Press release: Met Office leads ground-breaking research collaboration on modelling African climate, showing enhanced future changes in wet and dry extremes

Jean-Pierre Roux, Zablone Owiti, Beth Mackay, Elizabeth Kendon, Cath Senior, Dave Rowell, John Marsham, Rachel James, Wilfried Pokam

A 4-year investment into one of the most ambitious research collaborations to date that focuses on African climate has delivered far-reaching results to advance international climate science. The international collaboration, led by the Met Office, the UK’s national meteorological service, has developed the first…

Significantly increased extreme precipitation expected in Europe and North America from extratropical cyclones

Matt Hawcroft, Ella Walsh, Kevin Hodges and Giuseppe Zappa

For the Northern Hemisphere extratropics, changes in the mid-latitude storm tracks are key to understanding the impacts of climate warming, but projections of their future location in current climate models are affected by large uncertainty. Here, we show that in…

A pan-Africa convection-permitting regional climate simulation with the Met Office Unified Model: CP4-Africa

Stratton, R., Senior, C., Vosper, S., Folwell, S., Boutle, I., Earnshaw, P., Kendon, E., Lock, A., Malcolm, A., Manners, J., Morcrette, C., Short, C., Stirling, A., Taylor, C., Tucker, S., Webster, S. and Wilkinson, J.

A convection-permitting multiyear regional climate simulation using the Met Office Unified Model has been run for the first time on an Africa-wide domain. The model has been run as part of the Future Climate for Africa (FCFA) Improving Model Processes…

Regional climate impacts of stabilizing global warming at 1.5 K using solar geoengineering

Jones, A. C., Hawcroft, M. K., Haywood, J. M., Jones, A., Guo, X., & Moore, J. C.

The 2015 Paris Agreement aims to limit global warming to well below 2 K above preindustrial levels, and to pursue efforts to limit global warming to 1.5 K, in order to avert dangerous climate change. However, current greenhouse gas emissions…

The contrasting climate response to tropical and extratropical energy perturbations

Hawcroft, M.,Haywood, J., Collins, M., Jones, A.

The link between cross-equatorial energy transport, the double-intertropical convergence zone (DI) problem and biases in tropical and extratropical albedo and energy budgets in climate models have been investigated in multiple studies, though DI biases persist in many models. Here, a…

Impacts of hemispheric solar geoengineering on tropical cyclone frequency

Jones, A., Haywood, J., Dunstone, N., Emanuel, K., Hawcroft, M., Hodges, K.

Solar geoengineering refers to a range of proposed methods for counteracting global warming by artificially reducing sunlight at Earth’s surface. The most widely known solar geoengineering proposal is stratospheric aerosol injection (SAI), which has impacts analogous to those from volcanic…

Simulating the characteristics of Tropical Cyclones over the South West Indian Ocean using a Stretched-Grid Global Climate Model

Molulaqhooa L. Maoyi, Babatunde J. Abiodun, Joseph M. Prusa, Jennifer J. Veitch

Tropical cyclones (TCs) are one of the most devastating natural phenomena. This study examines the capability of a global climate model with grid stretching (CAM-EULAG, hereafter CEU) in simulating the characteristics of TCs over the South West Indian Ocean (SWIO).…
