Laura Suárez-Gutiérrez is a PhD student at the Max Planck Institute for Meteorology, in Hamburg, Germany, as a member of the International Max Planck Research School on Earth System modelling. Her main research interest is the evaluation of the role of internal variability in the climate system. The work presented at EGU 2017 corresponds mostly to research performed as a master student under the supervision of Prof. Dr. Jochem Marotzke, at the Max Planck Institute for Meteorology. To evaluate the long-standing question of what dominates the differences between observed and simulated amplification of tropical warming aloft in the troposphere, the awarded poster presents a comparison between different radiosonde records and the MPI-ESM 100-member large ensemble simulations of tropical tropospheric warming trends. This comparison shows that discrepancies in tropospheric warming trends are dominated by large remaining observational uncertainty and chaotic internal variability, rather than by systematic errors in model performance.
