SST Regions: Tropical West Pacific, 23N-23S, 120E-180E

Next up is the Tropical West Pacific as defined by a bounding box 23N-23S, 120E-180E. There are some issues cropping HadSST2. I noticed it in the NW Pacific as well, but thought it was related to the fact that what should have been the upper row was all ‘NA.’ Gonna have to crack the raster ‘crop’ code open. However, I doubt that a row more or less on the boundaries will materially affect the results.

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

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.

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

I extend the previous work on global and hemispheric fourier analysis with HadSST2 and ERSSTv3b into regional analysis. First up is the NorthWest Pacific as defined by a bounding box 23N-65N, 120E-180E.

HadSST2: Frequencies in Monthly Data

Forgot to update the Fourier and Morlet Wavelets charts in the previous post with monthly data. So here they are. Large charts ahead.

HadSSTv2: Global, NH, SH Frequency Analysis

This is a mash-up of some of my previous work with Fourier and Morlet analysis extended to a globally gridded data set for sea surface temperatures, the Hadley SSTv2, available as a NetCDF file here. I used this in a ‘trb‘ script last fall. My current attempt is a lot cleaner. I must be learning something. The gridding and masking techniques here are a precursor to more regional studies.

Lines, Sines, and Curve Fittings 17 – More Morlets

I combine my Hemispheric Land-Ocean Fourier hacks with the previous Morlet Wavelet imagery.

Natural Variability 1 – One World, Two Cuts

This is a sparse post. It just a test spin on my way to looking for regional trends. Lots of tables, little code.
