the last time i regularly vlogged was my video series documenting my phd studies which finished in 2017 oh my god but as you'll see in this video not a huge amount has actually changed from what i was up to back then i'm going to show you what my life was like today a wednesday which is pretty representative of what i get up to most of the time the...

Questions & Answers

Q: What is Claude, and what is its purpose?

Claude is a climate model written in Python, designed to create videos that explore atmospheric physics and address questions about the Earth's atmosphere. It aims to make climate modeling more user-friendly and accessible.

Q: What are the challenges the modeler faces in fixing Claude?

The modeler faces two main challenges: addressing issues related to convection, which involves vertical movement in the atmosphere, and dealing with boundary representation, particularly at the poles, where latitude-longitude grids are not effective.

Q: How does the modeler address the issue of boundary representation near the poles?

Instead of using latitude-longitude coordinates, Claude employs a polar plane method, which involves using cartesian grids placed on the north and south poles. This approximation allows for calculations on a regular grid, with the results then merged with the latitude-longitude representation.

Q: How does the modeler spend their day before the livestream?

The modeler spends their day fixing issues in the code, particularly focusing on the discontinuity at the boundary caused by advection calculations. They work between different files, coordinating the core calculation file, the basic library file, and the complex physics application file.
