ebtrk_atlc_1988_2015.txt is the EBTRK version uploaded on July 27, 2016, see https://rammb2.cira.colostate.edu/research/tropical-cyclones/tc_extended_best_track_dataset/ Lines from 03437 till 11824 correspond to storms in 1998-2015, a total of 8387 records. pre-wv-new-2023.zip contains 2x8387 files with TRMM precipitation distributions for those 8387 records. For example, file pre-wv-new-04568.txt is for AL1200 HELENE 15 September 18:00 2000 from EBTRK. The file contains 70 lines corresponding to distance r_i =i*25 km from the storm center, where i is the line number, 25 km <= r_i <= 3000 km. Numbers in the first column are the local TRMM precipitation (mm/hour) averaged among the TRMM cells that are no more than r_i but not less than r_(i-1) km (r_0 =0) from the storm center. Missing data correspond to -1. The number of TRMM cells for which precipitation is averaged is given in the 5th column. For this record (no. 4568), number 1.672 in the first column, fifth row indicates that the mean 3-hour TRMM precipitation between 100 km and 125 km from the storm center was 1.672 mm/hour, with 26 cells used to calculate this average. (The remaining columns are not relevant for this study but were used by Makarieva et al. 2017 https://doi.org/10.1016/j.atmosres.2017.04.006. The 2nd column gives the mean TRMM precipitation (mm/hour) in the absence of storms, 3rd column is the mean MERRA water vapor content (mm), 4nd column is the mean MERRA water vapor content (mm) in the absence of storms, 6th column is the number of MERRA cells used to calculate water vapor content, 7th column is r_i (km).) File pre-wv-int-new-04568.txt has the same structure, but it reports the mean TRMM precipitation (mm/hour) within the circle of radius r_i. For this record (no. 4568), number 1.899 in the first column, fifth row indicates that the mean 3-hour TRMM precipitation within 125 km from the storm center was 1.899 mm/hour. statistics.txt reports all data used in this study. N is line number of the record in ebtrk_atlc_1988-2015.txt I is the intensification rate (hPa/day) Pm is the maximum concurrent precipitation (mm/hour) rP is the radius of maximum precipitation (km) mPm is the mean precipitation within the circle of radius rP (mm/hour) rm is the radius of maximum wind from EBTRK (nm) Prm is precipitation at the radius of maximum wind (mm/hour), if undefined -1 Im is the intensification rate lifetime maximum used in the analysis? 0 No, 1 Yes Name Name of the storm Month Month Day Day Time time Year year simulations.zip contains the input_sounding, namelist.input and onefile.F files for PSE, REV and NOEV simulations, respectively, see the Methods section and the CM1 model description at https://www2.mmm.ucar.edu/people/bryan/cm1/ .
ebtrk_atlc_1988_2015.txt 为2016年7月27日上传的EBTRK(Extended Tropical Cyclone Best Track Dataset,热带气旋扩展最佳路径数据集)版本,详情见https://rammb2.cira.colostate.edu/research/tropical-cyclones/tc_extended_best_track_dataset/。该文件第3437行至11824行对应1998—2015年的热带气旋,共计8387条记录。 pre-wv-new-2023.zip 包含2组各8387个文件,对应上述8387条记录的TRMM(Tropical Rainfall Measuring Mission,热带降雨测量任务)降水分布数据。例如,文件pre-wv-new-04568.txt 对应EBTRK数据集中2000年9月15日18:00的AL1200 HELENE风暴。该文件包含70行数据,对应以风暴中心为原点、距离r_i = i×25 km的环状区域,其中i为行号,取值范围为25 km ≤ r_i ≤ 3000 km。第一列数值为以距离风暴中心不超过r_i且不小于r_{i-1}(r_0=0)的TRMM像元为样本的局地TRMM降水均值(单位:mm/hour),缺失值记为-1。第五列则为用于计算该均值的TRMM像元总数。以第4568条记录为例,第五行第一列的数值1.672表示:距离风暴中心100 km至125 km范围内的3小时TRMM平均降水为1.672 mm/hour,本次计算共使用26个TRMM像元。 其余列与本研究无关,但Makarieva等人2017年的研究(https://doi.org/10.1016/j.atmosres.2017.04.006)曾用到这些列:第二列为无风暴环境下的TRMM平均降水(mm/hour);第三列为MERRA(Modern-Era Retrospective Analysis for Research and Applications,现代时代回顾性研究与应用分析)水汽含量均值(mm);第四列为无风暴环境下的MERRA水汽含量均值(mm);第六列为用于计算水汽含量的MERRA像元数量;第七列为r_i(单位:km)。 文件pre-wv-int-new-04568.txt 结构与前述一致,但统计的是半径r_i的圆形区域内的TRMM平均降水。以第4568条记录为例,第五行第一列的数值1.899表示:距离风暴中心125 km范围内的3小时TRMM平均降水为1.899 mm/hour。 statistics.txt 包含本研究用到的全部数据。其中:N为ebtrk_atlc_1988_2015.txt中对应记录的行号;I为气旋增强速率(单位:hPa/天);Pm为同期最大降水(mm/hour);rP为最大降水半径(km);mPm为半径rP圆形区域内的平均降水(mm/hour);r_m为EBTRK数据中的最大风速半径(nm,海里);P_rm为最大风速半径处的降水(mm/hour),若未定义则记为-1;I_m为分析中使用的生命周期最大增强速率:0表示未使用,1表示已使用;Name为风暴名称;Month为月份;Day为日期;Time为时刻;Year为年份。 simulations.zip 包含分别用于PSE、REV及NOEV模拟的input_sounding、namelist.input与onefile.F文件,详见研究方法部分及CM1模型说明(https://www2.mmm.ucar.edu/people/bryan/cm1/)。
