Core Viewpoint - The article discusses the impact of Typhoon "Zhu Jie Cao" on Beijing's rainfall, highlighting the indirect influence of the typhoon through moisture transport, leading to significant rainfall events in the region [2][3]. Group 1: Typhoon Influence - Typhoon "Zhu Jie Cao" has indirectly affected Beijing's rainfall by enhancing moisture conditions, although the primary influence comes from a high-altitude trough [2]. - The typhoon, which weakened on the 26th but regained strength, contributes to the moisture supply that enhances rainfall predictions for Beijing [2][3]. Group 2: Rainfall Predictions - Without the influence of the typhoon's moisture, the rainfall in Beijing would likely be less intense, but the current predictions indicate heavier rainfall due to the added moisture from the typhoon [3]. - Rainfall is expected to taper off after the daytime of the 29th, with a brief period of reduced precipitation before another significant rainfall event around August 3rd [4]. Group 3: Rainfall Characteristics - The rainfall distribution in Beijing is uneven, with some areas experiencing heavy rainfall while others remain dry, attributed to different weather systems affecting the region [4][6]. - The rainfall on the night of the 28th is characterized as a systematic and predictable weather event, although there are challenges in forecasting due to the influence of cold air and local topography [7].
