Core Viewpoint - The article discusses a significant temperature increase in the central and eastern regions of China, with some areas breaking historical records, followed by a forecasted sharp drop in temperatures due to incoming cold air [1]. Weather Forecast Summary - On December 19, temperatures in Nanjing reached over 20°C, significantly higher than the usual 10°C for mid-December, marking a record high [1]. - A cold air mass is expected to move from north to south, leading to a "cliff-like" drop in temperatures across most of the central and eastern regions, returning to seasonal averages [1]. - A blue cold wave warning has been issued for Jiangsu Province, predicting a temperature drop of 8-9°C in certain areas and 6-7°C in others from December 20 to 22 [1]. - The lowest temperatures are anticipated on the morning of December 22, with northern areas potentially reaching around -2°C and localized frost expected [1]. Precipitation and Drought Conditions - Jiangsu has been experiencing below-average precipitation, with southern regions facing moderate to severe drought conditions [1]. - Light rain is expected in some areas south of the Huai River on December 20, but the rainfall is likely to be insufficient to alleviate drought conditions, serving only to slightly moisten the environment [1]. - Additionally, fog and haze are forecasted for December 20, necessitating public health precautions, with improvements expected after December 21 [1].

Report Summary 1) Report Industry Investment Rating No information provided. 2) Core View of the Report On December 15th, the domestic commodity futures market closed with mixed results. New energy materials, shipping futures, black commodities, precious metals, non - metallic building materials, most chemicals, energy products, and most agricultural and sideline products showed gains, while basic metals and all oilseeds and fats declined. Industrial products had a differentiated performance, and agricultural products were also mixed [1]. 3) Summary by Related Catalogs Black Commodities - Most black commodities rose. Recently, the supply and demand of steel were both weak, and the steel futures market remained weak. Affected by the cold wave, outdoor construction was further restricted, and the apparent demand for the five major steel products last week dropped to 839.72 million tons, the lowest in the same period in recent years, with a month - on - month decline of 2.83%. Although the fundamentals were not strongly driven, policy factors might cause fluctuations. In the short term, due to positive domestic and foreign macro - expectations, steel trading was active, and steel prices still had the impetus to rebound, but the upward space was limited, with a medium - term weak outlook [1]. Basic Metals - This category had the largest decline. For copper, after the Fed's interest rate cut and restart of Treasury bond purchases, the liquidity expectation was marginally relaxed, and the tone of the Central Economic Work Conference was positive. Although the short - term bullish sentiment cooled, the risk of continuous decline in copper prices was small, and it might shift to a volatile trend. The supply of copper ore remained tight, the supply of refined copper in China was expected to increase, but the downstream operating rate was stable, and the surplus pressure was not significant. - Lithium carbonate first fell and then rose. The arrival volume of lithium ore at ports was expected to increase month - on - month in the next month, and the tight supply situation at the mine end was expected to ease marginally. The resumption of production at lithium mines was in progress. The high - growth demand for energy storage continued, the supply - demand pattern of lithium carbonate had not changed, and social inventories continued to decline, which supported the strong operation of futures prices [1]. Energy and Chemical Products - The movement of energy and chemical products was volatile. On Monday, the main contract of SC crude oil was hesitant, and the market sentiment became more cautious. In the short term, crude oil inventories decreased while refined oil inventories increased significantly, and the fundamentals remained under pressure. Geopolitical and macro - factors were still uncertain, and oil prices were under pressure and volatile. In the medium term, the contradiction of oversupply was predominant, and the center of oil prices might decline. However, there was a risk of upward correction in oil prices from December to January due to the resonance of geopolitical risks, cold wave impacts, and low - inventory destocking [1]. Oilseeds and Fats - All oilseeds and fats declined. Due to weak US export demand and the upcoming harvest in Brazil, traders closed their long positions, and US soybeans fell to a seven - week low. In the domestic market, both soybean meal and rapeseed meal were weak. The main contract of soybean meal increased in positions and declined, and the main contract of rapeseed meal also slightly declined. The market lacked the impetus to continue rebounding. In addition to the weak external market suppressing the cost of soybean imports, the domestic soybean meal market fundamentals were also bearish. Although the short - term spot prices were supported, the far - month contracts were still suppressed by the loose supply pattern. The electronic trading of CBOT soybean oil oscillated at a low level. The uncertainty of the US biodiesel policy was bearish for the soybean oil market, and the decline of US soybeans also dragged down the domestic oil market. The main contracts of soybean oil and palm oil both declined, and the decline of rapeseed oil futures was obvious. The abundant international supply continued to pressure the market. Although the news of strict customs inspections on non - genetically modified rapeseed oil imports briefly boosted the market sentiment, the impact on actual supply and demand was limited, and the speculation sentiment in the rapeseed oil market cooled. The near - term supply should focus on the crushing rhythm of Australian rapeseeds [1].

Core Viewpoint - The recent cold wave has significantly impacted Suzhou's weather, leading to a sharp drop in temperatures, with the city experiencing challenges in officially entering winter despite previous cold fronts [1] Weather Conditions - Suzhou has faced two previous cold waves this winter, both of which were intense but short-lived, resulting in quick temperature rebounds after their passage [1] - The latest weather forecast indicates that aside from a rain event on the night of the 20th to the day of the 21st, the week will primarily feature changes in cloud cover [1] - The lowest temperature recorded was around 0°C on the morning of the 15th, attributed to the influence of cold air and clear night skies [1] Temperature Trends - Following the recent cold air mass, temperatures in Suzhou are expected to gradually rise, with maximum temperatures projected to exceed 10°C in the short term [1] - The city is still monitoring whether the average temperature can remain below 10°C for five consecutive days, which is a criterion for officially marking the onset of winter [1]
