The spectral and turbulence characteristics of wind are compared with earlier measurements made at a comparatively homogeneous terrain and the standards available in literature. The study show the smaller eddies in the vertical velocity spectrum attains equilibrium with the underlying surface at a short fetch itself and follows spectral similarity. However, this is not followed by longitudinal and transverse velocity spectra under unstable as well as stable conditions.</p>10aheterogeneity10aIBL10asea-land interface10awind spectra1 aMurthy, B., S.1 aLatha, R.1 aSukumaran, Cini1 aShivaji, A.1 aSivaramakrishnan, S.  uhttps://library.ncl.res.in/content/influence-spatial-heterogeneity-internal-boundary-layer-short-fetch-0
