Quarterly Journal of the Royal Meteorological Society, EarlyView.This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Spatial and temporal patterns of SST uncertainty
Quarterly Journal of the Royal Meteorological Society, EarlyView.This figure summarises the change in the Operational Sea Surface Temperature and Sea Ice Analysis near‐real‐time sea‐surface temperature product uncertainty spatial pattern in the UK domain as cluster maps broken into three time periods: (a) June 2007–February 2014; (b) March 2014–February 2018; (c) March 2018–December 2022.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Atmospheric electricity data require local weather information for identifying representative ‘fair weather’ values, which are needed for climate‐related studies. ERA5 meteorological reanalysis data are evaluated for this, by comparison with data from Lerwick observatory, Shetland, where a long series of twentieth‐century potential gradient ...

Decadal variability of Madden–Julian oscillation teleconnections in a coupled climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.The Madden–Julian oscillation (MJO) is a key predictor of extratropical weather, such as the North Atlantic oscillation, through its teleconnection patterns. These teleconnection patterns are known to vary over a range of time‐scales, but the way in which they vary on decadal time‐scales is not well understood.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a compatible finite‐element discretisation of a general formulation of moist shallow‐water equations, with the aim of providing a simple model to advance understanding of physics–dynamics coupling. We detail set‐ups and show three moist shallow‐water test cases in four different model formulations. The results demonstrate differences between

Joint modulation of coastal rainfall in Northeast Australia by local and large‐scale forcings
Quarterly Journal of the Royal Meteorological Society, EarlyView.Spatially heterogeneous rainfall patterns over the coastal regions of northern Queensland are consistent between radar observations and model simulations. Rainfall propagation modulates the average rainfall distribution, leading to inhomogeneous rainfall patterns along the coast.

Quarterly Journal of the Royal Meteorological Society, EarlyView.The ENSO–East Asia teleconnection exhibits strong subseasonal variability, driven by ENSO‐related tropical convection anomalies over the Indian Ocean, Maritime Continent, and central Pacific. GloSea6 fails to accurately predict this teleconnection due to errors in simulating the convection anomalies‐induced teleconnection patterns.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Schematic of the computation of the logarithmic score and information gain. In panel (a), ensemble predictions (orange circles), observational reference (red circle), and historical observations (blue circles) are shown. An ensemble prediction probability distribution (orange line) and a climatological probability distribution (blue line) are also ...

Evaluating seasonal forecast improvements over the past two decades
Quarterly Journal of the Royal Meteorological Society, EarlyView.We have analysed the performance of operational seasonal forecasting models since their inception. Clear improvements are measured through the different model eras, particularly in the Tropics. For the extratropics, the strongest improvements are evident during the boreal winter season over the North Pacific/North America, linked to improvements in the
