Welcome to Natural Heat Engines blog!

Climate science is a relatively young science thrust in the limelight by global warming arguably while still very much in its infancy. So much so that many of its most fundamental aspects have yet to reach a mature state. […] The main aim of this blog is to try to shed some light on various outstanding issues in the field by tracking down the nature of the difficulties that have prevented the oceanographers and atmospheric scientists from reaching a consensus. To that end, the deciding arguments must ultimately be rooted in first principles. That is, they must follow logically and deductively from clearly stated premises and the full Navier-Stokes equations.

Drake Passage Effect: Thermodynamic or Mechanical?

The Drake passage effect usually refers to the apparent sensitivity of the strength of the Atlantic Meridional Overturning Circulation (AMOC) to changes in the zonal wind stress in the Antarctic Circumpolar Current (ACC) region first reported by Toggweiler and Samuels (1993,1995). Because the effect seems to demonstrate a dependence of the AMOC on mechanical forcing, it has done much to undermine the classical buoyancy-driven view of the AMOC that had prevailed so far.
