The 'gradient ascent' method applied to a function. This image shows the surface of the function (3D interpretation). See also: image:gradient ascent (contour)...
(barbs, kt), 800–400 hPa layer-averaged ascent (red contours every 2 m s-1, starting at 0.5 m s-1), SLP (black contours every 4 hPa), total precipitable water...
