Fig. 4: The climate zones composite lakes hypsography.
From: A comprehensive framework for integrating lake hypsography and function on a global scale
The 3D circular representation was created by revolving the area at depth profile (as circular cross-sections, with radius = √area, scaled to km) around the vertical depth axis of the composite lakes of the main climate zones (left panel maps) based on the present Köppen–Geiger climate classification39. a–e, The sub-climate zones were aggregated to reflect the Cold (a), Tropical (b), Temperate (c), Polar (d) and Arid (e) climates. The composite lakes scale is absolute in km. The dark grey on the global maps represents the area of the climate zone coverage39. The 2D graphs show the equivalent hypsographic curve with relative depth (x axis) and relative area at depth (y axis) on a 1:1 scale.
