A robust relation was found between the RWB frequency and Atlantic tropical cyclone activity during 1979-2012 using the ERA-Interim reanalysis and IBTrACS data. Frequent RWB over the North Atlantic leads to a significant reduction in the column water vapor and an increase in the vertical wind shear over the Atlantic MDR, and thus a decrease in the basin-wide hurricane count and accumulated cyclone energy. The correlation between the RWB frequency and Atlantic hurricane count is comparable to the correlation of Atlantic hurricane count with the MDR relative SST, and higher than that with the Niņo 3.4 index. It was also found that the impacts of RWB over the East Atlantic differ from those over the West Atlantic. The linkages of RWB with different climate factors and the implication for the predictability of RWB will also be briefly discussed.
