| 1 | Numerical prediction experiment on Typhoon Maggie (9903)显示文摘The movement of Typhoon Maggie (9903) in June 1999 is one of the rare cases ever seen in the history. At 00U on June 6 Maggie was located at about 70 km to the southwest of Taiwan. When it arrived at the coastal region of Shanwei City (22.8N, 116.5E), it turned suddenly to move southwestward along the southern China coastal line. De June 7 Maggie finally turned to move northward, making landfall to the north of Shangchuan Island. The experimental numerical prediction system on typhoon movement that was designed based on MM5 is proved quite successful for the 48h prediction of Maggie’s movement and rainfall. The mean prediction error of typhoon track is 81 km for 0-24 h and 74 km for 24-48 h. The location of typhoon center in the initial field of the model is approximately 100 km away from the actual observations. In order to modify the location of typhoon center, a bogus typhoon was intro- duced into the model and the prediction of typhoon track was improved in 0-24 h time interval. But the prediction error was enlarged in 24-36 h. We also performed a sensitivity experiment of changing the land of southern China into the ocean. It is found that the orientation of South China coastal line and the topography have no obvious effect on the movement of Typhoon Maggie. | Fong Soi Kun, Wu Chisheng, Hao I Pan, Lam Kin Hang Ku Chi Meng, Wang Anyu, Lin Wenshi (1.

| 2 | Gedunin Degrades Aggregates of Mutant Huntingtin Protein and Intranuclear Inclusions via the Proteasomal Pathway in Neurons and Fibroblasts from Patients with Huntington’s Disease显示文摘Huntington's disease(HD) is a deadly neurodegenerative disease with abnormal expansion of CAG repeats in the huntingtin gene. Mutant Huntingtin protein(m HTT) forms abnormal aggregates and intranuclear inclusions in specific neurons, resulting in cell death. Here,we tested the ability of a natural heat-shock protein 90 inhibitor, Gedunin, to degrade transfected m HTT in Neuro-2 a cells and endogenous m HTT aggregates and intranuclear inclusions in both fibroblasts from HD patients and neurons derived from induced pluripotent stem cells from patients. Our data showed that Gedunin treatment degraded transfected m HTT in Neuro-2 a cells, endogenous m HTT aggregates and intranuclear inclusions in fibroblasts from HD patients, and in neurons derived from induced pluripotent stem cells from patients in a dose-and time-dependent manner, and its activity depended on the proteasomal pathway rather than the autophagy route. These findings also showed that although Gedunin degraded abnormal m HTT aggregates and intranuclear inclusions in cells from HD patient, it did not affect normal cells, thus providing a new perspective for using Gedunin to treat HD. | Weiqi Yang Jingmo Xie Qiang Qiang Li Li Xiang Lin Yiqing Ren Wenlei Ren Qiong Liu Guomin Zhou Wenshi Wei Hexige Saiyin Lixiang Ma | 2019 | Neuroscience Bulletin2019，35，6： | 2 |

| 4 | A numerical simulation of latent heating within Typhoon Molave显示文摘The weather research and forecasting(WRF) model is a new generation mesoscale numerical model with a fine grid resolution(2 km), making it ideal to simulate the macro-and micro-physical processes and latent heating within Typhoon Molave(2009). Simulations based on a single-moment, six-class microphysical scheme are shown to be reasonable, following verification of results for the typhoon track, wind intensity, precipitation pattern, as well as inner-core thermodynamic and dynamic structures. After calculating latent heating rate, it is concluded that the total latent heat is mainly derived from condensation below the zero degree isotherm, and from deposition above this isotherm. It is revealed that cloud microphysical processes related to graupel are the most important contributors to the total latent heat. Other important latent heat contributors in the simulated Typhoon Molave are condensation of cloud water, deposition of cloud ice, deposition of snow, initiation of cloud ice crystals, deposition of graupel, accretion of cloud water by graupel, evaporation of cloud water and rainwater,sublimation of snow, sublimation of graupel, melting of graupel, and sublimation of cloud ice. In essence, the simulated latent heat profile is similar to ones recorded by the Tropical Rainfall Measuring Mission, although specific values differ slightly. | LIU Yang LIN Wenshi LI Jiangnan WANG Gang YANG Song FENG Yerong | 2017 | Acta Oceanologica Sinica2017，36，7： | 1 |
| 5 | Sea-Salt Aerosol Effects on the Simulated Microphysics and Precipitation in a Tropical Cyclone显示文摘We investigate the effects of sea-salt aerosol(SSA) activated as cloud condensation nuclei on the microphysical processes, precipitation, and thermodynamics of a tropical cyclone(TC). The Weather Research and Forecasting model coupled with Chemistry(WRF-Chem) was used together with a parameterization of SSA production. Three simulations, with different levels of SSA emission(CTL, LOW, HIGH), were conducted. The simulation results show that SSA contributes to the processes of autoconversion of cloud water and accretion of cloud water by rain,thereby promoting rain formation. The latent heat release increases with SSA emission, slightly increasing horizontal wind speeds of the TC. The presence of SSA also regulates the thermodynamic structure and precipitation of the TC.In the HIGH simulation, higher latent heat release gives rise to stronger updrafts in the TC eyewall area, leading to enhanced precipitation. In the LOW simulation, due to decreased latent heat release, the temperature in the TC eye is lower, enhancing the downdrafts in the region; and because of conservation of mass, updrafts in the eyewall also strengthen slightly; as a result, precipitation in the LOW experiment is a little higher than that in the CTL experiment.Overall, the relationship between the precipitation rate and SSA emission is nonlinear. | Baolin JIANG Wenshi LIN Fangzhou LI Junwen CHEN | 2019 | Journal of Meteorological Research2019，33，1： | 1 |

