Outline

• Part 1: Coding

• Part 2: MAB EOF for EL and (U,V) current for coarse grid

• Part 3: GOM oscillator analysis: gomn117_noassim_noptb_n?wn_41: 02 to 62

• Part 4: GOM oscillator analysis: gomn117_noassim_noptb_n?wn_nogd_tprni0.05_c10_41

Part 1: coding for MAB

• Coarse grid run1. continue ua*3.0 to year 20082. new one with correct tidal data3. new one with correct tidal data and ccmp3 wind

• Fine grid run1. new one from above 22. new one from above 3

Part 2: MAB EOF (cgrid)• EL, (U, V) current, Period: 1993-2007

ELMode #1

1st mode need to be excluded

ELMode #1

After 1st mode is excluded

Mode #3Mode #2

(UV): surface to 50mMode #1

Comparing to fine grid, mode #1 is similar.

Mode #3Mode #2

Mode #5Mode #4

Part 3: GOM

• gomn117_noassim_noptb_n?wn_41: 02 to 62• Composite for eddy days

• 1998/11 to 2003/11

• No wind (shown last week), with wind
