A major forecasting challenge is predicting the likely intensity of rainfall in convective situations in which intense short‐period rainfall can lead to surface water flooding. The study demonstrates a useful correlation between precipitable water and 1 hr gauge‐derived rainfall accumulations in situations with deep instability and relatively slack flow in depth. The correlation forms the basis of a forecasting technique, independent of numerical weather prediction (NWP) model forecasts of rainfall, being applied at the UK's Met Office Flood Forecasting Centre (FFC).

短期对流日降水量与总柱上可降水量的比较：一种操​​作预报技术的推导

一个主要的预测挑战是在对流情况下预测可能出现的降雨强度，在这种情况下强烈的短时降雨会导致地表水泛滥。这项研究表明，在深度不稳定和深度相对较松散的情况下，可降水量水与1小时尺度的降雨积累之间存在有用的关联。这种相关性是独立于英国气象局洪水预报中心（FFC）的预报技术的基础，与天气预报的数值天气预报（NWP）模型预报无关。
