Actually, I think that direction of wind flow, and currents, would tend
to govern the ash flow, and not a whole lot else - by a couple of weeks
after any given event. I think that conceivably it would matter if
events were at mid latitude, equatorial, or elsewhere, because I think
that it did in the case of the Sumatra volcano that caused the Year
Without a Summer. (Sumatra had more than one catastrophic volcano in the
19th century.) Otherwise, once dust and gas got into the atmosphere, it
was everywhere.

If it can assumed that the Deccan Traps and the Chicxulub impact
took place at approximately the same time,
Again: no, they did not. The main episode of eruptions was over 100,000
years before the impact, and smaller episodes happened long before and
after.
