资源简介：
This data consists of tracks of actual tropical cyclones and hurricanes as emulated by the machine-learning-based Huge Ensemble (HENS) [Mahesh et al., 2025a,b]. The matching between HENS and the actual storm tracks from the International Best Track Archive for Climate Stewardship (IBTrACS) Project, Version 4.01 [Knapp et al., 2010] are described in Zeba et al. [2026].
, , ## 1. Data Description
This document provides a comprehensive overview of the HENS Tropical Cyclone Tracks Dataset, including data description, directory and file structure, file contents, and references.
---
## 2. Directory and File Structure
The HENS tracks are organized chronologically. All ensemble members generated for a specific day are aggregated into a single directory named after the ensemble's initialization date.
### Directory Naming Convention
**`HENS_summer23_YYYYMMDDT000000/`**
* **`YYYYMMDD`**: Initialization date, where
* **`YYYY`** is the four-digit year
* **`MM`** is the two-digit month
* **`DD`** is the two-digit day
### File Naming Convention
Within each daily directory, individual files correspond to the tracks of each ensemble member for that specific initialization date:
**`ensemble_out_0NNNN_YYYY-MM-DD-00-00-00.txt`**
* **`NNNN`**: The HENS ensemble-member number (ranging from **0** to **7423**).
* **`YYYY-MM-DD`** is still the initialization date...,
本数据集包含基于机器学习的大型集合（Huge Ensemble, HENS）[Mahesh等人，2025a、2025b]所复刻的实际热带气旋与飓风路径数据。HENS模拟路径与国际气候管理最佳路径档案（International Best Track Archive for Climate Stewardship, IBTrACS）4.01版[Knapp等人，2010]提供的实际风暴路径之间的匹配方法，详见Zeba等人2026年的研究。
## 1. 数据集概述
本文档全面介绍HENS热带气旋路径数据集，涵盖数据集说明、目录与文件结构、文件内容及参考文献。
---
## 2. 目录与文件结构
HENS模拟的气旋路径按时间顺序组织。针对特定日期生成的所有集合成员数据，将被整合至以该集合初始化日期命名的单一目录中。
### 目录命名规则
**`HENS_summer23_YYYYMMDDT000000/`**
* **`YYYYMMDD`**：集合初始化日期，其中
* **`YYYY`** 为四位年份编号
* **`MM`** 为两位月份编号
* **`DD`** 为两位日期编号
### 文件命名规则
在每个每日目录中，单个文件对应该初始化日期下某一集合成员的气旋路径数据，命名格式为：
**`ensemble_out_0NNNN_YYYY-MM-DD-00-00-00.txt`**
* **`NNNN`**：HENS集合成员编号（取值范围为**0**至**7423**）。
* **`YYYY-MM-DD`** 仍代表集合初始化日期……
