冰岛低压位于大西洋北部冰岛附近，为副极地低压带上的一个半永久性低压中心，其强度和范围随季节而变化。
举例来说，英国冬天的气侯是与冰岛低压和亚速尔高压有紧密联系的。
The weather we get in UK winters, for example, is strongly linked to the contrasting pressure between the Icelandic low and the Azores high.
当它在比以前更长的时间里保持不结冰的状态，它也会将更多的热量输入北极区的大气层，这就使北极区的气压变高，使冰岛低压和亚速尔高压之间的梯度变小。
As it remained clear for longer than usual it also bled more heat into the Arctic atmosphere. This caused higher air pressures, reducing the gradient between the Iceland low and the Azores high.
