Abstract
Using a multi-model approach, this paper quantifies global changes in moderate or greater mountain wave turbulence (MWT) within a high-end warming scenario by 2050. We first show that simulated MWT changes depend on model resolution and therefore select three high resolution global climate model experiments for further analysis; HadGEM3-GC3.1-HM (25 km), EC-Earth-3P-HR (36 km) and MPI-ESM1.2-XR (34 km). The wide model and index uncertainty across continental average projections lead to a sub-continental 28 area approach. Using this method, we determined MWT is projected to increase over North America as a whole but decrease over the Rocky Mountains. An increase in MWT is projected for other regions including the Antarctic, Greenland, Georgia, Azerbaijan and parts of Chile and Argentina. A decline in MWT is projected for the Alps, Atlas and northern and central Andes. We also explore the modelled relationship of 10 m wind speed and MWT production; there is a positive correlation between the projected changes of MWT and surface wind speed. The aviation sector should be aware of the future projections in MWT, particularly for regions where a large increase in MWT is projected, such as the Antarctic and Greenland.
Abstract. This study presents a new set of high-resolution global climate simulations conducted with the EC-Earth3 model, including a 350 year pre-industrial, followed by historical (1850–2014) and future (2015–2100, SSP2-4.5) simulations. The model features a horizontal resolution of ∼ 40 km in the atmosphere and 0.25...

Long multi-decadal transient convection-permitting climate simulations are crucial for reliable regional climate projections. However, the large computational resources required are often not available, particularly in the context of African climate change studies. This poses challenges for regions like the Lake Vict...

Extreme precipitation over East Asia is projected to intensify in the future at a rate greater than that expected from temperature-based scaling. However, substantial uncertainty remains in projections of extreme precipitation at regional scales. Using four high-resolution climate models under the SSP5-8.5 scenario, we...

Quantifying climate change across standardized reference periods is essential for tracking the pace and spatial structure of ongoing shifts in Earth’s climate system. However, robust and comprehensive global comparisons between consecutive climatological normals remain absent. Using high-resolution ERA5-Land reanalysis...

This paper reports on two sets of 22-year convection-permitting regional climate simulations conducted with the Weather Research and Forecasting model over the entirety of South America at 4-km grid spacing. The first simulation downscales the fifth-generation European Centre for Medium-Range Weather Forecasts atmosphe...

The Kuroshio extension (KE) plays a key role in the North Pacific climate through its strong heat transport and wintertime air–sea fluxes. Low-resolution Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models, however, continue to show structural biases such as unrealistic Kuroshio overshooting. To...
