@Jacko-Jaxon These scales both for Thunderstorm and for Rain accumulation are correct. l/km2 means lightning per square kilometre. Could you imagine 1 lighting per square metre? (It’s not litres per square kilometre) Rain accumulation can be the accumulation of rain over 10 days and 1m (1000mm) is not a non sense ! This is possible in tropical regions as shown here some weeks ago: [image: 1604391998533-2828e413-24b0-4e7a-bc90-158e0531478b-resized.jpeg]
