The basic structure and cloud features of Typhoon Nida
(2016) are simulated using a new microphysics scheme (Liuma)
within the Weather Research and Forecasting (WRF) model. Typhoon
characteristics simulated with the Liuma microphysics scheme are
compared with observations and those simulated with a commonly-
used microphysics scheme (WSM6). Results show that using
different microphysics schemes does not significantly alter the
track of the typhoon but does significantly affect the intensity
and the cloud structure of the typhoon. Results also show that
the vertical distribution of cloud hydrometeors and the
horizontal distribution of peripheral rainband are affected by
the microphysics scheme. The mixing ratios of rain water and
graupel correlate highly with the vertical velocity component
and equivalent potential temperature at the typhoon eye-wall
region. According to the simulation with WSM 6 scheme, it is
likely that the very low typhoon central pressure results from
the positive feedback between hydrometeors and typhoon
intensity. As the ice-phase hydrometeors are mostly graupel in
the Liuma microphysics scheme, further improvement in this
aspect is required. 相似文献
