AtmosBlock

AtmosBlock detects and classifies atmospheric blocking in 500 hPa geopotential (Z500) fields, deterministically, and offers a web portal to run the analysis on ERA5 reanalysis data on demand.

It has two parts:

• FAST-IBAN: the scientific core, written in C with OpenMP and MPI. It finds candidate highs and lows by sampling each point along great circles and classifies Omega and Rex patterns.
• The portal: a React web client and a NestJS API, backed by Python services that download ERA5 from Copernicus, run FAST-IBAN and draw maps.
