Climatology of geostrophic currents in the Northern Adriatic

Climatology of the geostrophic currents in the northern Adriatic, based on a large amount of historical data, is documented. The geostrophic circula- tion can be resolved into the winter circulation, the summer circulation and transition circulations in spring (April and May) and in autumn (September and October). There is a permanent existence of a local cyclonic gyre in Trieste Bay and a northern Adriatic (NAd) current connected with west- ern-middle Adriatic (W-MAd) current throughout the year. During the win- ter period the circulation in the northern Adriatic is a part of the global Adriatic cyclonic gyre. In the spring starts the meandering of low-salinity water toward the east. This "anticyclonic meander comes to the Istrian coast in August and September in conjunction with the Istrian coastal counter- current (lCCC), suggesting the existence of a sharply defined eastward mov- ing anticyclonic meander from June to September. There is good agreement in August and September between measured residual and calculated baro- clinic currents. The northern Adriatic (NAd) cyclonic gyre is present only in December.
