“…Atmospheric aspects and oceanographic responses to Gonu have been studied by different researchers (Fritz et al [21]; Krishna and Rao [22]; Dibajnia et al [23]; Wang et al [24]; Mashhadi et al [20]). Dibajnia et al [23] used the 3rd generation WAVEWATCH-III wave model to simulate the wave field generated by Gonu in the northern Oman Sea and along the Iranian coasts.…”

The third generation wind-wave model Mike21-SW was used to study spectral characteristics of waves generated by the historical Cyclone Gonu in June 2007 along and off the Iranian coasts on the northern Oman Sea. The model was forced with the cyclone wind field generated using a Holland (1980) model based on cyclone data obtained from the Joint Typhon Warning Center (JTWC). The wave model was calibrated for the northern Oman Sea using bulk and spectral wave data at a station out of the Chabahar Bay. Evolution of directional-frequency spectra during the cyclone was investigated for two locations near the entrance and off the Chabahar Bay. At the offshore station, energy was contributed to the spectrum over an approximately 180 degree directional span that included different local and remotely generated waves. As the cyclone proceeded northwestward, all spectral directions continuously rotated in the clockwise direction at both locations. Frequency spectra at these locations were investigated for four different times corresponding to different locations of Cyclone's eye and were justified using the sea growth parameter of the Joint North Sea Wave Project (JONSWAP) experiment. Using the modified JONSWAP parameters for hurricane conditions resulted in a frequency spectrum consistent with simulation results.

“…The resulting warm waters along tropical and subtropical coasts are a principal source of heat and moisture to the lower atmosphere, affecting cloud processes, precipitation and local winds. They therefore provide moist enthalpy (i.e., latent and sensible heat flux) to the boundary layer which may, for example, intensify tropical cyclones [ Krishna and Rao , 2009]. Quantification of surface layer turbulent fluxes over reefs is therefore important for establishing the correct lower boundary conditions in atmospheric global circulation and regional forecasting models so that more accurate predictions of weather are available for marine and coastal locations.…”

Measurements of the local energy balance over a coral reef flat, Heron Island, southern Great Barrier Reef, Australia

[1] Coral reefs are thought to face significant threat from global warming due to increased water temperatures and ocean acidity. However, research into the surface energy balance of coral reefs and their associated micrometeorology is rare. Here we present, through a case study approach, the first direct in situ measurements of the surface energy balance of Heron Reef, a small platform coral reef in the southern Great Barrier Reef, Australia. Surface energy exchanges were measured using the eddy covariance method and show that during winter and spring an estimated 80-98% of net radiation goes into heating of the water overlaying the reef and reef substrate. As a result, cloud cover is considered the dominant control on heating of the reef flat environment. Change in cloud cover may therefore significantly affect the thermal environment of coral reefs and their ecology. Sensible and latent heat fluxes reached their highest values during wintertime advection of dry and cool continental air blowing from mainland Australia. This resulted in a net loss of energy from the reef flat and a decreasing trend in water temperature. Turbulent fluxes otherwise remained small, with sensible heat flux often close to zero. Results indicate that coral reefs may act as heat sinks during winter and as heat sources during spring, thereby affecting local water and atmosphere heat budgets and associated thermodynamics.
