Review:
Before readers become concerned about the location of this text
there are some very good reasons for reading on! If we look
at the number of really good introductory texts on the atmosphere
then we are reduced to a handful most of which are UK- or US-centric.
This is a pity for a variety of reasons. Firstly, the idea of
global warming suggests the need for a global appreciation of
the atmosphere. Secondly, the processes that seem common in
the Northern hemisphere are not so in the Southern. Put simply,
if we limit ourselves to models from just one area we fail to
appreciate the significance of phenomena elsewhere. For those
of us working in the Southern hemisphere the need for regional
texts is more immediate but perhaps it's also possible to appreciate
just how different the situation is here (the same goes for
ecology where it could be argued that the Northern hemisphere
paradigm doesn't always work South of the equator!).
The
book is divided into four parts. The first part looks at the
basics of atmospherics and global meteorology. Chapter one is
a good overview of the global atmospheric system. Chapter two
looks at the physical structure of the atmosphere and the energy
flows from both outside and within. This leads us to chapter
three which deals with the circulation patterns both globally
and within the region. To this point there is little that would
seem at of place. The text highlights key concepts and gives
some local variations where important. Part two changes scale
with a look at synoptic-scale phenomena. Thus chapter four start
with an examination of air masses and vertical stability i.e.
the temperature/moisture curves and the implications of these.
From the vertical we move to the horizontal with an overview
of winds and wind patterns both at ground level and in the upper
atmosphere. Chapter six describes local phenomena e.g. cyclones
and anti-cyclones which leads on to a major chapter on weather
systems. It's here that we get to see the real differences between
North and South. This is crucial because the systems that in
key areas of the environment e.g. Amazon, differ markedly in
their characteristics compared with those of Northern temperate
regions. Whatever the changes the next area is more familiar:
weather forecasting and a review of both practical and theoretical
perspectives. Chapter 9 is the first part of section three which
focusses on meso-scale phenomena such as frontal weather systems.
This is followed by a study of climates at both regional and
local scale. Part four is a study of climate change where the
two chapters look, respectively, at 'natural' climate change
through time and recent/future changes.
There
is much to recommend in this text. As an introductory book it
is clearly written, well illustrated and can deal with quite
complex issues relatively simply. If we then take the location
into account we find that it is one of the few books dealing
with the other half of the world! These two points alone make
it worthwhile reading but one must also add that it looks at
climatic phenomena either ignored or dealt with less fully by
other texts. Thus this text is ideal for those in the region
where it provides one of the best examples in its field. For
those living elsewhere but studying Southern hemisphere phenomena
this book is an ideal introduction which fills in many of the
gaps found elsewhere.
