Abstract:
This talk is divided into two parts. In part one, we present a statistical model for 1 year predictions of the Gulf Stream path (represented by the Gulf Stream northern wall—GSNW) between 75W and 65W incorporating both wind and buoyancy forcing in a combined framework. In addition, a forecast of the GSNW in 2022 will be presented. In part two, we will examine the Warm Core Ring (WCR) behavior in the Slope Sea focusing on ring movement, vertical structure, and formation processes. Through this work we have found a WCR mean path that shows a very narrow band that rings follow to the west of 65W, this is what we have named the Ring Corridor. Additionally, we have found different patterns in WCR movement speed between long (lifetimes > 150 days) and short (lifetimes < 150 days) lived rings. When analyzing the WCRs vertical structures a trend emerged where rings that are formed further to the west have shallower thermoclines. This trend will be explained through different formation processes along the GS, and a potential formation mechanism will be presented.
