These slides show that the late summer/early fall problem with the 850 hPa wind near the Galapagos Islands has existed since Aug. 2000. Aug. 1999 seems different from later years with a smaller error near the Galapagos. Glenn.White@noaa.gov

6hr error in 850 merid wind at the equator as a time series for Aug. 2002, 2003 (previous slide) and 2004
1-day error in 850 meridional wind at the equator for 2001, 2002, 2003, 2004
Time-mean Horizontal divergence as a function of pressure and longitude at 5N during August. Low-level divergent circulation in east Pacific is weaker in 2000, 2001 and 2002 than other years. Is it real or is it model?
6 hr “error” in meridional velocity at the equator as function of pressure and longtiude for August.”Error” is much less in 1999 than later years.
1 and 3 day “error” in meridional velocity at the equator as function of pressure and longtiude for August.1 day ”error” is much less in 1999 than later years. Note 3 day error near 100W is less than 1 day error!
850 6 hr error in winds for August. Error similar in all 4 years.
850 1 day error in winds for August. Error similar in all 4 years.
850 hPa merid wind 6hr rms “error” for August. Largest error in each year near Galapagos.
850 hPa merid wind 1day rms “error” for August. Largest error in each year near Galapagos.
