  1. Data: No gd, c1=0, NoWind. The same data set as LC cycle paper. Transport integrates at Florida Strait from surface to bottom. Green lines are eddy shedding events. From this plot, the minimum transport leads eddy shedding.

  2. upper:0~200m lower:200~bottom The upper layer transport has similar signal as total transport, but it has more fluctuation. The lower layer is not as clear as the upper one.

  3. Florida Strait transport with deep Yucatan Transport Florida & Yucatan Deep I put those together in order to show the interaction between eddy shedding, Yucatan deep flow and Florida transport. Black contour is Florida transport corresponding to left axis, and red dash curve is Yucatan deep flow respecting to right axis.

  4. Discussion The Yucatan deep flow reaches its minimum after eddy shedding. The eddy propagates westward causing the compensating eastward return deep flow. The return flow is the main source of Yucatan deep flow in this stage. The minimum of Florida transport appears before eddy shedding. It goes back to normal state after eddy shedding. When the LC eddy grows large enough (in stage B, before eddy shedding), the Florida transport starts to drop. This is connected to the Yucatan inflow (upper layer) and the interaction of LC cycle. See next page

  5. The Yucatan inflow reaches its minimum also before eddy shedding (black). The LC eddy moves north and westward with its growing. The shifted LC eddy leaves the large space generating the deep convergence before eddy shedding (stage B). For the mass conservation, the weak deep outflow of Yucatan must come with weaker inflow of Yucatan upper transport (see figure above).

  6. Florida & Yucatan Up After eddy shedding, the strong Yucatan deep outflow is induced by the compensating return flow of westward propagating eddy. The Yucatan upper transport increase also. Therefore, the Florida transport increase (goes back to normal state) after eddy shedding. But the Florida transport (0~bot) and Yucatan upper transport (0~1000m) are not correlated all the time. Because the Florida transport is decided by the upper and lower layer of Yucatan transport. In the other word, only when the lower layer of Yucatan flow is quiet, the upper Yucatan transport is correllated with Florida transport well.
