Mega Rayquaza's ability Delta Stream?

Question

New Mega Rayquaza has been revealed and it has the ability Delta Stream.
What are the details of this new ability?

Answer 1

When a Pokémon with Delta Stream enters battle, the Ability creates strong winds, a unique weather condition. The strong winds last as long as the Pokémon with Delta Stream is in battle.
Strong winds cause the moves Sunny Day, Rain Dance, Hail and Sandstorm to fail and cause the Abilities Drought, Drizzle, Sand Stream and Snow Warning to fail to activate. They also cause moves that are super-effective against Flying-type Pokémon to only deal normal damage to Flying types.

I write in Google for Delta Scream bulbapedia and it didn't show nothing.
Thanks great info to know.

This is gonna be interesting... basically an upgraded version of Air Lock, completely stopping the weather.  Also removes its 4x weakness to Ice (assuming same typing) to 2x, and its 2x weakness to Rock.  Potentially a strong doubles with other uber flying types.

Ambiguity is what happens to weather already on the field when Rayquaza comes out/mega evolves.  My guess it just shuts it down.

Answer 2

Delta Stream creates a Strong wind that lasts as long as the User is in battle

Strong Winds cause the moves, Sunny Day, Rain Dance, Hail, and Sandstorm to fail and cause the Abilities Drought, Drizzle, Sand Stream, and Snow Warning to fail to activate. they also cause moves that are super-effective against Flying type Pokemon to only deal regular Damage.
