Hawaiian island lee cloud line, and cold frontal rope cloud

Two interesting semi-linear cloud features were apparent in the vicinity of the Hawaiian Islands on 06 November: (1) a cloud line to the lee of the Big Island of Hawaii, due to easterly “trade winds” within the marine boundary layer converging after flowing around the island (also note the small cyclonic eddy that formed immediately northwest of the Big Island), and (2) a long, narrow “rope cloud” that stretched for a considerable distance across the Pacific Ocean (to the north and northwest of Hawaii), which marked the leading edge of a cold frontal boundary which had become quasi-stationary (large-scale GOES-11 visible image animation).
