Is it true that an asymmetry exists between the northern and southern hemisphere jet streams?

Yes. Substantial scientific literature establishes that significant structural and behavioral asymmetries exist between the northern and southern hemisphere jet streams, notably regarding wind strength, storminess, and variability.

The analysis

The claim posits that an asymmetry exists between the northern and southern hemisphere jet streams. Paper [2] directly states that the Southern Hemisphere features a stronger jet stream and greater storminess compared to the Northern Hemisphere, driven by topography and ocean circulation. Paper [5] notes distinct hemispheric differences in jet stream waviness responses under climate change. Therefore, the claim is supported by the retrieved evidence.
