Lightning strike data over sat comms?
Hi All,
Apart of the tools available to us in my occupation we have access to 'Weatherzone' lightning strike data. this is a great tool in near real time lightning tracking, and I believe it would be majorly beneficial to a cruiser in a lightning prone area.
My question is can you get this data in some kind of GRIB, or other compressible format that can be sent over iridumGO or similar? even a refresh of data every 15min you could tell which direction and if the cloud is strengthening.
I'm in Australia, and can subscribe for $6/month, but cant see if you can get the data in a smaller file format...

i use windy.com / weather radar. One can animate 2 or 6 or 12 hours, it shows also lightening strikes. Priceless, one of the all time best softwares
if these predictwind guys could incorporate this into their app, including cloud animation would be just amazing.

Re: Lightning strike data over sat comms?
As with everything corporate, with the version of weatherzone I use I can zoom right in to our position and monitor what is around our local area so totally agree its a great tool
However unless you have a 4G connection you can access this information, so wondering if it is available in a compressed format that can be sent over satellite, in the same way as a GRIB is sent/received.

I see thunderstorms and weather radar choices on Windy, but not lightning strikes. What option is that?

Re: Lightning strike data over sat comms?
just curious, but what sensors exist that can track individual strikes locations with great accuracy?
Even if they existed and were fielded what good does it do you to know that a strike occurred at a location? it’s not like we can see it coming and move out if it’s way?

Being forewarned of nearby lightning, enables time to prepare, such as disconnecting & storing portable electronics in our Faraday cage.

Re: Lightning strike data over sat comms?
Use your best available sensors, your eyes and your ears. Flash, 50 seconds, boom, that's ten miles and you are now in range for a strike. Anything less than 50 seconds flash-boom and you are under the gun.
I use WeatherTap.com, which shows microbursts and their projected paths, and what cells are likely to become tornadoes. It will do individual strikes, but it's really only good for determining that a front that is coming does or does not contain lightning. Your eyes and ears are real time sensors.

Re: Lightning strike data over sat comms?
What do golf courses us to determine when to shut down? I have a suspicion it has something to do with ionized air?

And, if you don't hear the boom, you got hit.

Re: Lightning strike data over sat comms?
Although not showing lightning strikes directly, the CAPE index shows where lightning is likely. A CAPE index of 1000 means lightning strikes are unlikely. A CAPE index of greater than 3500 means lightning is highly likely. Its not perfect, but is is available as part of the Grib data set.

Re: Lightning strike data over sat comms?
Sferics....
many years ago an instrument called Strikefinder was popular in GA aircraft. It would plot strikes real time on the instrument's face and leave the indication there to fade over some short time...you could see where the storm cells are
I wonder if something like that would work on a boat? I'd actually be a bit surprised if such a thing doesn't exist for marine applications.
If it would work a person could probably grab an old strikefinder on ebay from someone upgrading their panel

I won one of these on CF but I can’t test it till the upcoming season.

Select weather radar. If you do nothing will see ligtening strikes as they happen with couple seconds delay. If you choose to animate 2, 6 or 12 hours you get the history including strikes. See here i marked one lightening 11 hours ago. Instrumental for dodging lightening areas if you have internet.
