  1. Some lovely radar echoes heading straight for me just now. :clap:

    They will probably head in your direction after they pass through here.

    The temp on the coast is 0.6C, with a cold NWly breeze blowing off the land.

    The wind aloft is increasingly more easterly and less northerly than earlier, helping the showers come ashore further up the coast. North Dublin, Meath, and possibly south Louth, may get some showers soon.

    All white here in Stamullen now :yahoo:

    What site you using for the radar Brig?

  2. Can someone explain to me what the "CloudSat Reflectivity Zw" is / what it means etc...I dont know I've never seen it before =\

    I dont claim to fully understand it all but here is what my understanding of it is. It's an estimate of the absorption loss of the observed reflectivity and it's measured in the mm^6 per m^3. It doesnt operate like a normal weather radar that mainly looks for rain. This measures the actual clouds also.

  3. Hello all,

    My first post on this great forum that I've been following for a while now. I've been glued to following the storm seasons since 2004 and I've been trying to learn more about these as I go. This forum is certainly helping that, and hopefully I can contribute something back over time.

    Bill's cloud tops seem to be getting really really cold now, i presume that's because they are close to the top of the troposphere (17km?) by now.
