Abstract | The 1994 floods in Africa, the extreme tropical storm and hurricane season in 1995 and the 1996 flooding in the Pacific Northwest seem to be unrelated events, but are they? Actually all of these events can be linked to oceanic circulation and in particular the conveyor belt theory. This theory states that ocean circulation moves warm and cold water around the globe at different speeds in decadal timescale. The Southern Oscillation Index (SOl) is also influenced by the Conveyor Belt Theory (CBT) .Furthermore, precipitation amounts in the Pacific Northwest correlate with the different phases of the SOl. It appears we are coming out of a long period of weak oceanic circulation and into anew stronger phase. This new phase will likely increase precipitation amounts in the Pacific Northwest. |
