Isobars...

Hi, why do use only 2 hpa between the Isobars, all the other's use 4 hpa.

Using 2 hPa intervals between isobars provides greater detail in pressure variations, helping to identify finer weather features like weak pressure systems or subtle gradients. However, most use 4 hPa for simplicity and readability.

The difference between Windy and the usual surface analysis maps is that in Windy you can zoom in and the 2 hPa intervals help to see the isobars field at high zoom level.

I don't think hPa can be used much, just 2 can show you more detail on pressure variations
