近几十年来，北冰洋西部夏季海冰范围和厚度急剧下降，这促使科学家们寻找导致海冰变化的可能因素。一个涡流解决，冰-海洋耦合模式，覆盖整个北冰洋的实施，重点放在西北冰洋。特别注意夏季阿拉斯加沿岸流（ACC），由于低纬度开放水域的太阳辐射，其上层温度较高（高达5°C或更高）。在巴罗点之后的ACC下游，在海冰从海岸撤退的夏季，经常会产生一个表面增强的反气旋涡流，并向加拿大海盆传播。这样的涡旋有一个温暖的核心，它的来源是高温ACC水。一个典型的暖心涡被跟踪。它被困在夏季海冰融化水下面，厚度约为60米。涡核温度可达2-3°C，涡内大部分水的温度超过1°C。通过定义涡动边界，计算了极端条件下1 m厚海冰融化1 600 km 2的涡动热量。
The dramatic decline of summer sea ice extent and thickness has been witnessed in the western Arctic Ocean in recent decades, which has motivated scientists to search for possible factors driving the sea ice variability. An eddy-resolving, ice-ocean coupled model covering the entire Arctic Ocean is implemented, with focus on the western Arctic Ocean. Special attention is paid to the summer Alaskan coastal current (ACC), which has a high temperature (up to 5°C or more) in the upper layer due to the solar radiation over the open water at the lower latitude. Downstream of the ACC after Barrow Point, a surface-intensified anticyclonic eddy is frequently generated and propagate towards the Canada Basin during the summer season when sea ice has retreated away from the coast. Such an eddy has a warm core, and its source is high-temperature ACC water. A typical warm-core eddy is traced. It is trapped just below summer sea ice melt water and has a thickness about 60 m. Temperature in the eddy core reaches 2–3°C, and most water inside the eddy has a temperature over 1°C. With a definition of the eddy boundary, an eddy heat is calculated, which can melt 1 600 km2of 1 m thick sea ice under extreme conditions.
