Animation weather system (gif)

I completely forgot to follow up on that !
Since I’ve made a couple of animations made from a composite analysis of many such weather systems (atmospheric rivers).

Using -JG for integrated vapor transport :

Global view of the composite over the Pacific ocean. The Inter-Tropical Convergence Zone (ITCZ) can clearly be seen, as well as the mid/high latitude of water content build up

Using -JL for integrated water volume :

Same idea, with a Lambert conic projection and a different dataset. The colormap is “logarithmic”. I also added winds anomalies at 350hPa (high atmosphere)

(Code excerpt)

gmt end

gmt movie main.sh -Sbpre.sh -Sfpost.sh -N${tmpdir} -C20cx20cx120 -Tindex.txt -Iinclude.sh -Pb -D11 -Fmp4 -M97

Hope this help :slight_smile:
