Walker Cell doing a number on our Blob
Posted by JAC on 8/6/2009, 7:49 am
WV shows the subisidence zone ahead of our blob is still intact. It looks like the anti-cyclone up-draft zone has redeveloped just west of Panama. This has squashed a good part of the convergence associated with the blob. QSCAT, 850mb vorticity, and MIMIC-TPW have all weakened considerably. The LL Convergence map shows that it will be moving into strong downdraft zone soon. Also seeing a strong UL convergence zone ahead as well. It is a bit of a mystery to me why convection continues to fire except that it currently is in the end of the diurnal max phase this morning. I don't see a lot of shear or mid-level vorticity to fire off an MCS. Maybe, this is a dryline type effect where there is a huge lapse-rate gradient.    |
