Wind currents in the Earth’s equatorial stratosphere change direction every 26-28 months. Abundances of ozone, methane, water vapour, and other trace atmospheric gasses oscillate on the same timescale. This phenomenon is known as the “quasi-biennial oscillation” (QBO) and also occurs on other solar system planets (Jupiter and Saturn), though with different periods. It occurs becauseContinue reading “Stratospheric wind and water vapour fluctuations on tidally locked exoplanets”
I was invited to give a 10-minute PhD lightning talk at the Edinburgh Women in Space Conference from 26-28 March 2021. Here’s the talk, with a brief non-technical overview of recent exoplanet science and my research.
A little while ago my kitchen sink had a serious clog. The emergency plumber worked on it for two hours. After failing to clear it with the manual plumbing snake and the much larger, electric plumbing snake, he finally tossed in the towel and poured a bottle of 80% sulphuric acid (chemical formula H2SO4) downContinue reading “Water cloud, acid cloud, iron cloud”
