| 1 | Sensitivity of the Simulation of Tropical Cyclone Size to Microphysics Schemes显示文摘The sensitivity of the simulation of tropical cyclone(TC) size to microphysics schemes is studied using the Advanced Hurricane Weather Research and Forecasting Model(WRF). Six TCs during the 2013 western North Pacific typhoon season and three mainstream microphysics schemes–Ferrier(FER), WRF Single-Moment 5-class(WSM5) and WRF Single-Moment6-class(WSM6)–are investigated. The results consistently show that the simulated TC track is not sensitive to the choice of microphysics scheme in the early simulation, especially in the open ocean. However, the sensitivity is much greater for TC intensity and inner-core size. The TC intensity and size simulated using the WSM5 and WSM6 schemes are respectively higher and larger than those using the FER scheme in general, which likely results from more diabatic heating being generated outside the eyewall in rainbands. More diabatic heating in rainbands gives higher inflow in the lower troposphere and higher outflow in the upper troposphere, with higher upward motion outside the eyewall. The lower-tropospheric inflow would transport absolute angular momentum inward to spin up tangential wind predominantly near the eyewall, leading to the increment in TC intensity and size(the inner-core size, especially). In addition, the inclusion of graupel microphysics processes(as in WSM6) may not have a significant impact on the simulation of TC track, intensity and size. | Kelvin T.F.CHAN Johnny C.L.CHAN | 2016 | Advances in Atmospheric Sciences2016，33，9： | 4 |

| 4 | Recent progress in research and forecasting of tropical cyclone outer size显示文摘This review article summarizes the current understanding and recent updates to tropical cyclone outer size and structure forecasting and research primarily since 2018 as part of the World Meteorological Organization's 10th International Workshop on Tropical Cyclones.A more complete understanding of tropical cyclone outer wind and precipitation is key to anticipating storm intensification and the scale and magnitude of landfalling hazards.We first discuss the relevance of tropical cyclone outer size and structure,improvements in our understanding of its life cycle and inter-basin variability,and the processes that impact outer size changes.We next focus on current forecasting practices and differences among warning centers,recent advances in operational forecasting,and new observations of the storm outer wind field.We also summarize recent research on projected tropical cyclone outer size and structure changes by the late 21st century.Finally,we discuss recommendations for the future of tropical cyclone outer size forecasting and research. | Benjamin A.Schenkel Chris Noble Daniel Chavas Kelvin T.F.Chan Stephen J.Barlow Amit Singh Kate Musgrave | 2023 | Tropical Cyclone Research and Review2023，12，3： | 0 |
