TRR 181 Seminar "Microscale atmospheric modeling: Challenges and opportunities" by Juan Pedro Mellado Gonzalez (Universität Hamburg)

The TRR 181 seminar is held by Prof. Juan Pedro Mellado Gonzalez on November 18, 11am.

Abstract

Long-standing biases in weather and climate models are often rooted in the meteorological microscales, particularly in the planetary boundary layer. Recent advances in measurements and simulations are providing further insight into these scales and their coupling to mesoscales and synoptic scales. Moreover, these advances guide the development of new parametrizations for the next generation of weather and climate models, where kilometer-scale resolution represents a change of paradigm compared to the last fifty years. In this talk, we will review some of these advances, focusing on high-resolution simulations. We will consider three topics that remain particularly challenging, namely, near-surface effects on scaling laws and flow organization, entrainment at the top of the planetary boundary layer, and the role of cloud microphysics in the evolution of cloud-topped boundary layers.
