| 摘 要： | Having analyzed a global grid temperature anomaly data set and some sea level pressure data during the last century, we found the following facts. Firstly, the annual temperature change with a warming trend of about 0.6℃/100 years in the tropical area over Indian to the western Pacific Oceans was most closely correlated to the global mean change. Therefore, the temperature change in this area might serve as an indicator of global mean change at annual and longer time scales. Secondly, a cooling of about -0.3℃ / 100 years occurred over the northern Atlantic. Thirdly, a two-wave pattern of temperature change, warming over northern Asia and northwestern America and cooling over the northern Atlantic and the northern Pacific, occurred during the last half century linked to strengthening westerlies over the northern Atlantic and the weakening Siberian High. Fourthly, a remarkable seasonal difference occurred over the Eurasian continent, with cooling (warming) in winter (summer) during 1896-1945, and warming (cooling) in winter (summer) during 1946-1995. The corresponding variations of the North Atlantic Oscillation and the Southern Oscillation were also discussed.

| Abstract: | Having analyzed a global grid temperature anomaly data set and some sea level pressure data during the last century, we found
the following facts. Firstly, the annual temperature change with a warming trend of about 0.6°C/ 100 years in the tropical
area over Indian to the western Pacific Oceans was most closely correlated to the global mean change. Therefore, the temperature
change in this area might serve as an indi-cator of global mean change at annual and longer time scales. Secondly, a cooling
of about -0.3°C/ 100 years occurred over the northern Atlantic. Thirdly, a two-wave pattern of temperature change, warming
over northern Asia and northwestern America and cooling over the northern Atlantic and the northern Pa-cific, occurred during
the last half century linked to strengthening westerlies over the northern Atlantic and the weakening Siberian High. Fourthly,
a remarkable seasonal difference occurred over the Eurasian con-tinent, with cooling (warming) in winter (summer) during 1896–1945,
and warming (cooling) in winter (summer) during 1946-1995. The corresponding variations of the North Atlantic Oscillation
and the South-ern Oscillation were also discussed.
