4 comments on “Continental Supercells vs. Maritime Supercells

  1. Reblogged this on Folmercast and commented:

    I just wrote this blog entry for work that discusses some new satellite products that will help us detect the most severe thunderstorms!

  2. Hi michael – by what analysis standard is the ocean thunderstorm a supercell ?
    If the OPC were to have issued some sort of thunderstorm message, what would the lead time have been before the intense part of it’s lifecycle ?
    Was there a total lightning “jump” of significance in the ENI or any other total lightning data ?

    • Brian – OPC does not currently distinguish among convective modes (something that is trying to be pushed now), but rather just a binary yes/no analysis. You can diagnose this storm as a supercell due to the isolated nature, the concentrated core seen on satellite (and further supported by the OTD and Lightning products), and the fact that it was moving right of the mean flow which as low to mid levels was southwest (seen on ASCAT, but not shown for the post). OPC does not currently issue dedicated thunderstorm messages, but this is being looked into for future implementation, therefore lead-time would be a complete guess at this juncture. We don’t have access to “total lightning data”, only the GLD-360 feed. Outside of the LMAs, how else would you get total lightning in this remote area?

      • OPC has access to total lightning data from Earth Networks Inc. via a contract with NWS.

        The data accessed via a web page called streamer RT. If OPC does not have the login information, have them contact me or check with WPC.
