| 摘 要： | 本文分析了日本海发生的一次极地低压的水平结构和垂直结构,极地低压的"眼"处几乎无云,由螺旋状云系环绕,并伴有较强的下沉气流,具有暖核结构。热力学收支表明,该暖核主要是由伴随下沉气流的绝热增暖造成的。

| Abstract: | This article analyses the structures both in the vertical and in the horizontaldimensions of a polar low event that occurred over the Japan Sea.The"eye"is occupiedby a dry air,surrounded by spiral cloud patterns and associated with a strong downdraft,has a warm core,and is almost free of cloud.The thermodynamic budget analysis indicatethat this "warm core"is mainly caused by the adiabatic warming associated with the downdraft. |

| Keywords: | polar lows warm core spiral cloud bands |
