Hi,
Wonder if it would be possible to allow users to select the gap between isobars. Many of us are more used to 5 mb or 10 mb gaps. At a quick glance 2 mb gaps can be terrifying for an offshore sailor.

Hi, your remark is right when you zoom out (synoptic view) but Windy allow to focus on small areas and in this case a gap of 2 hPa is useful.
At least a possibility to change to 4 hPa would be OK (WMO recommend 4 or 5 hPa and e.g. the Met Office use 4 hPa). That’s 1 isobar for 2 on actual Windy maps. -
I'd like to support this recommendation as well.
An option to choose 5 hPa or 4 hPa distance would be great! -
@rahra
What's the usefulness? -
It is that most pressure charts use 5 hPa distance.
If one is used to look at and read such charts it may be disturbing to look at the Windy isobars because it suggests much higher wind speeds. This is because of the isobars being more dense.
Of course it isn't really more wind because of the 2 hPa distance but it looks like.Regards,

My support for this feature. I'd also prefer the 5hPa distance.
-
This recommendation is also one I would like to support. It would be great if we could choose between 5 hPa or 4 hPa distance.

It is possible for users to select the gap between isobars (the lines on a weather map that connect points of equal pressure) in some weather forecasting software and apps. This feature is typically found in advanced weather forecasting software and apps that are geared towards professional meteorologists or marine navigators.

Hello, what exactly do you mean? You can view forecast between each isoline gaps.

@Vents1981
Selecting a fixed pressure difference between isobars, for instance 4hPa or 5hPa, makes it possible to estimate the ratio of the pressure to the distance, and consequently to estimate the wind force.
Visually it is a very rough estimate or a little more precise with an abacus like this one which must take into account the latitude.
Nowadays with weather models that accurately predict the wind speed, I don't see what would be the benefit to have a chosen pressure gap between isobars.

@andoca
Thermals forecasts are already available in Windy. Just select this layer if you want it.
And what is the connection with “Isobars” which is the subject of this thread? -
I agree when you zoom out (synoptic view)
-
What are isobars?

@LexieMark
lines connecting points of equal atmospheric pressure (reduced to sea level on the maps).
