Wyklad 5 Balance of NADW (25)

• Gulf Stream 15 Sv, S 35.88ppm
• Bering Straits 1 Sv, S 32.00ppm
• excess of rainfall and continental runoff
• over evaporation 0.3 Sv
• Balance of NADW 16.35 Sv
• S 34.91ppm

28
Wyklad 5 Thermohaline circulation breakdown
(simulation) (26)

• let an excess of rainfall and continental runoff
  over evaporation 0.45 Sv,
• then water salinity drops to
• S 34.59ppm
• to compensate this drop, deep water
• should to be cooled by 1.4o C and
• to restore a salt balance,
• a circulation has to double its flow !!!
