![]() ![]() MATER 4 alongstream momentum balance: (a) “kinetic energy” K (dotted line) Bernoulli suction B (dashed line), and potential energy (dot–dashed line). (b) Alongstream derivative terms (continuous line) and their resultant, namely the stress terms (dotted line), as in (19) MATER 2 data (a) components of Tables 3 and 4 bottom stress KU 2 (dashed line), LIW–EMDW entrainment stress (dot–dashed line), MAW–LIW entrainment stress E′ A −1 2 A( V 2 − V 1) 2 (dotted line), and resulting total stress (continuous line). Experimental data of both MATER 2 and MATER 4 have been used ( Tables 3 and 4) (b) Alongstream derivative of the previous termsīivariate linear regression between the alongstream derivative terms and stress terms of (19), assuming E* = 10 −4: we finally obtain E′ = 3.2 × 10 −2 and K = 2.6 × 10 −2. MATER 2 alongstream momentum balance: (a) “kinetic energy” K (dotted line), Bernoulli suction B (dashed line), and potential energy (dot–dashed line). Roman numerals indicate the section numbers for the (a) MATER 2 cruise and (b) MATER 4 cruise (b) Coordinate system of the model the symbols are as explained in the textĮvolution of vein flux from the eastern sill toward the Tyrrhenian Sea: comparison between the model results (dashed line) and in situ data (continuous line). In this sketch γ 1 > 0, γ 2 < 0, and γ 3 < 0 to simulate the situation described in the text. ![]() The layer boundaries are at z = H 1 + h 1 = H 1 + γ 1 y for H i = const, z = H 2 + h 2 = H 2 + γ 2 y, and z = H 3 + h 3 = H 3 + γ 3 y. (a) Schematic representation of the three-layer geostrophic situation. This trajectory corresponds to the centerline of the vein in the different hydrographic sections Schematic route of the vein from the eastern boundary of the strait to the Tyrrhenian Sea. 2 but for MATER 2 cruise (Jan 1997)Īs in Fig. 2 but for MATER 1 cruise (16 Sep–)Īs in Fig. θ– S diagram (b) of EMDW hydrographic characteristics, close to the bottomĪs in Fig. The view of these sections is from the eastern toward the western basin: Sicily is always on the right-hand side. Note in addition that section IV has two passages, but only the western passage is connected with the EMDW passage of section V. PRIMO 93 cruise (Nov 1993) isopycnal cross-sections: (a) in each section interfaces between surface (MAW), intermediate (LIW), and deep (EMDW) layers are indicated. Dots represent the locations of the hydrographic stations (sections indicated by roman numerals) triangles indicate current meter positions ![]()
