| 1 | SENSITIVITY OF HURRICANE INTENSITY AND STRUCTURE TO TWO TYPES OF PLANETARY BOUNDARY LAYER PARAMETERIZATION SCHEMES IN IDEALIZED HWRF SIMULATIONS显示文摘This paper investigates the sensitivity of simulated hurricane intensity and structure to two planetary boundary layer(PBL) schemes in the Hurricane Weather and Research Forecast model including 1) the GFS scheme(control run) that uses the K-profile method to parameterize turbulent fluxes, and 2) the MYJ scheme that is based on turbulent kinetic energy(TKE) budget for turbulent closure. Idealized simulations with these two PBL schemes show that the storm in the TKE run is stronger than that in the control run after three days into simulation. Multi-scale structures are evaluated and compared between the control and the TKE runs prior to the divergence of the model-simulated intensity to elucidate the mechanism underlying such a difference in the intensity between the two runs. It is found that the storm in the TKE run has i) a shallower boundary layer with a stronger PBL inflow, ii) stronger boundary layer convergence closer to the storm center, iii) higher vorticity and inertial stability inside the RMW; iv) stronger and deeper updrafts in regions further inward from the radius of maximum wind(RMW), and v) more convective bursts located near the RMW as compared to the control run. Angular momentum budget analysis suggests that the convergence of angular momentum in the boundary layer is much stronger in the TKE run than in the control run, which is responsible for faster spin-up of the hurricane vortex in the TKE run. | JIE TANG JUN A.ZHANG CHANH KIEU FRANK D.MARKS | 2018 | Tropical Cyclone Research and Review2018，7，4： | 5 |
| 2 | REAL-TIME FORECASTS OF TYPHOON RAPID INTENSIFICATION IN THE NORTH WESTERN PACIFIC BASIN WITH THE NCEP OPERATIONAL HWRF MODEL显示文摘This study presents the real-time performance of the United States(US) National Centers for Environmental Prediction(NCEP) operational Hurricane Weather Research and Forecast(HWRF) model in predicting rapid intensification(RI) of typhoons in the North Western Pacific(WPAC) basin in 2013. Examination of all RI cases in WPAC during 2013 shows that the HWRF model captures a consistent vortex structure at the onset of all RI as seen in previous idealized studies with HWRF. However, HWRF has issues with predicting RI when the model vortex is initialized with intensity greater than hurricane strength. Further verification of the probability of detection(POD) and the false alarm rate(FAR) of RI forecasts shows that the HWRF model outperforms all other models used by the US Navy’s Joint Typhoon Warning Center, possessing highest POD and lowest FAR in 2013. Examination of the intensity change forecasts at different forecast lead times also confirms that the HWRF model has superior performance, particularly at the 72-h lead time with the POD index ~0.91 and the FAR index ~0.33. Such unique performance of the HWRF model demonstrates its role in helping operational agencies improve their official intensity(and RI) forecasts for tropical cyclones in the WPAC basin. | VIJAY TALLAPRAGADA CHANH KIEU | 2014 | Tropical Cyclone Research and Review2014，3，2： | 2 |
