So to make an idealized continent like Africa I just took a standard CLM input file and replaced the area approximately over North Africa
with the zonal average values of West Africa (where the Sahara is the hottest).
However, using National Centers for Environmental Prediction − National Center for Atmospheric Research (NCEP - NCAR) reanalysis data (41), Petoukhov et al. (34) showed that, during a number of recent NH extremes in July and August, certain persistent high - amplitude atmospheric wave patterns with barotropic vertical structure evolved, to which the quasistationary component of midlatitude barotropic free waves
with zonal wave numbers k ≈ 6 − 8 made an exceptionally large contribution.
1a designates the amplitude of the 15 - d running means of the external thermal + orographic barotropic forcing
with zonal wave number m at the EBL, averaged over the midlatitude belt Δ = 37.5 ° − 57.5 ° N.
These waves
with zonal wave numbers k ≈ 6 − 8 (they can be noninteger; we will call these waves k waves) usually experience strong meridional dispersion, and, for that reason, their energy disperses rapidly.
A strong snowmelt in late April / early May and torrential rains in late May / early June could have been caused by the occurrence of persistent quasibarotropic high - amplitude QRA structures
with zonal wave numbers m = 6 and m = 7 in the field of the NH midlatitude meridional velocity.
All of the necessary conditions for the QRA event were met for the free wave
with zonal wave number k ≈ 7.05 within the midlatitude waveguide whose boundaries are marked by the vertical solid lines in B.
All of the necessary conditions for the QRA event were met for the free wave
with zonal wave number k ≈ 6.8 within the midlatitude waveguide whose boundaries are shown by the vertical solid lines in B.
Our study shows that, in boreal spring - to - autumn 2012 and 2013, a majority of the weather extremes in the Northern Hemisphere midlatitudes were accompanied by highly magnified planetary waves
with zonal wave numbers m = 6, 7, and 8.
34 can favor an onset of midlatitude quasiresonant amplification (QRA) of these waves, causing a strong increase in the atmosphere's dynamical response to quasistationary midtroposphere external forcing
with zonal wave numbers m = 6, 7, and 8 (Calculation of the Meridional Wave Number).
Here we show that a considerable part of these extremes were accompanied by highly magnified quasistationary midlatitude planetary waves
with zonal wave numbers m = 6, 7, and 8.
The necessary conditions for QRA were met for the quasistationary free wave
with zonal wave number k ≈ 6.8 within the midlatitude waveguide (see Fig. 3B).
40, the barotropic orographic and thermal forcing
with zonal wave numbers m is the major extratropical source for forced quasistationary barotropic dynamical waves with these zonal wave numbers.
Free extratropical Rossby waves
with zonal wave numbers about 6 to 8 mostly occur as high - amplitude, fast traveling waves (the so - called synoptic transients responsible for much of the weather variability in the extratropics); once established, they can freely propagate predominantly to the east with a phase speed c ≈ 6 − 12 m ⋅ s − 1 without maintenance from external forcing.
Petoukhov et al. (34) proposed a common mechanism for generating persistent high - amplitude quasibarotropic planetary - scale wave patterns of the NH midlatitude atmospheric circulation
with zonal wave numbers m = 6, 7, and 8 that can explain a number of the major NH summer extremes over the 1980 — 2011 period (34, 35).
In contrast to these fast traveling waves, the quasistationary extratropical barotropic free waves
with zonal wave numbers 6 to 8 are normally weak, with a magnitude of the meridional wind velocity less than 1.5 — 2.5 m ⋅ s − 1 (25, 34, 35, 39, 40).
The zonal component of the thermal wind shear is in accord
with the zonal distribution of temperature.
Previous works (eg Moron et Plaut 2003) find an El Nino influence on European fall - winter weather,
with a zonal mode dominant on nov - dec (warm and wet flux from Atlantic) and with a higher probability of a switch on west blocking or Greenland anticyclone regimes on feb - march.
It is essentially a zonally symmetric structure, but
with a zonal wave three pattern superimposed.
Poleward eddy momentum fluxes interact
with the zonal mean flow to sustain latitudinal displacements of the mid-latitude westerlies (Limpasuvan and Hartmann, 2000; Rashid and Simmonds, 2004, 2005).
CB & DM really need some boost on quality presence... Some beast in front back four & versatile CB if we still gonna play
with zonal marking, some pacey like kos could boost our back confident... Realize how bad mert is, he is not leader material for our back but Kos is the only one..
Have a feeling we are doing away
with zonal marking.
With zonal marking nobody has any responsibility, which suits Wenger as he doesn't like to blame anyone for anything.
Especially
with zonal marking.
Man marking is very easy and gives EVERY player in the team responsibility whereas
with zonal marking it's always a case of «It wasn't my fault».
What's wrong
with zonal marking?
That's what you get
with zonal marking — no responsibility whatsoever.
With zonal marking last season we conceded once in the league u obviously watch allot of match of the day as they always comment on arsenal zonal marking even when theirs nothing to comment on
Learnt two things, our defence can't cope
with Zonal marking, and we really need a strong DM.
Not exact matches
You say (and I agree) «Defending 101, STAY
WITH YOUR MAN» but as we play the pathetic
zonal marking rubbish no one in the team has any RESPONSIBILITY for stopping any of our opponents!
Sanchez was in the second line of defence in a
zonal system and his job was to block runners, not to go
with them — Hangeland ran through him and it was for Kos to pick him up.
Wow the article is about man marking or
zonal coverage and we have Man U Liverpool and directness why bother
with the articles.
Can't we try out a mix of man - marking +
zonal if not comfortable
with man - marking.
If Bould is doing such a good job why are we still playing
zonal defense?!? I'll tell you why — because anyone who disagrees
with our cancer of a manger will be left without a job.
There's no way in a million years that Bould would persist
with this failed system of «
zonal marking» on set - pieces.
I wish this
zonal marking crap would be done
with, or at least get some players to mark man for man.
His return allowed Arsene Wenger to play a midfield trio
with a rare quality: three players who could pass, tackle and cover for each other in each midfield role, a sentiment supported by
Zonal Marking's tactical piece about the game.
