Hi, I am working on a personal project and I am using forecast provided by meteo.pl . More precisely I am using their API: https://devmgramapi.meteo.pl/meteorograms/um4_60 ( Unified Model on a 4 km grid up to 60 h) and it returns JSON in response (you can check example JSON and Excel table here ). And as the title says I don't know what storm_max and flash_max columns mean. The response says their unit is just "1" . All I know is that they relate to storm and lightning intensities. I really would like to know their ranges so I can somewhat classify them into distinct levels like "small/medium/high intensity" . I have gathered some of their responses last year over 3 months and the maximum storm_max value was 40 and maximum flash_max value was 10. But I don't know if those are their true maximums. I couldn't find any information online so I am asking here.
