今年冬天是“超级冷冬”？最新回应

Core Viewpoint - The discussion around this winter being extremely cold has gained attention, with insights provided by Zhang Daqian, the chief forecaster at the National Climate Center [1]. Group 1: Definitions and Standards - The National Standards for "Cold Winter" (GB/T33675-2017) and "Warm Winter" (GB/T21983-2020) provide clear definitions for these terms, indicating that a winter is classified as cold or warm only if more than half of the meteorological observation stations meet the respective temperature criteria [2]. - In meteorology, the concepts of cold and warm winters are not predictive but rather retrospective classifications based on winter temperature conditions [2]. Group 2: Current Temperature Predictions - Current numerical models suggest that this winter's temperatures in China will be close to or slightly warmer than the historical average, although there will be significant fluctuations between cold and warm periods [4].
