High-impact weather events are often accompanied by temperatures near 0°C and precipitation in the form of freezing rain and wet snow. These can lead to catastrophic consequences and their occurrence will change in the future. The goal is to improve our understanding of the factors responsible for extreme winter weather events, such as the type, intensity and duration of precipitation. These will be addressed using state-of-the art numerical tools and unique observation networks. It is essential to better understand the fundamentals of storms and associated precipitation to anticipate their occurrence in a context of ongoing and future climate change.

高影响天气事件往往伴随着接近0摄氏度的温度和以冻雨和湿雪形式存在的降水。这些可能会导致灾难性的后果，它们的发生将在未来发生变化。目标是提高我们对极端冬季天气事件的原因的了解，例如降水的类型、强度和持续时间。这些问题将使用最先进的数字工具和独特的观测网络来解决。必须更好地了解风暴和相关降水的基本原理，以便在当前和未来气候变化的背景下预测它们的发生。
