Core Viewpoint - The northern regions of China, particularly North China, are experiencing an unusually prolonged rainy season, with significant rainfall exceeding historical averages, attributed to various climatic factors [2][3][4]. Summary by Sections Rainfall Patterns - The rainy season in North China began on July 5, 2023, which is 13 days earlier than the average, marking the earliest start since 1961 [2]. - As of August 25, 2023, the cumulative rainfall in the monitoring area of North China was 131% higher than the average [2]. Climatic Influences - The excessive rainfall is linked to abnormal sea temperatures in the equatorial Pacific, a strong and shifted subtropical high-pressure system, typhoon activity, and geographical factors [3]. - The subtropical high-pressure system has been notably strong and has shifted northward, allowing for continuous moisture transport from the ocean to northern regions [3]. Weather Systems and Topography - The influence of Typhoon "Zhu Jie Cao" has contributed additional moisture to North China, enhancing rainfall [4]. - The topographical features, such as the Taihang and Yanshan mountains, have caused forced uplift of warm, moist air, leading to increased precipitation through condensation and convection [4]. Climate Change Context - The record-breaking rainy season is seen as a localized manifestation of climate change, highlighting the need for improved climate adaptation and response capabilities to handle extreme weather events [4].
