Environment - Non Weather Related; Airport; Procedure
We were on short final landing runway 12 in Miami. The first officer was flying. MIA tower then cleared a heavy B777 for takeoff from runway 8R. Surface winds were approximately 050/10. Nearing the runway and seconds from flaring; our aircraft experienced tremendous turbulence associated from the takeoff thrust used by the departing B777 on runway 8R. The First Officer handled the significant changes in pitch/power well and managed to make a normal landing on runway 12.The turbulence we experienced was associated to the B777's takeoff thrust - it was not wake turbulence. The crosswind probably played a role in blowing it closer to our flight path. Had it been any worse we likely would have had to execute a go-around. Are there any minimum separation standards for landing aircraft and departing heavy aircraft from intersecting runways? Something perhaps to look at.
B737-800 Captain reported 'tremendous turbulence' from jet wash while landing on Runway 12 at MIA that was associated with a B777 departure on Runway 8R. Runway 8R and Runway 12 are close enough that the runway centerlines intersect near the runway thresholds.
