Evaluation of a sub-kilometre NWP system in an Arctic fjord-valley system in winter
Terrain challenges the prediction of near-surface atmospheric conditions, even in kilometre-scale numerical weather prediction (NWP) models. In this study, the ALADIN-HIRLAM NWP system with 0.5 km horizontal grid spacing and an increased number of ...

Verification of pre-monsoon temperature forecasts over India during 2016 with a focus on heatwave prediction [PDF]
The operational medium-range weather forecasting based on numerical weather prediction (NWP) models are complemented by the forecast products based on ensemble prediction systems (EPSs).

Validation metrics for ice edge position forecasts [PDF]
The ice edge is a simple quantity in the form of a line that can be derived from a spatially varying sea ice concentration field. Due to its long history and relevance for operations in the Arctic, the position of the ice edge should be an essential ...

A method is presented for deriving probabilistic medium‐range (1‐to‐2‐week) weather pattern forecasts for India. This method uses an existing set of 30 objectively derived daily weather patterns, which provide climatological representations for unique ...

On the warm bias in atmospheric reanalyses induced by the missing snow over Arctic sea-ice
Contemporary atmospheric reanalysis and forecast systems often neglect the snow layer on top of the sea ice. This can result in a 5 to 10 °C warm bias of the sea-ice surface temperature and thus, in a misrepresentation of the surface energy budget.

We assess the skill of the fully coupled lagged ensemble forecasts from GloSea5‐GC2, for the sub‐seasonal to seasonal (S2S) timescale up to 4 weeks, with the aim of understanding how these forecasts might be used in a Ready‐Set‐Go style decision‐making ...

Arctic Atmospheric Ducting Characteristics and Their Connections with Arctic Oscillation and Sea Ice
Atmospheric ducting is an anomalous atmospheric structure that affects electromagnetic wave propagation. In the context of global warming, the navigation capacity of the Arctic is increased, and the atmospheric duct can affect communication and ...
