Studying the origin of Venus' clouds with numerical modeling

Hiroki Karyu will give a seminar entitled "Studying the origin of Venus' clouds with numerical modeling".

This seminar is organised by the ELI-C (Earth and Climate) division of the Earth and Life Institute.

Hiroki Karyu is working at Tohoku University (Japan). He is part of the Planetary Atmospheric Physics Group, in the Department of Physics.

Abstract

Clouds play a fundamental role in shaping planetary climates, and their formation is dependent on the presence of nm-scale particles that act as seeds. In the Venusian atmosphere, the properties of these cloud seeds have remained poorly constrained. To address this, we have developed a detailed cloud model simulating the initial stages of the seed and following cloud formation. Our simulations place new constraints on the characteristics of the cloud seeds, thereby providing a quantitative characterization of the particles that initiate the formation of Venus' global cloud layers.
