Backing vs Veering Winds (misuse of terms?) | Stormtrack A veering wind with height in the lower part of the atmosphere is a type of directional shear often considered important for tornado development -- Also, could someone clearly explain exactly why there is more convergence with backing vs veering winds
Veering vs. Backing winds | Stormtrack As a reminder, veering winds with height implies warm-air advection, while backing winds with height (or a backing wind profile) implies cold air advection Typically, in the US, we want to see a veering low-level wind PROFILE (so, veering with height) with a backing surface wind tendency It's also pretty common to see backing winds with height in the mid and upper-levels, which can be
Veer-back - impacts of backing aloft in supercells | Stormtrack Definition of veer-back (-veer) VBV refers to a backing of the winds in a layer above another layer with veering winds, and sometimes bounded above by another layer with veering winds (hence the second -veer in the name) The image below illustrates this feature:
Have question regarding veering backing and the cyclonic rotation of . . . veering and backing are terms used for the wind changing at a certain level, but can also be used to explain how winds change with height, as you've said The terms were originally just for surface winds, where they either veered or backed around the compass Supercells derive their rotation from the tilting of horizontal vorticity into the
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!
Backing Winds ? | Stormtrack Please explain "backing winds" and their significance in tornadogenesis and chase planning stratagies I thought veering winds were more important but read a lot about backing winds in some TA discussions Thanks
Plotting Storm Motion on a Hodograph | Stormtrack When high 0-6km shear speeds, with more directional veering at the tropopause, storms often don't really make 300mb until way down stream So these storms often move more, well, 'backed' when starting You see a lot of good days with initial storm vectors of like 190@40, then it gets mature and goes 210@40 Might even speed up a smidge
Backing vs Veering Winds (misuse of terms?) - Stormtrack The word "veering" on its own means the wind is changing in a clockwise direction, and "backing" means it is changing in a counterclockwise direction The actual definitions of the words are simple and contain nothing about easterly vs westerly or height or time
Backing Winds | Stormtrack Backing winds also refers to a counterclockwise turning in the wind with height A backing wind profile from the surface to 500mb is indicative of cold air advection (CAA) Warm air advection (WAA) creates a veering profile, or a clockwise turn with height When winds back at the surface, they become more easterly, allowing a stronger veering profile from surface to upper-level, more
