Summary of Observation Constraints and Model Output

Parameter	Avg. Spacecraft Observations	Case 1	Case 2	Case 3
Central Graphic Lat.	16.5 ± 0.5	17	17	17
Lat. Extent (°)	2.5	2	1.4	2
Wavelength (°)3	1.2	~1	~1	~1
Long. Extent (°)1	~5 to >50	8	4	4
Speed (m/s)	−15 ± 15	−17.5	−7
Lifetime (Days)2	≥12	20	8	20

Notes:

^1.The length of individual wave trains is difficult to distinguish because of the background cloud features.

^2.The lifetime observed in amateur data may exceed 30 days.

^3.In the simulations the wavelength changes as a function of time as seen in Fig. 7
