| 1 | 近十年我国热带气旋灾害的特征研究显示文摘利用最新搜集的2004—2013年热带气旋(TC)灾情资料,研究在影响我国TC的特征发生了较大变化的背景下TC灾害的时空分布特征。2004—2013年,TC灾害造成我国的直接经济损失占国民生产总值(GDP)百分比、农作物受灾面积、死亡人口、受灾人口和倒塌房屋数量均比上个十年(1994—2003年)显著减少。我国致灾TC年频数整体呈增加态势,但其造成的直接经济损失、农作物受灾面积和受灾人口均表现为先增加后减少再增加的变化特征,死亡人口和倒塌房屋数量表现为先增加后减少的变化特征。我国TC灾害造成的各项损失总量与TC灾害发生频次的空间分布较一致。从平均单次损失来看,我国北方和内陆的部分地区由TC灾害造成的直接经济损失、农作物受灾面积和受灾人口较严重。 | 赵珊珊 任福民 高歌 黄大鹏 | 2015 | 热带气象学报2015，31，3： | 31 |
| 2 | A simplified index to assess the combined impact of tropical cyclone precipitation and wind on China显示文摘Relationships between tropical cyclone(TC)precipitation,wind,and storm damage are analyzed for China based on TCs over the period from 1984 to 2013.The analysis shows that the maximum daily areal precipitation from stations with daily precipitation of ≥50 mm and the sum of wind gusts of ≥13.9 m/s can be used to estimate the main damage caused by TCs,and an index combining the precipitation and wind gust of a TC(IPWT)is defined to assess the severity of the combined impact of precipitation and wind.The correlation coefficient between IPWT and the damage index for affecting TCs is 0.80,which is higher than that for only precipitation or wind.All TCs with precipitation and wind affecting China are divided intofive categories,Category 0 to Category 4,based on IPWT,where higher categories refer to higher combined impacts of precipitation and wind.The combined impact category is closely related to damage category and it can be used to estimate the potential damage category in operational work.There are 87.7%,72.9%,69.8%,and 73.4%of cases that have the same or one category difference between damage category and combined impact category for Categories 1,2,3,and 4,respectively.IPWT and its classification can be used to assess the severity of the TC impact and of combined precipitation and wind conveniently and accurately,and the potential damage caused by TCs.The result will be a good supplementary data for TC intensity,precipitation,wind,and damage.In addition,IPWT can be used as an index to judge the reliability of damage data.Further analysis of the annual frequency of combined precipitation-wind impact categories reveals no significant increasing or decreasing trend in impact over China over the past 30 years. | Peiyan CHEN Hui YU Ming XU Xiaotu LEI Feng ZENG | 2019 | Frontiers of Earth Science2019，13，4： | 9 |
| 3 | A Potential Risk Index Dataset for Landfalling Tropical Cyclones over the Chinese Mainland(PRITC dataset V1.0)显示文摘A dataset entitled“A potential risk index dataset for landfalling tropical cyclones over the Chinese mainland”(PRITC dataset V1.0)is described in this paper,as are some basic statistical analyses.Estimating the severity of the impacts of tropical cyclones(TCs)that make landfall on the Chinese mainland based on observations from 1401 meteorological stations was proposed in a previous study,including an index combining TC-induced precipitation and wind(IPWT)and further information,such as the corresponding category level(CAT_IPWT),an index of TC-induced wind(IWT),and an index of TC-induced precipitation(IPT).The current version of the dataset includes TCs that made landfall from 1949-2018;the dataset will be extended each year.Long-term trend analyses demonstrate that the severity of the TC impacts on the Chinese mainland have increased,as embodied by the annual mean IPWT values,and increases in TC-induced precipitation are the main contributor to this increase.TC Winnie(1997)and TC Bilis(2006)were the two TCs with the highest IPWT and IPT values,respectively.The PRITC V1.0 dataset was developed based on the China Meteorological Administration’s tropical cyclone database and can serve as a bridge between TC hazards and their social and economic impacts. | Peiyan CHEN Hui YU Kevin K.W.CHEUNG Jiajie XIN Yi LU | 2021 | Advances in Atmospheric Sciences2021，38，10： | 2 |
| 4 | Infrared Radiance Simulation and Application under Cloudy Sky Conditions Based on HIRTM显示文摘An algorithm based on hyperspectral infrared cloudy radiative transfer model (HIRTM) is introduced and a simulation method for infrared image of the generation geostationary meteorological satellite is proposed. Based on the parameters from weather research and forecast (WRF), such as the water content, atmospheric temperature, and humidity profile, the simulation data for the advanced Himawari imager (AHI) infrared radiative (IR) channels of Himawari-8 are obtained. Simulated results based on HIRTM agree well with the observed data. Further, the movement, development, and change of the cloud are well predicated. And the simulation of IR cloud image for the weather forecast has been obtained. This paper provides an improved method for evaluation and improvement of regional numerical model for weather forecast. | Jian-Hua Qu Jun-Jie Yan Mao-Nong Ran | 2019 | Journal of Electronic Science and Technology2019，17，2： | 0 |
