SST Regions: NorthEast Pacific 23N-65N, 120E-180E

2011 March 8
Next up is the NorthEast Pacific as defined by a bounding box 23N-65N, 100W-180W. Over the weekend, there were some modifications to my first presentation. Inverted the x-axis on the Fourier chart. Formatted the freq text on Fourier chart. Created a preset color scale for the maps. Colors and cuts from HadSST2 map. I also saved off the ERSST annual raster so that I don’t have to recalculate it for each run.

There were some ‘NA’s in this region for HadSST. Truncating the early span to remove the NAs years reduces the overall length of the record. Also, the world map in the ‘maps’ package run from -180 to 180, while the ERSST latitudes run from -1 to 359. I’ll fix that in a future version.

The very strong signal at 5.5 years found in the NorthWest Pacific is not present in the NorthEast Pacific.
