@Gkikas-LGPZ Hi, thank you for detailed report. I put this bug in our internal issue tracker for maps. We are not able to generate new maps "on-demand", but we will fix this in the next release of the base map along with some other bugs.
I hope that this major step forward initiated by ECMWF will push other institutes and groups, like Meteo France, to be engaged in the same type of move to share much more data for free, via maps and charts. Of course, GRIB files are another story,...
One of the typical feature of a medicane is the hot core which is much warmer than outside. It is very interesting and instructive to follow it at different levels. At the beginning, you could notice the difference at low levels, 850 hPa for instance but day after day, you can see the differences, in the core and outside, also at much higher levels. This is because in the development process of an hurricane, the system releases latent heat, among others because of the condensation of warm and humid air at higher and higher level. Here you can see it clearly on the follwing map at 600hPa : +2°C in the core, -2 or -3°C outside. Huge difference !
Very instructive to follow the development of this medicane
Ouch, such a global resolution would be a bit better than 0.01° (1111m at 0° Lat), i.e. 100x360x100x180 = 648 M cells/grid for each parameter/level.
To be compared to current global weather forecast model GFS 0.25° (1 M cells/grid).
I guess displaying grids of such a model on public web applications should also wait for future high-speed internet cables and hardware :o)))
