wind deal an additional damage die of the weapons type. Any creature moving against the wind must spend 1 extra foot of movement for each foot moved, while any creature moving with the wind has it's movement speed increased by 10ft.

Downdraft. You cause a sustained blast of strong wind to blow downward from the top of the cube. Ranged weapon attacks that enter the cube or that are made within it are deflected downward and automatically miss. A creature must make a Strength saving throw if it flies into the cube for the first time on a turn or starts its turn there flying. On a failed save, the creature is knocked prone. Finally any creature moving within the cube must spend 1 extra foot of movement for each foot moved.

Updraft. You cause a sustained blast of strong wind to blow upward from the bottom of the cube. Ranged weapon attacks that enter the cube or that are made within it are deflected upward and automatically miss. Creatures that end a fall within the cube take no damage from the fall as the wind cushions their landing. Finally all creature's within the cube have their jump distance tripled.

I feel like this spell exists to counter Aarakocra. Imagine if some petty wizard made this out of pure spite

Big jumps or flattened like a pancake. Fun
