  1. What spatial patterns exist in Labrador SST anomalies? What about North Atlantic SST anomalies? How much variance of these regions do these EOFs explain? Singular Value DecompositionNorth Atlantic SST Angela Fritz

  2. Labrador Sea SST Combination of SEAFLUX SST and Reynolds SST Originally 3 hourly, averaged into monthly 1988 – 2000 144 time steps 50N – 75N, 70W – 40W Every 0.25 degrees North Atlantic SST Reconstructed global sea surface temperature based on COADS data Monthly Dec 1870 through Feb 2004 402 time steps 0 – 80N, 100W – 0 Every 2 degrees Data Description Angela Fritz

  3. Method • Remove the means in data set • Construct a matrix where each column is a point in the domain and each row in the column is a time step • Remove the columns where there is missing data (NaNs) • Perform the SVD analysis • To remap the EOFs, replace the missing data in the new grids Angela Fritz