| 8 | Effects of local and non-local closure PBL schemes on the simulation of Super Typhoon Mangkhut(2018)显示文摘With the convection-permitting simulation of Super Typhoon Mangkhut(2018)with a 3 km resolution for 10.5 days using mesoscale numerical model,Weather Research and Forecasting Model Version 4.1(WRFV4.1),the influences of local closure QNSE planetary boundary layer(PBL)scheme and non-local closure GFS planetary boundary layer scheme on super typhoon Mangkhut are mainly discussed.It is found that in terms of either track or intensity of typhoon,the local closure QNSE scheme is better than the non-local closure GFS scheme.Local and non-local closure PBL schemes have a large influence on both the intensity and the structure of typhoon.The maximum intensity difference of the simulated typhoon is 50 hPa.The intensity of typhoon is closely related to its variations in structure.In the rapid intensification stage,the typhoon simulated by the QNSE scheme has a larger friction velocity,stronger surface latent heat flux,sensible heat flux and vapor flux,related to a higher boundary height and stronger vertical mixing.The latent heat flux and sensible heat flux on the surface conveyed energy upward for the typhoon while the water vapor was transported upward through vertical mixing.While the water vapor condensed,the latent heat was released,which further warmed the typhoon eyewall,strengthening the convection.The stronger winds also intensified the vertical mixing and the warm-core structure,further strengthened the typhoon.The differences in surface layer schemes dominated the differences between the two simulations. | Zixi RUAN Jiangnan LI Fangzhou LI Wenshi LIN | 2022 | Frontiers of Earth Science2022，16，2： | 0 |
| 9 | Daily Changes of Spatial Patterns of Meteorological Elements over Pearl River Delta Based on GIS and MM5显示文摘The spatial distribution of meteorological elements is important for understanding the regional meteorology and climate changes. However,previous studies rarely focused on the daily changes of the spatial patterns of meteorological elements due to the limitation of remote sensing(RS) techniques and traditional meteorological methods. In this paper,the regional meteorological elements were simulated by the fifth-generation non-hydrostatic Mesoscale Model(MM5) ,and the spatial patterns of meteorological elements and their diurnal variations were analyzed in landscape level over the Pearl(Zhujiang) River Delta(PRD) ,China. The results showed that there were several centers of urban heat islands,cold islands,dry islands,wet islands,high wind over the PRD at noon. The diurnal changes of Moran I of meteorological elements were obvious and they reached the extremum at noon and 2-3 hours after the sunrise. The landscape indices of meteorological elements,such as area-weighted mean Fractal Dimension Index(FRAC_AM) ,Landscape Shape Index(LSI) ,Shannon's Diversity Index(SHDI) and Contagion Index(CONTAG) ,were more variable at about the sunrise,noon and sunset. The occurrence of wave crests and vales of landscape indices was affected by the surface net radiation,turbulence and local circumfluence. The spatial patterns of meteorological elements correlated well with the land surface,thermal exchanges and local circumfluence. A new approach combining GIS,RS and numerical simulations technologies and the landscape ecology method was presented to analyze spatial patterns of meteorological elements,which may be useful for studying global and regional climate changes. | JIANG Xueding XIA Beicheng LIN Guangfa LIN Wenshi | 2009 | Chinese Geographical Science2009，19，1： | 0 |
