LJA current activity and data collection update

Posted in Lightning Jump Algorithm on by Kristin Calhoun.

This week has been a bit more active than we’ve seen in recent weeks… In fact, currently the storm in SW Oklahoma county just produced two lightning jumps (2021/2024 & 2030 UTC) about the same time that radar velocity indicated the start of a downburst…

Right panel shows tracked region selected at smallest scale (scale 0). Note: scale 1 & 2 were not tracking storms over the region due to size requirements. i.e., these storms were too small.
