Abstract

Plateau mountainous regions exhibit complex and diverse terrain characteristics, with varying altitudes and extensive land coverage. These areas are subject to a complex and diverse climate, particularly during the period from November to March, where the intricate microtopography in the plateau mountainous areas leads to highly complicated local weather conditions. Under adverse geographical and micro-meteorological environments, these regions are prone to transmission line icing disasters. The main factors influencing ice accretion on vulnerable microtopography differ according to different microtopographic types. This study focuses on the Guizhou region as the research object and divides it into different zones based on its geographical and climatic conditions. Within these zones, analysis and modeling are conducted for ridge lines, valleys, passes, and windward slopes. Finally, through cross-validation of the models and comprehensive analysis of the results, the key factors influencing ice accretion on various types of vulnerable microtopography in different zones are identified.
