Meteorological forcing of the Adriatic: present vs. projected climate conditions

Meteorological forcing of the Adriatic is examined under the present and predicted climate conditions. Fields from the time slice-experiment performed with ECHAM4 model (W. May and E. Roeckner: A time-slice experiment with the ECHAM4 AGCM at high resolution - the impact of horizontal resolution on annual mean climate change, Climate Dynamics, 17, 2001, 407-420) are closely analysed for the Adriatic region. Results obtained for the control period, when compared to a number of data, are found to reproduce the main features of the present-day surface heat flux, water flux and wind field above the Adriatic. In the future, the Adriatic should experience a reduction of heat loss to the atmosphere as well as an enhanced evaporation accompanied with a reduced precipitation leading to an overall increase of fresh-water loss to the atmosphere. The changes in synoptic activity should lead to an abatement of bora winds and to a reduced frequency of sirocco events which, however, are expected to be much more persistent. Finally, changes in the dynamics of the Adriatic, induced by altered meteorological forcing, are briefly discussed.
