The Influence of El Niño Events on the Climate of Northeastern China: An Integrated Analysis

Abstract

The year 2023 has been projected to be potentially the warmest year since 1850, largely attributed to the El Niño phenomenon, highlighting its significant impact on global climate patterns, including those affecting China [1] The occurrence of El Niño has been linked to extreme weather transitions in China, from unusually warm conditions to sudden freezing temperatures, underscoring the variability and extremity introduced by this climatic event [2]. Research further suggests that the combination of El Niño and the Atlantic Multidecadal Oscillation (AMO) has contributed to the remarkably large margin of global temperature increases observed in 2023 [3]. This assertion is supported by the World Meteorological Organization’s confirmation that 2023 has indeed shattered global temperature records, emphasizing the profound influence of El Niño on exacerbating climate anomalies worldwide, including in China[4]. This study aims to delve deeper into the mechanisms through which El Niño influences China’s climate, particularly focusing on temperature variations and the incidence of extreme weather events, to understand better the broader implications of such climatic phenomena on regional and global scales.
