| Zusammenfassung |
| One of the parts of the Black Sea Nowcasting/Forecasting System is the
regional forecasting system for the easternmost part of the Black Sea
(including the Georgian water area), which has been developed within the
context of the EU International projects ARENA and ECOOP. A core of the
regional system is a high-resolution baroclinic regional model of the Black
Sea dynamics developed at M. Nodia Institute of Geophysics (RM-IG). This
model is nested in the basin-scale model of Marine Hydrophysical Institute
(MHI, Sevastopol/Ukraine). The regional area is limited to the Caucasian and
Turkish coastal lines and the western liquid boundary coinciding with the
meridian 39.36° E. Since June 2010 we have regularly been computing 3
days' forecasts of current, temperature and salinity for the easternmost part
of the Black Sea with 1 km spacing. In this study the results of two
forecasts are presented. The first forecast corresponds to summer season and
covers the prognostic interval from 00:00 h, 6 August to 00:00 h, 9 August
2010. The second one corresponds to autumn season and covers the prognostic
interval from 00:00 h, 26 October to 00:00 h, 29 October 2010. Data needed
for the forecasts – the initial and prognostic hydrophysical fields on the
open boundary, also 2-D prognostic meteorological fields at the sea surface
– wind stress, heat fluxes, evaporation and precipitation rates for our
regional area are being placed on the MHI server every day and we are
available to use these data operatively. Prognostic hydrophysical fields are
results of forecast by the basin-scale model of MHI and 2-D meteorological
boundary fields represent the results of forecast by regional atmospheric
model ALADIN. All these fields are given on the grid of basin-scale model
with 5 km spacing and with one-hour time step frequency for the integration
period. The analysis of predicted fields shows that to use the model with
high resolution is very important factor for identification of nearshore
eddies of small sizes. It should be noted the very different character of
regional circulation in summer and autumn seasons in the easternmost part of
the Black Sea. |
