Climate sensitivity

Analytical insights into the transient climate response (preprint) [Article webpage]

B. Chtirkova
Published in ArXiv, 2026

Solving the heat equation with energy conservative boundary conditions for linearly increasing forcing to understand the transient climate response and the trend in top of atmopshere imabalnce.

Atmospheric shortwave radiation

Persistent Extreme Surface Solar Radiation and Its Implications on Solar Photovoltaics [Article webpage]

G. Senger, B. Chtirkova, D. Folini, J. Wohland and M. Wild
Published in Earth's future, 2024

An exploration of persistant high and low radiation events of relevance for photovoltaic power generation and grid planning.

Shortwave Radiative Flux Variability Through the Lens of the Pacific Decadal Oscillation [Article webpage]

B. Chtirkova, D. Folini, L. F. Correa and M. Wild
Published in Journal of Geophysical Research: Atmospheres, 2024

Motivated by the observed correlation between the Pacific Decadal Oscillation index and observed downwelling shortwave radiation trends in Europe and the United States, we perform numerical simulations with ICON-A to investigate the dynamical pathway which links sea surface temperatures to cloudiness over remote regions.

Internal Variability of the Climate System Mirrored in Decadal-Scale Trends of Surface Solar Radiation [Article webpage]

B. Chtirkova, D. Folini, L. F. Correa and M. Wild
Published in Journal of Geophysical Research: Atmospheres, 2023

We link trends in known climate modes of variability to trends in downwelling surface shortwave radiation. We use this information to hypothesize whether internal variability had an enhancing or suppressing effect on observed radiation trends at certain locations.

Internal Variability of All-Sky and Clear-Sky Surface Solar Radiation on Decadal Timescales [Article webpage]

B. Chtirkova, D. Folini, L. F. Correa and M. Wild
Published in Journal of Geophysical Research: Atmospheres, 2022

We explore all possible statistically insignificant trends of downwelling shortwave radiation for a given location that can occur due to internal variability given a Gaussian distribution and zero autocorrelation in time.

Geothermal Convection and Double Diffusion Based on Profiling Floats in the Black Sea [Article webpage]

E. V. Stanev, B. Chtirkova and E. Peneva
Published in Journal of Geophysical Research: Oceans, 2022

Deep Argo float data traces the sinking of the Bosphorus plume and reveals signatures of geothermal convection.

Interannual Change in Mode Waters: Case of the Black Sea [Article webpage]

E. V. Stanev and B. Chtirkova
Published in Journal of Geophysical Research: Oceans, 2022

Mixing pathways in the Black Sea observed from Argo floats.

Climate Change and Regional Ocean Water Mass Disappearance: Case of the Black Sea [Article webpage]

E. V. Stanev, E. Peneva and B. Chtirkova
