Abstract. Mean Dynamic Topography (MDT) is a crucial parameter for estimating dynamic topography, and, therefore, geostrophic circulation from satellite altimetry measurements. In this work we use drifting buoy measurements, hydrographic profiles and along-track Sea Level Anomalies (SLA) to reconstruct MDT of the Black Sea by the "synthetic" method. Obtained MDT shows a lot of mesoscale features, which are not present in previous MDT fields of the Black Sea, mostly based on climatic data. Moreover, gradients of sea level in the synthetic MDT are significantly higher compared to other fields, which is evidence of more intense currents in the basin. Validation of determined MDT field with independent dynamic heights and drifter buoy velocities shows good quantitative and qualitative coincidence over all Black Sea basin and improvements compare to previous fields. New Black Sea MDT will improve quality of altimetry-derived geostrophic velocities and lead to better understanding of the spatial and temporal features of the upper layer dynamics.

e article is devoted to the reconstruction of the fragment of K. Paustovsky’s coloristic picture of the world on the basis of the story “The Black Sea”. The color range used by the writer to create a color continuum is revealed. The color spectrum is presented as a field structure with 4 zones, the zoning is based on quantitative and qualitative characteristic and demonstrates the uniqueness of the writer's idiostyle: starting from the area around field core, the informative component of color term gives way to the figurative one; the connection of color and light is indissoluble; the color terms functionality, which is primarily oriented towards the visualization of space, time and a person in them, reveals the dialectical interrelation of color, light, space and time. The color spectrum dominants (black, white, red). They reflect the individual author's color preferences: the dominance of black; the constant opposition black – white, indicating the writer's romantic worldview; and the standard of Russian color language perception. Based on spatial and color nominations combination, the coloristic space of the story is reconstructed. It is represented with spaces: archaeological, “world of things”, military, air navigation, city and house spaces, sea navigation, necropolis space, natural, creative, man spaces. The dominants are the space of nature, man, sea navigation. The specificity of time coloristic visualization, which in many cases becomes possible due to the spatial and temporal coordinates intersection, is identified. Thus, the dialectical interrelation of color, space and time in the story – its color chronotope – is manifested.
