Outflow channels [SEP] located on astronomical body
Outflow channels
Outflow channels are extremely long, wide swathes of scoured ground on Mars, commonly containing the streamlined remnants of pre-existing topography and other linear erosive features indicating sculpting by fluids moving downslope. Channels extend many hundreds of kilometers in length and are typically greater than one kilometer in width; the largest valley (Kasei Vallis) is around long, greater than wide and exceeds in depth cut into the surrounding plains. These features tend to appear fully sized at fractures in the Martian surface, either from chaos terrains or
Astronomical Services Administration classified the system as Super Typhoon "Yoyoy" after the storm entered the agency's area of warning responsibility.
While around peak intensity, Typhoon Lupit had good outflow channels to the north and south. It had a 26 km (14 mi) eye, and gale-force winds reached a diameter of more than 740 km (460 mi). After peaking in intensity, Lupit underwent an eyewall replacement cycle, which caused the outflow to decrease and convection around the eye to diminish
