| Abstract: | Surface layer meteorological data collected at a coastal site, at Vasco-Da-Gama (15°21′N, 73°51′E, 58.5m MSL) (13–18 July,
2002) with prevailing southwesterly surface winds are analyzed to study the characteristics of internal boundary layer at
a short fetch using an instrumented tower (9 m). 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. |
