Climate: Past, Present & Future

Andrea Schneidereit

Andrea Schneidereit is a scientist at the German Weather Service (DWD) and one of the core developers of the ICON‑XPP configuration for eXtended Predictions and Projections, contributing to both seasonal forecasts at DWD and CMIP7 simulations that feed into international assessments including the IPCC reports. She has experience with both low- and high-resolution configurations and specializes in the troposphere–stratosphere interplay, a challenging atmospheric region that many models still do not represent accurately, despite its critical role for long-term climate simulations. Her research focuses on coupling between atmospheric waves and mean flow, and the representation of stratospheric dynamics in ICON-XPP.

When small-scale turbulence imprints on the global atmospheric circulation: Uncovering the Cause of the Double Intertropical Convergence Zone Bias in ICON

One feature stands out in any map of tropical rainfall from satellites: a narrow band of intense precipitation encircling the globe near the equator. This is the Intertropical Convergence Zone, a key feature of the global atmospheric circulation that imports moisture into the tropics and exports energy to higher latitudes. But for decades, climate models have struggled to simulate this feature cor ...[Read More]
