Scientists Find Western Pacific Cyclone Genesis HAS DECREASED Since 1977!
By P Gosselin on 21. October 2018
A new paper authored by Hu et al appearing in the journal Dynamics of Atmospheres and Oceans finds that tropical cyclone (TC) genesis frequency in the western North Pacific (WNP) during 1960–2014 shows a step-by-step decrease and is linked to natural oceanic cycles, namely to the phase of the Interdecadal Pacific Oscillation (IPO).
Sea surface temperature “cannot explainâ€
The authors found that vertical wind shear especially the zonal wind shear plays a critical role, while other parameters such as sea surface temperature (SST), vertical velocity, divergence, humidity and maximum potential intensity cannot explain the step-by-step decrease of tropical cyclone genesis frequency.
