37. A geometric ray has a phase kz z, where z is the depth of the ray. The WKB approximation of a normal mode depth function has a phase ± ∞ z′ z kz (z, km) dz for upward and downward traveling waves where kz = k2 (z) - km2; z′ is a constant. See, for example, L. Tolstoy, " The W.K.W. Approximation, turning points and the measurement of phase velocities.," J. Acoust. Soc. Am. 52, 356-363 (1972). Hence for the path integral, ei kz z is replaced by the mode depth function, and for the second moment, one inserts the mode depth-function squared, integrated over depth.
