A dispersive wave pattern on Jupiter's fastest retrograde jet at $20^\circ$S

open access: yes, 2016
A compact wave pattern has been identified on Jupiter's fastest retrograding jet at 20S (the SEBs) on the southern edge of the South Equatorial Belt. The wave has been identified in both reflected sunlight from amateur observations between 2010 and 2015,

The role of upper tropospheric jet streaks and lee-side cyclogenesis in the development of low level jets in the great plains [PDF]

open access: yes
A review of 15 cases of low level jets (LLJ) which developed in the Great Plains is presented. For 12 out of the 15 cases, a systematic upper level flow pattern was isolated which includes the existence of a trough over the southwest United States and ...
