Sub-Surface Temperature Departures in the Equatorial Pacific Since early November, positive subsurface temperature anomalies have stretched across most of the equatorial Pacific. Most recent pentad analysis During December, positive subsurface anomalies in the east-central Pacific weakened.
Tropical OLR and Wind Anomalies During the Last 30 Days Positive OLR anomalies (suppressed convection and precipitation, red shading) were apparent near the Date Line (centered south of the equator). Negative OLR anomalies (enhanced convection and precipitation) were evident over Indonesia, the Philippines, and northern Australia. Low-level (850-hPa) winds were near-average across most of the equatorial Pacific, while anomalous easterlies were present over the western Pacific. Anomalous upper-level (200-hPa) easterly winds were evident across the eastcentral equatorial Pacific.
