Abstract:

This talk will introduce the book “Climate Variability and Tropical Cyclone Activity” that I coauthored with Dr. Hiroyuki Murakami of NOAA/Geophysical Fluid Dynamics Laboratory, published recently by Cambridge University Press (May 2022). This book has seven chapters and is organized as follows: introduction in Chapter 1; description of the intraseasonal oscillation in Chapter 2; interannual to interdecadal variability in Chapter 3; modulation of tropical cyclone (TC) activity by various climate modes in each ocean basin in Chapter 4; discussion on the subseasonal to seasonal TC prediction in Chapter 5; typhoon rainfall variations under changing climate in Chapter 6; followed by Chapter 7 for future TC projections. Apart from some tropical atmosphere-ocean feedbacks on climate time scales, major climate modes that modulate TC activity such as the Madden-Julian Oscillation, Quasi-biweekly Oscillation, Eastern Pacific El Niño, central Pacific El Niño, North Atlantic Oscillation, Pacific Meridional Mode, Atlantic Meridional Mode, and Atlantic Multidecadal Oscillations are described. TC activity includes genesis location, frequency of storm occurrence, life span, tracks, landfall rates, and/or storm intensity. The ocean basins include the western North Pacific and the South China Sea, eastern and central North Pacific, South Pacific, and North Atlantic. Because reliable TC records for the Indian Ocean are relatively short, TC activity in the Indian Ocean is excluded.
