Speaker: Feng Ding
We are glad to have Feng Ding to introduce a recent debate regarding whether Juno’s gravitational measurements can be used to infer Jupiter’s jetstream structure.
During the discussion, Feng will cover the below points:
1. The Juno gravitational measurements have revealed that Jupiter’s gravitational field is north-south asymmetric.
2. Kaspi et al. (2018) invert the measured gravity values into the wind field and show that the observed jet streams extend from the cloud level down to depths of thousands of kilometers.
3. A recent paper by Kong et al. (2018) argues that the antisymmetric gravitational field could be explained by both the shallow and deep jet scenarios, which demonstrates the nonunique nature of the gravity inverse problem.
