摘要

基于机器学习中的超分辨率重构技术

提出基于混合下采样跳跃连接（DSC）/多尺度（MS）模型的台风三维风场超分辨率重构方法

开展不同网格尺度之间的三维风场超分辨率重构研究。通过对比分析台风整体流场、空间不同区域平均风剖面、径向风速分布等误差

结果表明

千米及以下尺度风场可较好地重构精细化台风三维风场

而千米尺度以上风场重构误差较大

初步实现了台风风场重构从千米量级到百米量级跨越。

Abstract

Based on the super-resolution reconstruction technique in machine learning

this paper proposes a hybrid downsampling skip connection （DSC）/multi-scale （MS） model for super-resolution reconstruction of three-dimensional typhoon wind fields

and conducts research on super-resolution reconstruction of three-dimensional wind fields across different grid scales. Through comparative analysis of errors in the overall typhoon flow field

average wind profiles in different spatial regions

and radial wind speed distributions

the results indicate that wind fields at kilometer-scale and below can effectively reconstruct refined three-dimensional typhoon wind fields

while reconstruction errors are relatively larger for wind fields above kilometer-scale. This study preliminarily achieves a transition in typhoon wind field reconstruction from kilometer-scale to hectometer-scale.
