      abstract     = {Previous studies based on satellite observations and model
                      simulations have revealed a significant correlation between
                      intense stratospheric gravity wave (GW) activity and
                      hurricane intensification. This research further
                      investigated the underlying mechanism of this correlation by
                      analyzing the properties and propagation characteristics of
                      stratospheric GWs excited by Hurricane Joaquin based on a
                      Weather Research and Forecasting model simulation. By
                      employing the 3-D Stockwell wave analysis method, we found
                      that GWs excited during hurricane intensification display
                      relatively higher intrinsic frequencies, shorter horizontal
                      wavelengths, and longer vertical wavelengths than during
                      weakening. Analysis of these GWs' propagation using the
                      GROGRAT ray-tracing model revealed that they can reach the
                      middle stratosphere rapidly within 20 min. This quick
                      propagation enabled the observation of intense stratospheric
                      GWs before the hurricane reached its peak intensity,
                      offering a potential indicator for hurricane
                      intensification. These findings strengthened the basis for
                      considering stratospheric GW activity as a proxy for
                      hurricane intensification under specific conditions.},
