Recently, the reporter learned from the National Meteorological Center that since November 2023, the cold wave process in my country has been numbered. This is an important measure to improve the accuracy and service level of cold wave forecasting and early warning.
According to reports, the cold wave event is closely related to traffic safety, agricultural production, energy dispatch, human health, etc., and has strong disaster and impact. In the context of global warming, although the number of cold waves affecting China is generally decreasing, extreme cold wave weather and the economic losses caused by it are increasing, which puts forward higher requirements for cold wave forecasting and early warning. In this regard, the National Meteorological Center has established a high-frequency, multi-channel early warning mechanism for cold waves and blizzards.
Since February 2023, on the basis of scientifically connecting the short-term cold wave warning specifications and the medium-term cold wave business regulations, the National Meteorological Center has formulated a new specification for the cold wave survey and numbering business, which divides the cold wave into "cold wave", "strong cold wave" and "super cold wave" according to factors such as the time of cooling occurrence, regional scope, and intensity.
The cold wave number will provide a scientific basis for all levels and relevant departments to formulate prevention and response measures, and will also provide an important reference for the public to do a good job of cold protection and warmth.
In the next step, the National Meteorological Center will also develop more abundant monitoring and forecasting products, and further optimize and adjust the business process to support the standardization and standardization of cold wave numbering services.
