The contribution of internal climate variability to climate change impacts on droughts
Science of The Total Environment, 2019The assessment of climate change impacts is usually done by calculating the change in drought conditions between future and historical periods by using multiple climate model simulations. However, this approach usually focuses on anthropogenic climate changes (ACCs) while ignoring the internal climate variability (ICV) caused by the chaotic nature of ...

Surface temperature variability in climate models with large and small internal climate variability
Quarterly Journal of the Royal Meteorological Society, 2021AbstractBy analyzing large ensemble simulations using the Community Earth System Model (CESM_LE), the Max Planck Institute Earth System Model Grand Ensemble (MPI_GE), and Coupled Model Intercomparison Project phase 5 (CMIP5) climate models, we quantified internal climate variability (ICV) of surface temperature in each model based on the spread of ...

Internal variability of regional climate models
Climate Dynamics, 2001Two regional climate models have been applied to the task of generating an ensemble of realizations of the year 1982 with observed boundary conditions in areas covering parts of the Mediterranean countries. These realizations were generated by applying boundary conditions from the ECMWF ERA reanalysis project consecutively, carrying over the soil ...

AbstractTo better understand the role of internal climate variability (ICV) in climate change impact studies, this study quantifies the importance of ICV [defined as the intermember variability of a single model initial-condition large ensemble (SMILE)] in relation to the anthropogenic climate change (ACC; defined as multimodel ensemble mean) in global

Internal variability in regional climate simulations
2020<p>Following the huge increase in computer power over the past fifty years, it is now possible to conduct regional climate simulations at the convective-permitting (CP) scale (horizontal grid spacing O(1-3km)). Societal relevance is evident, as a large fraction of high-impact weather operates on these scales (e.g., intense summer

Climate variability and international trade
2023This paper quantifies the impact of hurricanes on seaborne international trade to the United States. Using geocoded hurricane data mapped to satellite tracking data for commercial ships, we identify hurricane intersections on sea-trade routes between U.S. and foreign ports.

Quantifying the Role of Internal Climate Variability in Future Climate Trends
Journal of Climate, 2015Abstract Internal variability in the climate system gives rise to large uncertainty in projections of future climate. The uncertainty in future climate due to internal climate variability can be estimated from large ensembles of climate change simulations in which the experiment setup is the same from one ensemble member to the next but ...

Internal variability in a regional climate model over West Africa
Climate Dynamics, 2007Sensitivity studies with regional climate models are often performed on the basis of a few simulations for which the difference is analysed and the statistical significance is often taken for granted. In this study we present some simple measures of the confidence limits for these types of experiments by analysing the internal variability of a regional

Atmospheric circulation internal variability contribution and global climate change
26th International Symposium on Atmospheric and Ocean Optics, Atmospheric Physics, 2020Local climate changes differ significantly from global trends and require tailored mitigation practices. Here, we analyze the surface temperature data from the network of meteorological stations in the Southern Urals and the numerical experiments over the period from 1979 to 2012.
