WINTER MINIMUM TEMPERATURE VARIATIONS IN YIXING: A COMPARATIVE ANALYSIS

Abstract

Yixing, situated in the southwestern region of Jiangsu province, displays marked variations in winter minimum temperatures due to its intricate topographical and landscape features. Given the backdrop of global climate shifts and the increasing frequency of extreme weather events, there arises an imperative to advance predictive technologies for meteorological disasters characterized by extremely low temperatures. As urbanization, rapid economic growth, population expansion, and the progress of facility agriculture surge ahead, areas at high risk for low-temperature phenomena like rain, snow, and ice have migrated from northwest to southeast China. While the overall risk of low temperatures in southern China is declining, the potential for major disasters has surged in recent times. Prior studies have laid a robust theoretical foundation for bolstering the monitoring and diagnosis of extreme low-temperature weather events. These studies also provide critical insights into the distinctive features of winter low temperatures in Yixing. Nevertheless, these endeavors often encompass spatial scales too extensive to be directly applicable to the Yixing region, where notable local microclimatic discrepancies frequently arise. This study endeavors to leverage station data specific to the Yixing area, conducting a comprehensive analysis of winter minimum temperatures across the county. The aim is to elucidate the fundamental causes of these variances, ultimately refining the forecasting of low-temperature events
