In the second quarter the SPCZ was displaced to the northeast.
The extent of suppressed rainfall in the southwest Pacific expanded over the third quarter (July-September) to include most of PNG and most of the islands southwest of the SPCZ.
14 shows that the ITCZ and SPCZ locations and intensities during 2014 matched up well with what might be expected in ENSO-neutral seasons (shown here for the January-March quarter and 180[degrees]-150[degrees]W sector).
In the Southern Hemisphere, the SPCZ was much more intense than normal in the first quarter of 2014 as reported in the Island Climate Update (www.
