abstract = {Atmospheric gravity waves (GWs) significantly influence
global circulation. Deep convection, particularly that
associated with typhoons, is believed to be an important
source of gravity waves. Stratospheric gravity waves induced
by Typhoon Mindulle (2004) were detected by the Atmospheric
Infrared Sounder (AIRS). Semicircular GWs with horizontal
wavelengths of 100–400 km were found over Taiwan through
an inspection of AIRS radiances at 4.3 μm. Characteristics
of the stratospheric gravity waves generated by Typhoon
Mindulle were investigated using the Weather Research and
Forecasting (WRF) model. The initial and boundary data were
determined by the high-resolution European Center for
Medium-Range Weather Forecasts reanalysis data. The WRF
simulation reproduces the main features of Typhoon Mindulle
and the significant GWs. The simulated GWs with horizontal
wavelengths of 100–400 km match the AIRS observations:
they propagate upward and eastward, and the westward
components are mostly filtered in the stratosphere. By
comparing the measured waves with a WRF simulation in the
absent of orography (WRF-FLAT), we find that the orographic
gravity waves (OGWs) generated by the flow of Typhoon
Mindulle over the Central Mountain Range (CMR) in Taiwan
account for approximately $50\%$ of the total wave momentum
flux in the troposphere. The dominant orientation of the OGW
wave fronts is parallel to the CMR rideline. When entering
into the stratosphere, OGW propagation is determined by the
position of the typhoon center relative to the CMR.},
