William

notes: upwelling systems of the world

trying to understand the change in the yearly cycle (and sub yearly)

• More detrend methods
• Make time series plot of intensity of the yearly cycle (1.0) and the 0.25 cycle

next step: trying to understand how the non-year part is changing

• Plot # of months that the upwelling is negative (so no upwelling)
• Plot the detrend line (so the cubic line that fits the data)

work on this area

Anthony

• detrend
• 7-day average
• explain the homonogenization
• paper that mentions the 3 month cycle

Presentation

https://docs.google.com/presentation/d/1Hx7HQYiyQv2HKxqwOVCTKL3bvu55lbJNxJJt2bqDAJE/edit#slide=id.p1

• Show the non-normalized data in slide 2 or 3 before the normalized data
• At end, compare the power lag-1 plots for the different detrend methods
• Closing slide, "Bakun hypothosized that xyz" (column 1). "What I found" (column 2).
  • William, 1985 to 2010, upwelling did weaken close the equator, but after 2010, it strengthened. Yearly cycle also increased after 2010
  • Both William and Anthony, what's happening in terms of the strengths of season cycles is location dependent and there are sharp spatial breaks

Anthony update

• Adding further south on Morroco coast
• Power graph like William's
• Add some more info to the headers on slides
• Add y-axes labels (try to write in plain language)
• Add a brief "take-home message" to key slides
