北半球

Healthwise, the Northern Hemisphere and the Southern Hemisphere outside of sub-Saharan Africa are more alike than different.

以健康问题而言，北半与南半（撒哈拉沙漠以南除外）相似点多于相异点。

Recently northern global climate was controlled by high (low) base state, low (high) decadal and interannual variability of SOI(NAOI).

近期北半处于SOI基本态高年际及年代际率，NAOI高基本态年际及年代际率过程下。
