A marked feature on the synoptic chart
earlier this week was the rather slow progression of the South Atlantic High.
Undercutting and overriding of airmasses and their intertwining flows will ensure vortex development identifiable for each successive 3-hourly synoptic chart
Quite naturally the full range of detail is expansive: and that is just the one synoptic chart
The synoptic chart
shows that an intense anticyclone has been present over the mid-Atlantic for the past week.
He also pioneered techniques for forecasting weather such as synoptic charts
, where weather observations taken at the same time were drawn on a map to aid forecasting - a technique still used today.
We obtained the synoptic charts
for 00 and 12 Greenwich mean time covering the period 1983-1995 on a daily basis from the archives of the European Meteorological Bulletin.
The text is enhanced by three important factors: the generous citation of sources, the use of synoptic charts
, and clear outlines of the various rites.
The most noticeable feature of the week's progression of synoptic charts
is that the core of the high pressure cells in the so-called subtropical high pressure belt, has shifted south by about one thousand kilometres.
This week's synoptic charts
were dominated by an anti-cyclonic circulation which persisted with its core over the Karas region for most of the week.
The main feature on all synoptic charts
for southern Africa this week was two low pressure systems, one on each side of the continent.
Four different synoptic charts
provide differing projections of this complexity, but each with a level of influence upon our weather.
The most noticeable feature of current synoptic charts
is that they consistently diverge from normal, expected patterns.
