“…In the last two decades occurrence of the large barotropic inflows was lower, while weak and moderate inflows were more often (Meier, 2006). The last two inflows in 1993 and 2003 were well-studied phenomena by observation (inflow in 1993(inflow in : Jakobsen, 1995Matthäus and Lass, 1995;inflow in 2003inflow in : Feistel et al, 2004Piechura and Beszczyńska-Möller, 2004) and by hydrodynamic Q6 modelling (inflow in 1993(inflow in : Andrejev et al, 2002Huber et al, 1994;Lehmann 1995;Meier and Doscher, 2003;inflow in 2003inflow in : Lehmann et al, 2004Meier et al, 2004). The medium size (ca 200 km 3 ) inflow in 2003 with extremely low temperature (ca 1-28C) reached all basins in the Baltic Proper (Feistel et al, 2004).…”
