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，北半球与南半球（非洲撒哈拉沙漠以南除外）的相似多于相异。

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

北半球处于SOI基本态高代变率，NAOI高基本态代变率的慢变过程下。
