Core Viewpoint - The winter climate in China is expected to be influenced by the La Niña phenomenon, which is predicted to last until early 2026, leading to average national temperatures close to or above normal levels this winter [2][6][7]. Temperature Trends - In October, the national average temperature was 11.1°C, close to the historical average, with a "warm front followed by cold" pattern observed [4]. - The early part of October experienced high temperatures, with some regions in southern China exceeding 38°C, while a significant drop in temperature occurred in the latter part of the month due to cold air masses [5]. La Niña Impact - The La Niña state is expected to result in a winter with average temperatures near or above normal and generally lower precipitation, particularly in southern regions [7]. - The risk of widespread low-temperature rain and snow events in southern China is considered low [7]. Precipitation Patterns - National average precipitation in October was 51.5 mm, which is 51.8% above the historical average, marking the third-highest for this period [8]. - The forecast indicates that certain regions, including northeastern and southwestern areas, will experience above-average precipitation, while others will see near-normal to below-normal levels [9]. Upcoming Weather Forecast - The next ten days are expected to see higher temperatures in most northern regions, with average temperatures 1-3°C above or close to normal levels [8]. - Rainfall is anticipated in various regions, with specific areas in the southwest and south experiencing significant precipitation events [9].
