The 2015/16 El Niño is compared with the two previous strongest events, the 1982/83 and 1997/98 El Niño. The 2015/16 winter features a basin warming in the Indian Ocean, a negative sea surface temperature (SST) anomaly shifted to the north in the western Pacific Ocean in addition to a positive SST anomaly shifted to the west in the eastern Pacific Ocean. These SST distributions lead to suppressed convection in the Maritime Continent, and to a weakened Hadley circulation in the western Pacific Ocean. The eastern Asian monsoon in the 2015/16 winter was also weakened due to the dominance of the western Pacific (WP) pattern. On the other hand, the third and fourth centers of action of Pacific/North American (PNA) pattern in the 2015/16 case are obscure. This may be due to weak divergence in the eastern Pacific Ocean.

La Niña cases that occurred after 1948 are classified into cold and non-cold winters in the Far East to investigate the formation of disparate teleconnection patterns corresponding to the two types and to compare with those during El Niño. According to composite analyses using reanalysis datasets, the North Pacific Oscillation (NPO)/western Pacific (WP) pattern (NPO/WP pattern) and the Pacific-North American (PNA) pattern dominate in the cold and non-cold winters, respectively. As during El Niño, modulations of the local Hadley circulation associated with La Niña play an important role in the formation of the teleconnection patterns. These results indicate that the formation mechanisms of teleconnection patterns during La Niña are the same as those during El Niño but are not simple reverse signals.

耳で聞いた和音の協和, 不協和につき, 単振動を発する発振器により種々組合せた波形の相違を見る場合, 音程が近いものと広いものとは波形の相違が明らかに見られるが, 極めて接近した2種の音程については波形の相違を見分けることは極めて困難である。波形から見れば全音や半音は明らかに唸りを生じ三度の音程も細い唸りが見られるが, 四度五度の音程は唸りの感じが非常に少くなり, 六度の音程は多少動揺的で七度の音程は動揺的不安定である。
