Smoke Movement Control

[Kaito Ishikawa]

Hello. 
I am having trouble controlling Smoke.
I want to make Dust Smoke like Reference, but I can't figure out how to control the movement of the smoke, so I have to leave it to Simulation. In other words, it's all up to luck.
I would like to control the movement of Smoke so that it keeps this rough V line. Ⅰf there is a good way to create Source and control the movement, I would like to know how to do it.

Thank you,
Kaito Ishikawa

Maybe you could approach it as a rocket launch without flame or a helicopter downdraft expansion. There are a few setups on this site. Check my signature link.

Thank you for replying, Atom!
I checked your file.

This seems close to what I would like to do! But this would be too fixed and would eliminate the free movement of smoke due to building collapse.
How do you apply this?

Thank you, Tesan Srdjan!
I'll try it by using dissipate mask.
