A glance at satellite images of the wintertime North Pacific Ocean shows great, <br />comma-shaped storms marching eastward, their tails arcing back southwestward toward Hawaii and beyond. These storms are redressing the imbalance between the warm tropics and cold <br />poles by creating an atmospheric conveyor belt. Cold air sweeps broadly southward behind the cold front that runs along the tail, and warm air is driven poleward along and just ahead of the <br />front. It is this warm and inevitably moist stream paralleling the front that has come to be known as an atmospheric river."</i><br /><br />The additional feature is the cold front associated with the cyclone should dip south of extratropical/tropical boundary so that the flow along the front can couple up with the tropical moisture.<br /><br />My hand-waving view is that you get this structure (the "hosepipe" or conveyor belt) between cyclones regularly but you only get an atmospheric river when the "hosepipe" is attached to a working faucet (the warm, wet tropical air)<br /><br />There are several (technical) papers and recording of presentations on http://tenaya.ucsd.edu/~dettinge/ the WX enthusiast might find interesting (particularly the ones about the Russian River flooding). The trick is to skip bits you don't understand then come back to them later (after reading around more).<br /><br />Western Wa is (probably) not going to get the rain this weekend. It's going into Vancouver Island and BC (see the plots). This is just an amazing example (white rainfall on the plot!) of what an atmospheric river can do. Of course if the river should move a little south ...Kevin Purcellhttps://www.blogger.com/profile/18157202870194603923noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-80479574465966959142010-09-24T07:57:29.343-07:002010-09-24T07:57:29.343-07:00I thought this winter was el niño, and last winter...I thought this winter was el niño, and last winter was la Nina.Chrishttps://www.blogger.com/profile/03328761480649487155noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-85366068918883328632010-09-24T07:05:43.846-07:002010-09-24T07:05:43.846-07:00Fellow Washingtonians, if you'll re-read Cliff...Fellow Washingtonians, if you'll re-read Cliff's words and graphics, you will see that the plume will hit "Northern and Central Vancouver Island and adjacent areas of BC."

But would I be wrong if I said that if an express event occured during La Nina, it most likely be during the early fall.<br /><br />If La Nina provides an active western pacific, warmer water in middle, and a stronger jet to carry that moisture pool across the ocean and high pressure inland, to me it seems like a perfect scenario.<br /><br />That would be a great research project.smokejumperhttps://www.blogger.com/profile/05358322512081660205noreply@blogger.com
