Backing vs Veering Winds (misuse of terms?) - Storm Track A veering wind is a wind that turns clockwise with height An example of a veering wind would be a southeast wind at the surface and a west wind at 700 millibars A veering wind is associated with warm air advection and dynamic lifting Backing winds are indicative of cold air advection which would be sinking air
Veer-back - impacts of backing aloft in supercells | Stormtrack This touches on the questions I had (veering backing winds with height vs cyclonic anticyclonic hodo curvature and at what height the kink negatively impacts supercell behavior) After getting hosed by veer-back on April 26 and May 8 last year I'll definitely be paying more attention to 0-3km SRH and hodo curvature
Have question regarding veering backing and the cyclonic rotation of . . . I'm working my way through Tim Vasquez' book Severe Storm Forecasting There was a section regarding veering and backing that got me thinking So veering is obviously a clockwise change with height (or distance, or time), and backing is a counterclockwise change with height (or distance, or
Veering vs. Backing winds | Stormtrack On many occasions I have heard these terms used to describe potential positive or negative factors for a tornadic situation Now that I understand what each means, am I correct in assuming that, in general, veering winds with height and backing winds at the surface would be the preferable scenario?
Veering (backing) winds and WAA (CAA) | Stormtrack Is WAA (CAA) always associated with veering (backing) winds or are there circumstances in which this relationship doesn't hold? I assume the tropics, being highly barotropic, wouldn't see such a relationship but the midlatitudes would due to the high baroclinicity Thanks!
Great Lakes Drylines - Stormtrack What is striking is the abrupt drop in dewpoints, and again, the veering of surface winds There have been other big tornado days associated with drylines in the Great Lakes region There have been other big tornado days associated with drylines in the Great Lakes region
Measuring Shear | Stormtrack It's easy to see on a hodograph that you can still have a UNIDIRECTIONAL shear profile even if you have a veering wind profile Most people see se sfc winds at sw flow aloft and think supercells, but that profile can also be one of unidirectional shear (and thus less favoring of cyclonically-rotating supercells)
State of the chase season 2020 | Page 11 | Stormtrack The more I look at Saturday the more I think it could be a pretty decent day Good veering wind profile and H5 winds even pushing 40kts in KS along with big instability GFS continues to want to displace the moisture farther east from the dryline Not sure how much I buy that Again, it will be
Meters squared per second squared: What the heck. . . ? In example 2, the placement of the axis is not so apparent to me You've got winds veering 180 degrees with height Now, if you had only the upper and lower winds, which are blowing in opposite directions, then I could understand why the axis of rotation would remain horizontal as you've shown
Vorticity | Stormtrack If the vertical shear profile is unidirectional (which does NOT require that the wind profile be unidirectional -- a nice veering wind profile can still produce a straight-line hodograph and undirectional shear), there is no streamwise vorticity unless until storm motion deviates off the hodograph, which will then result in a turning of the
