While the physiographic details for each island are not discernible in this synoptic view of Maui, Molokai, Lanai, and Kahoolawe, the impact of higher volcanic mountains on rainfall patterns and amounts is apparent. Darker, more heavily vegetated landscapes appear on the windward-facing slopes. The predominate cloud cover pattern is on the northeast-facing, windward slopes for three of the islands. Kahoolawe appears to be in the rain shadow of Maui, and the mountainous relief of Kahoolawe is not sufficient to produce a dramatic orographic effect.
