Question

When combined, the three synoptic air streams contribute to the development of rotating supercells. What characteristics make this possible?

Decreasing speed shear with height.

Winds that change direction in a clockwise manner with increasing height.

The streams lead to increasing density with height which promotes turbulence.

None of the above are correct

Explanation / Answer

When combined, the three synoptic air streams contribute to the development of rotating supercells. The characteristics which makes this possible is that (B)winds that change direction in a clockwise manner with increasing height.

Reason: When the winds change their direction with increasing heights, it leads to the development of wind shear which in turn helps the supercells to derive their rotation through the tilting of horizontal vorticity. This horizontal vorticity is in turn caused by the wind shear.
