- 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
- 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:
- 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
- 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
- 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!
- Why does Cold Air Advection cause backing winds with height?
And, I suspect that the answer will also tell why Warm Air Advection causes veering winds with height I’ve seen this mentioned In multiple basic meteorology resources, but I haven’t seen an explanation of the physics that causes it, and I haven’t been able to intuitively imagine a hypothesis
- HP Supercells w Tornadoes | Stormtrack
I was just curious as to why back veering winds cause HP supercells? Seems all 2015 has been for the most part And this seems to happen a lot And how does it affect tornado potential from the storm?
- Vorticity | Stormtrack
In what situations would a veering wind profile produce a straight-line hodograph and unidirectional shear? Would wind speeds have to actually be slower the higher up in the atmosphere you go? There's a great figure in the Markowski and Richardson Mesoscale book to highlight this (Fig 2 13), but I can't find it online
