This special report of the Bulletin of the American Meteorological Society (BAMS) presents some extreme events in 2016, such as the record global heat, the heat across Asia, the 2015-16 El Niño and a marine heat wave off the coast of Alaska, and discusses how human-caused climate change may have affected the strength and likelihood of these extreme events....

On the fragile relationship between El Niño and California rainfall
This study newly accepted in Geophysical Research Letters examined why California experienced extremely wet winter and spring conditions during the 1997-98 and 1982-83 El Niños, but near normal rainfall during the extremely strong 2015-16 El Niño. Statistical data analyses and simple model experiments were used to show that sufficiently warm and persistent sea surface temperature anomalies... Continue Reading →
Interannual variability of western North Pacific SST anomalies and its impact on North Pacific and North America
In this study, the interannual variability of sea surface temperature (SST) and its atmospheric teleconnection over the western North Pacific (WNP) toward the North Pacific/North America during boreal winter are investigated. First, we defined the WNP mode as the first empirical orthogonal function (EOF) mode of SST anomalies over the WNP region (100–165°E, 0–35°N), of... Continue Reading →
