To prevent users from being overwhelmed by lightning detection alerts, we set up a rule that our software follows: for each lightning strike, an alert is sent if it’s been more than 30 minutes since the last alert or if it’s closer than the previous strike.
Could you add a 3rd consideration to those rules? I was getting alerts every 2-3 minutes as things moved closer. That’s just too many.
So, some sort of maximum alerts per time period, or perhaps looking at how much closer each time? Also, another threshold when it’s within (maybe) 2-3 miles?
Is there a measurement for the length of a lighting discharge, and if it’s cloud to ground or cloud to cloud?
Hi @chinatablet Thanks for the ideas. Best to post to https://community.weatherflow.com/c/owners/feature-requests so we can capture and discuss. The little lightning sensor in the AIR will measure approximate distance, but it’s not super accurate which is why the distance values are presented in range buckets. It’s really designed to notify you of approaching storms and increasing/approaching intensity. Detects both cloud-to-ground and cloud-to-cloud energy.
Sorry. It seemed more appropriate to put “ideas” with the current discussion.
So under “ideal” ionospheric conditions a sky wave could enable the unit to pick up lightning a lot more distant than the sensor’s rated distance, similar to VHF ducting in the troposphere?
Since I believe that the Franklin chip is listening at extremely low frequencies, I would assume that it was more like AM radio skipping off of the ionosphere than VHF tropospheric ducting.
For lightning detection at a distance, you may want to look at the Blitzortung.org descriptions:
Unfortunately, getting one of their devices is a multi-year wait. I’ve been on the list for two years, and have only moved up to #2,700 out of almost 6,000 people waiting…
I just checked and my rank is:
Your request is ranked at position 3541 of 5790 .
Thanks for the explanation, and as for Blitzortung, yup have been watching the evolution for some time, and actively use the map to compare the strikes to my WF since I got it. Today was the first time I actually saw lightning data reported on my station that was not in range, but appreciated, I used to be a CB (citizens band) user and as a kid that was what got me interested in radio , Cheers
I got my Blitzortung station after about two years.
It operates from Galway, on the west coast of Ireland.
In case anyone is interested, it must be a cold day in Hades (and a hot day in Anchorage, Alaska) because I just received the long-awaited email that I am finally at the top of the Blitzortung list and can order the kit!
Ironically, there’s a thunderstorm moving in right now, almost as if mother nature is taunting me…
I moved closer too. I was at 3541. Now I am ranked at position 2231 of 4978 . So maybe in 9 months I can order one.
My request is ranked at position 2231 of 5107.
Still at 2231 but 129 more have signed up.
