weather and climate science and services to reduce the risk from weather and climate. Developing a “seamless” weather and climate modelling system requires the partnership to: • Carry out world leading weather and climate science and translate this into a prediction system; • Deliver technological

The dynamical core Modern computer models of the atmosphere include many complex physical processes that each have local influences and feed back into the general circulation. At the heart of these models, however, is the solution of the dynamical equations of motion (Newton's laws applied to a gas

Lizzie is a Scientific Manager and Met Office Science Fellow, leading pioneering work to use very high resolution (km-scale) climate models for understanding future changes in high impact weather events.

. These models are also able to better represent the influence of mountains, coastlines and cities on our local climate compared to more traditional climate models. As a result, convection-permitting models are able to provide credible projections of future changes in local weather extremes, including

in regional climate. These simulations are being used to study urban influences on the present-day and future climate of Johannesburg, South Africa. The improved representation of rain shower and thunderstorm formation in these simulations has provided new insights into the relationship between

).1.2 Seasonal climate drivers of South Asia 1.2 Seasonal climate drivers of South Asia The climate of South Asia varies from year-to-year due to the influences of large-scale climate drivers that vary on interannual and intraseasonal timescales. The key drivers of this variability are described

assumptions about the economic, social and physical changes to our environment that will influence climate change. Representative Concentration Pathways (RCPs) used in IPCC AR5, and Shared Socio- Economic Pathways (SSPs) used in IPCC AR6 are both methods for capturing those assumptions within a set

The influence of mountains and hills on both local weather and large-scale weather systems.

blocking, hills and mountains influence the development of weather systems and the global atmospheric circulation. These processes need to be represented in weather and climate prediction models. Our research explores several aspects of atmospheric flow over orography. These include investigations

Climate Change (OCDC) group. His research interests include: the impact of resolution and vertical coordinate systems on the ocean models’ representation of the bottom topography influence on the oceanic flow (e.g., gravity currents, currents steering); accurate numerical schemes for computing horizontal

Agreement guard rails will be crucial. Without an agreement on what actually will count as exceeding 1.5 °C, we risk distraction and confusion at precisely the time when action to avoid the worst effects of climate change becomes even more urgent.” New indicators for Global Warming levels Some
