Lake Ice Will Be Less Safe for Recreation and Transportation Under Future Warming

Earth's Future, 2022
Millions of lakes from around the world freeze during winter. These frozen surfaces provide essential ecosystem services that are vital to many northern communities.

Statistical ensemble of large-eddy simulations [PDF]

Journal of Fluid Mechanics, 2002
A statistical ensemble of large-eddy simulations (LES) is run simultaneously for the same flow. The information provided by the different large-scale velocity fields is used in an ensemble-averaged version of the dynamic model. This produces local model parameters that only depend on the statistical properties of the flow.

Large Ensemble Simulation for Investigating Predictability of Precursor Vortices of Typhoon Faxai in 2019 With a 14‐km Mesh Global Nonhydrostatic Atmospheric Model

Geophysical Research Letters, 2023
Typhoon Faxai hit Japan in 2019 and severely damaged the Tokyo metropolitan area. To mitigate such damages, a good track forecast is necessary even before the typhoon formation. To investigate the predictability of the genesis and movement of a precursor

European heatwave tracks: using causal discovery to detect recurring pathways in a single-regional climate model large ensemble

Environmental Research Letters, 2023
Summer heatwaves repeatedly affect extended regions in Europe, resulting in adverse economic, social, and ecological impacts. Recent events, e.g. the 2022 heatwave, also attract interest regarding the spatial shifts of their impact centers.

How extreme could the near term evolution of the Indian Summer Monsoon rainfall be?

Environmental Research Letters, 2022
We provide a methodology to estimate possible extreme changes in seasonal rainfall for the coming decades. We demonstrate this methodology using Indian summer monsoon rainfall as an example.

Reconstruction of Zonal Precipitation From Sparse Historical Observations Using Climate Model Information and Statistical Learning

Geophysical Research Letters, 2022
Future projected changes in precipitation substantially impact societies worldwide. However, large uncertainties remain due to sparse historical observational coverage, large internal climate variability, and climate model disagreement.

The SMHI Large Ensemble (SMHI-LENS) with EC-Earth3.3.1 [PDF]

Geoscientific Model Development, 2021
The Swedish Meteorological and Hydrological Institute used the global climate model EC-Earth3 to perform a large ensemble of simulations (SMHI-LENS). It consists of 50 members, covers the period 1970 to 2100, and comprises the SSP1-1.9, SSP3-3.4, SSP5-3 ...

Internal Climate Variability in the Present Climate and the Change in ENSO Amplitude in Future Climate Simulations

Frontiers in Climate, 2022
In this study, we define a metric for the intensity of internal climate variability (ICV) based on global surface temperature in the present climate and suggest that it can be used to understand the diversity of projected changes in ENSO amplitude in the
