Local and Remote Forcing Factors of Heatwave in India -A Reanalysis and Adjoint model based study
Abhirup Banerjee, Armin Koehl, Frank Lunkeit +1
Continental heatwaves can dramatically impact ecosystems and societies, e.g., by leading to excess mortality, wildfires, and harvest failures. With a warming climate, their impacts…
Resonant excitation of Kelvin waves by interactions of subtropical Rossby waves and the zonal mean flow
Katharina M. Holube, Frank Lunkeit, Sergiy Vasylkevych +1
Equatorial Kelvin waves can be affected by subtropical Rossby wave dynamics. Previous research has demonstrated the Kelvin wave growth in response to subtropical forcing and the re…
A new diagnostic tool for water, energy and entropy budgets in climate models
Valerio Lembo, Frank Lunkeit, Valerio Lucarini
This work presents a novel diagnostic tool for studying the thermodynamics of the climate systems with a wide range of applications, from sensitivity studies to model tuning. It in…
Climate Sensitivity to Carbon Dioxide and Moist Greenhouse threshold of Earth-like planets under an increasing solar forcing
Illeana Gomez-Leal, Lisa Kaltenegger, Valerio Lucarini +1
Carbon dioxide is one of the major contributors to the radiative forcing, increasing both the temperature and the humidity of Earth's atmosphere. If the stellar irradiance increase…
Climate sensitivity to ozone and its relevance on the habitability of Earth-like planets
Illeana Gomez-Leal, Lisa Kaltenegger, Valerio Lucarini +1
Atmospheric ozone plays an important role on the temperature structure of the atmosphere. However, it has not been included in previous studies on the effect of an increasing solar…
Stable equatorial ice belts at high obliquity in a coupled atmosphere-ocean model
Cevahir Kilic, Frank Lunkeit, Christoph C. Raible +1
Various climate states at high obliquity are realized for a range of stellar irradiance using a dynamical atmosphere-ocean-sea ice climate model in an Aquaplanet configuration. Thr…
Can we use linear response theory to assess geoengineering strategies?
Tamas Bodai, Valerio Lucarini, Frank Lunkeit
Geoengineering can control only some climatic variables but not others, resulting in side-effects. We investigate in an intermediate-complexity climate model the applicability of l…
Reconsidering the relationship of the El Niño--Southern Oscillation and the Indian monsoon using ensembles in Earth system models
Mátyás Herein, Gábor Drótos, Tamás Bódai +2
We study the relationship between the El Niño--Southern Oscillation (ENSO) and the Indian summer monsoon in ensemble simulations from state-of-the-art climate models, the Max Planc…
Fluctuation Analysis of the Atmospheric Energy Cycle
Richard Blender, Denny Gohlke, Frank Lunkeit
The atmosphere gains available potential energy by solar radiation and dissipates kinetic energy mainly in the atmospheric boundary layer. We analyze the fluctuations of the global…
The role of atmospheric greenhouse gases, orbital parameters, and southern ocean gateways: an idealized model study
Eileen Hertwig, Frank Lunkeit, Klaus Fraedrich
A set of idealized experiments are performed to analyze the competing effects of declining atmospheric CO2 concentrations, the opening of an ocean gateway, and varying orbital para…
Predicting Climate Change using Response Theory: Global Averages and Spatial Patterns
Valerio Lucarini, Frank Lunkeit, Francesco Ragone
The provision of accurate methods for predicting the climate response to anthropogenic and natural forcings is a key contemporary scientific challenge. Using a simplified and effic…
Crisis of the Chaotic Attractor of a Climate Model: A Transfer Operator Approach
Alexis Tantet, Valerio Lucarini, Frank Lunkeit +1
The destruction of a chaotic attractor leading to rough changes in the dynamics of a dynamical system is studied. Local bifurcations are characterised by a single or a pair of char…
The Impact of Oceanic Heat Transport on the Atmospheric Circulation: a Thermodynamic Perspective
Alexander Schröder, Valerio Lucarini, Frank Lunkeit
The present study investigates how global thermodynamic properties of the climate system are affected by the changes in the intensity of the imposed oceanic heat transport in an at…
A new framework for climate sensitivity and prediction: a modelling perspective
Francesco Ragone, Valerio Lucarini, Frank Lunkeit
The sensitivity of climate models to increasing CO2 concentration and the climate response at decadal time scales are still major factors of uncertainty for the assessment of the l…
Global instability in the Ghil-Sellers model
Tamas Bodai, Valerio Lucarini, Frank Lunkeit +1
The Ghil-Sellers energy balance model of Earth's climate, features -- for a considerable range of the solar intensity -- two stable climate states (a warm and a cold snowball Earth…
Thermodynamics of Climate Change: Generalized Sensitivities
V. Lucarini, K. Fraedrich, F. Lunkeit
Using a recently developed formalism, we present an in-depth analysis of how the thermodynamics of the climate system varies with CO2 concentration by performing experiments with a…
Thermodynamic Analysis of Snowball Earth Hysteresis Experiment: Efficiency, Entropy Production, and Irreversibility
Valerio Lucarini, Klaus Fraedrich, Frank Lunkeit
We present an extensive thermodynamic analysis of a hysteresis experiment performed on a simplified yet Earth-like climate model. We slowly vary the solar constant by 20% around th…
