State Grid makes every effort to ensure reliable power supply
The reporter learned from the State Grid on the 8th that due to the cold wave weather, the power load in Beijing, Tianjin, Shandong and other places continued to rise. The power supply departments in various places closely followed the trend of load changes, strengthened inspections and repairs, and ensured reliable power supply.
Affected by the cooling, Beijing's heating power load has surged, and the maximum power load has increased by 27% over the same period last year.
State Grid Beijing Power quickly launched an emergency three-level response to strengthen power supply service guarantees for six types of places such as heating plants, hospitals, schools, and nursing homes, and increase power supply guarantees for electric heating residents in mountainous areas to ensure that citizens stay warm during the winter.
Tianjin launched the Blizzard Red Warning, and the State Grid Tianjin Electric Power organized more than 1,500 emergency support personnel to stick to the front line of power supply.
Affected by the cold wave weather, on November 8, Shandong's highest electricity load increased by 11% year-on-year, and nearly 10,000 electric power repairers made every effort to ensure the power supply.
State Grid Rizhao Power Supply Company uses intelligent inspection robots, comprehensive monitoring and other intelligent means, combined with manual inspection methods to carry out special inspections of power grid equipment to ensure safe and reliable power supply.

Interpretation
Multiple weather systems trigger heavy snowfall
Why is the cold wave and snowfall in Northeast China and Inner Mongolia so strong?
On November 8, Zhou Chunxiao, chief forecaster of the Liaoning Provincial Meteorological Observatory, and Zhang Guilian, chief forecaster of the Inner Mongolia Autonomous Region Meteorological Observatory, performed interpretation.
Why is there so much snowfall in Northeast and Inner Mongolia?
Zhou Chunxiao analyzed that, overall, the snowfall was caused by the rapid development of multiple weather systems and the intense convergence of cold and warm air.
According to specific analysis, at an altitude of 500hPa, the northeast cold vortex develops strongly, and the low trough moves eastward and uplifts northward, leading to the explosive development of ground cyclones, forming a deep low pressure system from low level to high altitude, and strong dynamic uplift conditions; at the same time, the southwest airflow is transporting sufficient to the northeast region. In the warm and humid air, the water vapor is abnormally strong.
Zhang Guilian added that the thickness of snow cover is also related to temperature and water content of snowflakes.
For example, when the temperature reaches the range of -6°C to -8°C, the snow depth per unit of snowfall will reach the maximum; as the temperature rises, the snow depth per unit of snowfall will decrease significantly.
During this snowfall, the water vapor conditions were good and the temperature was suitable, so the snow thickness was also deep.
Is this snowfall extreme?
Zhou Chunxiao believes that the current process snowfall in western Liaoning has exceeded the historical extreme value since the meteorological record in 1951, and the snowfall in parts of the central and northern parts of the country is still continuing, and there is also the possibility of breaking the historical extreme value.
According to Zhang Guilian, the snowfall is relatively large this time, with moderate to heavy snowfalls in the east, central and south of Inner Mongolia.
From the night of the 5th to the 7th, extreme snowfall events occurred at 32 stations in Inner Mongolia, of which 3 stations broke through the historical extremes, namely Xiwu Banner of Ximeng, Qinglong Mountain of Naiman Banner of Tongliao City, and Kulun Banner.
Why does freezing rain occur in some areas?
Zhou Chunxiao introduced that in the early stage, the cold high pressure on the ground wedged into the bottom layer from west to east, forming a "near-surface cold cushion."
The warm and humid southwest airflow climbs on the cold pad, forming a clear temperature inversion layer at an altitude of 850hPa, especially over the midwestern region of Liaoning, forming a "cold-warm-cold" structure from low to high.
As a result, freezing rain occurred in most parts of Shenyang, northern Anshan, Jinzhou, Yingkou, Fuxin, Liaoyang, Tieling, southern Panjin, and the urban areas of Fushun and Huludao.
