Hi @david_lexicon Does the home screen not show the charts? [image: 1766843237878-screenshot-2025-12-27-134653-resized.png]

@david_lexicon I would use MADIS. https://madis-data.ncep.noaa.gov/public/sfcdumpguest.shtml

@david_lexicon It seems that the sea salinity has an effect on climate, in particular on the evolution of the temperature at a very large scale. But not on short- or medium-term temperature variations. If you have different information, please let us know. Windy visualises weather forecasts but no climatological outlook. Meteorology and Climatology must not be confused.

@david_lexicon Clouds in light yellow are those with low tops. It also has to do with sun angle. https://community.windy.com/topic/11608/reflection-of-the-sun-on-satellite-pictures Not to be confused with dust-sand storms, they look more brown.

Thank you for your reply. For Windy to have archives, it needs a lot of funding that is for sure.

@hypnos Hi, the layers are already described here - [image: 1588589629095-screenshot-2020-05-04-at-12.52.06.png]

Thanks for your reply. I have to take notice of what happens to air masses at different levels.
