Data: 200 hPa velocity potential anomaly
(x 10^5 m^2/s) on a 2.5° lat/lon grid
Base Period for Climatology: 1 Jan 2002 to present
Data Source: NCEP/NCAR Reanalysis
Description: Five-day average 200 hPa velocity potential anomalies
for the last 180 days over the equatorial Indian and Pacific Oceans (50°E to 80°W longitude),
averaged over 5°S to
5°N latitude. Shading starts at -/+10 x 10^5 m^2/s. Shading interval is 20 x 10^5 m^2/s. The most recent data are at the top of the figure. The vertical black line denotes 180° longitude.
NCEP is an acronym for the US National Centers
for Environmental Prediction, and NCAR is an acronym for the National Center for Atmospheric Research. |
