Future changes to the intensity and frequency of short‐duration extreme rainfall

…, EJ Kendon, G Lenderink, NM Roberts - Reviews of …, 2014 - Wiley Online Library
Evidence that extreme rainfall intensity is increasing at the global scale has strengthened
considerably in recent years. Research now indicates that the greatest increases are likely to …

[HTML][HTML] Scale-selective verification of rainfall accumulations from high-resolution forecasts of convective events

NM Roberts, HW Lean - Monthly Weather Review, 2008 - journals.ametsoc.org
The development of NWP models with grid spacing down to 1 km should produce more
realistic forecasts of convective storms. However, greater realism does not necessarily mean …

Heavier summer downpours with climate change revealed by weather forecast resolution model

EJ Kendon, NM Roberts, HJ Fowler, MJ Roberts… - Nature Climate …, 2014 - nature.com
The intensification of precipitation extremes with climate change 1 is of key importance to
society as a result of the large impact through flooding. Observations show that heavy rainfall is …

…, WS Wu, DF Parrish, NM Roberts - Monthly Weather …, 2003 - journals.ametsoc.org
In this second part of a two-part study of recursive filter techniques applied to the synthesis of
covariances in a variational analysis, methods by which non-Gaussian shapes and spatial …

Structure of a frontal cyclone

KA Browning, NM Roberts - Quarterly Journal of the Royal …, 1994 - Wiley Online Library
A diagnostic study of a mid‐latitude cyclone has been carried out using routinely available
numerical weather‐prediction model products and imagery. The cyclone was intense but not …
