The paper studies the spectral characteristics of the coastal wind field variability near the South coast of Crimea in the zone of horizontal inhomogeneities of the land surface underlying the atmosphere and sea to specify the role of the coastal wind variability in the formation of coastal water circulation features. Reliable knowledge of these features is necessary for ecological standardization of the anthropogenic impact on marine ecosystems as part of ecological and economic processes management in the coastal sea zone. Archived data were used from standard meteorological observations of wind variability over a 10-year period of instrumental monitoring (1997-2006) at the Black Sea hydrophysical sub-satellite testing area of Marine Hydrophysical Institute near Cape Kikineiz onshore and offshore and at the hydrometeorological station near Cape Nikita (Yalta). The advanced information technology of processing and quality control of vector data was used to ensure the unity of multi-year measurements, which allowed increasing the accuracy of measured wind characteristics. The peculiarities of spectral characteristics of the coastal wind field variability in daily, mesoscale and seasonal ranges were found out. The obtained in situ results were compared with the known results of numerical modelling using modern models of regional atmospheric circulation with high spatial and temporal resolution. The scientific novelty of the work is in obtaining representative empirical knowledge during the analysis of materials on the peculiarities of wind condition variability near the coast in zones with horizontal heterogeneities of the properties of the land surface underlying the atmosphere and comparing these results with the existing model developments. Such integrated studies provide reliable knowledge of the circulation patterns of coastal waters off the South coast of Crimea given the effects of local winds.
