Tuesday convection meetings

Meetings with a focus on convection will take place every Tuesday between 10 and 11. Speakers can prepare a topic they are working on or a paper for discussion, which will take up most of the hour, with some time left for other business.

The idea is not to make a too formal presentation, but rather bring a few plots and talk about those. The aim will be to improve out understanding of the physics of convection, become more familiar with the literature on this topic, and stay updated on the research in our own group. Another topic for a meeting would be the parameterizations at the Met Office and ECMWF.

See below for a list of papers that could be discussed. Please send any suggestions for additional reading material to me.
