石笋中的发光有机物可能形成年度带，从而可以精确确定生长速度。石笋的生长速度受降水量控制，因此年带可用于得出长期降水记录。苏格兰西北部一个洞穴中的连续带状石笋被用来提供 1100 年的高分辨率降水记录。洞穴的位置意味着降水与北大西洋涛动密切相关，对此也有记录。这表明北大西洋涛动状态的变化是过去千年对欧洲气候的重要控制因素。
Luminescent organic matter in stalagmites may form annual bands, allowing growth rate to be precisely determined. Stalagmite growth rate is controlled by precipitation, so annual bands can be used to derive long precipitation records. A continuously banded stalagmite from a cave in NW Scotland was used to provide a 1100 year high-resolution record of precipitation. The location of the cave means that precipitation is closely linked to the North Atlantic Oscillation, for which a record is also derived. This suggests that changes in the North Atlantic Oscillation state was an important control on European climate over the past millennium.
