Monthly Highlights on the Climate System

'Monthly Highlights on the Climate System' has been issued in PDF format since March 2007 as a monthly bulletin focusing on the monthly highlights of the monitoring results.

Explanatory Notes

Highlights in September 2016

- The monthly anomaly of the global average surface temperature was the second highest since 1891.
- It is considered that La Niña conditions are present in the equatorial Pacific (see El Niño Outlook updated on 11 October 2016).
- In the lower troposphere, cyclonic and anti-cyclonic circulation anomalies were seen over the southern part of East Asia and the seas southeast of Japan, respectively.
- In the 500-hPa height field, positive height anomalies were seen over Western to Central Siberia, and negative height anomalies were over eastern China.
- Due to typhoons repeatedly approaching or making landfall on Japan and a stationary front near the main island of Japan, monthly sunshine durations were significantly below normal in eastern and western Japan and Okinawa/Amami.
