It is distinctly unusual to observe fresh surface-based convection, sufficient to generate heavy showers, developing inland around the winter solstice over Britain, due to the weakness of insolation. This case study demonstrates, however, that this is indeed possible across southern England, with limited diurnal heating, given moist and slightly unstable profiles. However, it was almost certainly the presence of larger scale dynamically forced ascending motion that assisted the observed rapid growth of convection.

冬季内陆地表对流？

由于日照较弱，观察到新鲜的地表对流足以产生大阵雨，并在冬至前后在英国内陆发展，这显然是不寻常的。然而，这个案例研究表明，这在英格兰南部确实是可能的，考虑到潮湿和稍微不稳定的剖面，昼夜加热有限。然而，几乎可以肯定的是，更大规模的动态强迫上升运动的存在有助于观察到的对流的快速增长。
