由于雪与温暖空气之间复杂的相互作用,预测者面临着预测冬季温暖前线的挑战。 Forecasters face challenges predicting winter warm fronts due to the complex interaction between snow and warm air.

最近的气温波动突显了预测冬季温暖前线的挑战,特别是地面积雪时的挑战。 Recent fluctuating temperatures highlight the challenges in forecasting winter warm fronts, especially with snow on the ground. 雪会反射阳光和发热,在地面附近形成冷层,温暖的空气必须升起。 Snow reflects sunlight and radiates heat, creating a cold layer near the ground that warm air must rise over. 这种复杂性使得天气模型难以作出准确的地表温度预测,而主要预报者则依赖经验和仔细分析。 This complexity makes accurate surface temperature predictions difficult for weather models, leading forecasters to rely on experience and careful analysis.
