Hi Folks,
After a
one-week hiatus for the 32nd annual Northeastern
Storm Conference, Friday map discussion resumed on
focus was on the St. Patrick's Day
snowstorm that was impacting the
Northeast. Of interest was the zonally contracted
and meridionally
elongated trough responsible for the East
Coast development.
The following
images are attached to help support the discussion:
1. Maps of dynamic tropopause (DT) pressure (hPa) and winds (kt), and
sea level pressure (hPa) and 925 hPa
potential temperature from the
and 17 Mar, and 1200 UTC 16 and 17 Mar.
2. CONUS water vapor (WV) imagery from NCAR/RAP for 2345 UTC
15 Mar,
1145, 1745 and 2345 UTC 16 Mar, and 0445 and 1145 UTC 17 Mar.
3. Regional base reflectivity image for 0000 UTC 17 Mar.
4. KENX base reflectivity imagery 0458, 0557, and 0655 UTC 17
Mar.
5. ALB soundings for 0000 and 0600 UTC 17 Mar.
6. Plotted surface observations from NCAR/RAP for 0300, 0600
and 0900
UTC 17 Mar.
7. NCEP/NAM initialized 850 hPa analysis
for 0600 UTC 17 Mar.
8. NCEP/GFS initialized 300 hPa analyses for 0000 and 1200
UTC 16 and 17 Mar.
9. Precipitable water (PW) imagery for 0931 and 2118 UTC 16
Mar. and
0936Z 17 Mar from
http://amsu.cira.colostate.edu.
The DT/925 hPa
maps and GFS 300 hPa analyses show that the
storm occurred in conjunction with the
development of a zonally
contracted and meridionally amplified trough
that took on a negative
tilt. The subsequent trough amplification
allowed for the tapping of
a tropical moisture plume (see
attached PW imagery) that was in place
over the
region (valuers
> 35 mm) was located ahead of a slow-moving
subsynoptic scale DT disturbance that formed via
fracture from a PV
tail over the western and central US
between 12-14 Mar. As this
fractured DT disturbance moved eastward across
responsible for triggering several mesoscale
convective systems
(MCSs) over
eastern and southern
the Gulf coast and over the northern
aforementioned tropical moisture plume.
Trough
development and amplification was also accompanied by
flanking upstream and downstream ridge
amplification. The signature
of this trough/ridge development and
evolution, seen very nicely in
the attached WV imagery, was *not*
typical of classic downstream
development. Earlier in the week (Tu) the GFS ensemble forecasts for
Fri/Sat exhibited what appeared to be relatively large
uncertainty in
conjunction with the forecast eastern
coastal storm. Solutions ranged from no
storm, a weak storm going
well out to sea, a moderately intense
storm along the coast and a
storm tracking well inland along the
Restaurant potpourri of solutions. It is likely that regional GFS
predictability was below average for this event at
the 72-96 h time
scale. If this conjecture is confirmed by
subsequent model skill
numbers the event is worthy of further
investigation for this reason
alone.
A noteworthy aspect of the storm development was the absence
of a coupled jet structure in the upper
troposphere. Instead, the
developing cyclone and elongated precipitation
shield was confined to
the right-entrance region of the
downstream 300 hPa jet. This
downstream 300 hPa jet remained quite
meridionally amplified during
the 36 h development period ending 1200
UTC 17 Mar, suggestive of a
possible role for diabatic heating in
downstream jet maintenance.
The attached
KENX radar imagery surrounding 0600 UTC 17 Mar,
NCAR/RAP surface maps for 0300, 0600 and 0900 UTC 17 Mar, the
0000
and 0600 UTC 17 Mar ALB soundings, the
0600 UTC 17 Mar NCEP/NAM 850
hPa analysis, and the appended metar obs show the following:
1) The precipitation shield was highly elongated along the
coast
(consistent with the PW imagery).
2) An intense thermal band was present at 850 hPa across
southern New
3) This intense thermal band sloped NW with height based on the
0600
UTC 17 Mar ALB sounding.
4) The surface low propagated NNE along a moderately intense
coastal front.
5) The surface low deepened modestly at best and was just
under 1000
hPa at 1200 UTC 17 Mar.
6) Mesosclae precipitation band
development was evident just to the
south and east of ALB a few hours on
either side of 0600 UTC 17 Mar.
Higher base reflectivities in this
band may also be a partial result
of sleet mixing in with the snow as
stations NE/E/SE of ALB
(
all reported a changeover from snow to
sleet (no question, however,
that the highest snowfall
totals.....22-24".....occurred just to the
south and east of ALB).
7. A complex surface frontal structure existed over eastern
New
km, reported a 10 C temperature
difference near 1200 UTC 17 Mar as
the low steered NNE along the coastal
front. Likewise, a second, and
weaker, thermal boundary marked by a wind
shift from ENE to NNW was
located in the colder air over eastern MA
(LWM,
Scientific
issues raised by the 2007 St. Patrick's Day storm
include (figure them out and you will be a
candidate for "sainthood"
or an all-expense paid trip to STL) the
following:
1. What were the antecedent conditions that led to the
formation of
the zonally contracted and meridionally
amplified trough? What rule
did the flanking ridges play in the
formation process? How do these
ridges develop and why do they often seem
to develop in tandem? Can
the zonally contracted and meridionally
amplified trough be viewed as
a trapped feature within a larger
scale developing ridge?
2. The trough-ridge development scenario did not correspond
to
classical downstream development. Is this
difference important for
atmospheric predictability and if so why? Is
there any evidence that
atmospheric predictability is lowered in these
situations?
3. What would a global climatology of zonally contracted and
meridionally amplified troughs reveal? Anecdotal
evidence suggests
troughs of this type are more common in the
SH as compared to the NH.
If true, what does this say about the trough development
process and
what role do the flanking ridges play?
4. Do longitudinally contracted and meridionally elongated
slow-moving troughs facilitate the extraction of
tropical moisture
into higher latitudes and lead to heavy
precipitation events on the
forward sides of these troughs? What happens
when there is a
bonus-added extra in the form of a southern
disturbance with embedded
convection available to interact with
meridionally amplifying and
zonally contracting trough?
5. Are zonally contracted and meridionally amplified troughs
associated almost exclusively with downstream
upper-level jets
instead of meridionally coupled jets, given
that the east-west scale
of the trough is too short to support a
southern jet where the flow
is appreciably subgeostrophic in the
base of the trough?
6. Are zonally contracted and meridionally amplified troughs
more apt
to be favored in late winter and early
spring when the circulation is
spinning down as opposed to the autumn when
the circulation is
spinning up? Can these kinds of troughs be
viewed as one type of
precursor for cutoff cyclone development?
7. Can the model of left-of-track precipitation associated
with
landfalling and transitioning tropical cyclones
when a downstream
upper-level jet is present be applied to zonally
contracted and
meridionally amplified troughs? If so, what role
does diabatic
heating play in downstream ridge building
and jet development,
especially when a tropical moisture surge is
present on the forward
side of the trough as occurred with the
St. Patrick storm?
8. Are these kinds of troughs dominated by jet-entrance dynamics
strongly modified by latent heat release? Is
the strong and elongated
downstream jet just a signature of diabatic
heating? Are these
structures the cool season equivalent of warm
season landfalling and
transitioning TCs? Is the left of track
precipitation in the St.
Patrick's Day storm analogous to left of track precipitation
in the
right entrance region of an upper-level
jet during the landfall and
extratropical transition of Hurricane Floyd
(1999)?
