1. Software Development.
• History.
SAWS has been developing visualization , database capture, Climate QC systems since
early 70’s.
• Developed by Meteorologists.
Almost all successful software systems were developed by Meteorologist software
developers. Large systems became unmanageable due to promotions and more often
resignations due to the IT boom in SA.
• Solution in the South African environment.
• Systems beeing developed became smaller.
• Exceptions METCAP (Norwegian Funds).
• Search for “of the shelf” products.
• Outsourcing large systems.

Workstation.
• 3.3 The NCAR radar software.
• 3.4 Development of MSG satellite display systems with European
Commission funds.
• 3.5 The Vaisala lightning display network.
• 3.6 Transfer of the NWP model from ETA to UNIFY Model.
Meteorological Data Capture System
Why develop this system inhouse?
• Developed with funds provided by the Norwegian Government (Nor-Aid
Program)
• Compiled detailed specifications and user requirements. A lot of
meteorological expertise available in weather observers and forecasters.
• Assemble a large development and maintenance team (10 persons)
• The need to replace the previous 20 year old system became critical due to the
fact that the developer retired. The old system were programmed in BASIC
and storing data in flat files. None of the current developers know BASIC.
• System Will Also be used by other SADEC countries.

System.
• Cooperation since the early 1970’s on ETA model
and RADAR (TITAN) software development and
maintenance.
• Bethlehem Precipitation Research Program –
Weather Modification REASEARCH.
• It was thru this program that the links with NCAR
and the “Raped Application development
Program” (RAP) really took off .TITAN SYSTEM
• South Africa became one of the first users of the “TITAN” sweet of
programs out side the US for real-time radar thunder storm,
identification, tracking and now-casting program developed by Dr
Michele Dixon (NCAR).
• The main features were the ability to look at the storm movement,
vertical storm structure, identification of new development and the
ability to control seeding aircraft on the same console. The South
African experts played a big roll in getting TITAN installed in Europe,
Canada, USA, Mexico, South America and the Middle East.
• Thru continues collaboration with NCAR on these fields’ mentions
above the South African Weather Service is in a world leading position
today. With the diversion of NCAR in many critical fields we hope
that we can keep the momentum of the past to keep up with the new
global issues for whish we all need the same answers. Recourses in
these fields are scares and needs to be shares.3 Discussion of a Few Large ICT SYSTEMS

– PCs running Linux OS
– Massively parallel computer systems (NEC
SX-series)
• Advanced scientific and technical
capabilities
• Available to universities and meteorological
institutes under a licencing agreementUM SA12 & SA15 Domains
XAANA
XAANJ
XAANGMet Office Collaboration
• Research tropical convection for better diurnal cycle that
feeds into cloud, precipitation and surface temperature
– (will need to build up expertise at the SAWS)
• Model sensitivity studies of vegetation/ surface type, soil
moisture, etc.
– (are these important to improve model analyses and forecast skill)
• Ground-truth verification of the UM over SA using RADAR
and station network
– (emphasis on case-studies to identify cause of forecast failure)
• DA OSE studies
– (must work with Met Office DA team to prevent duplication)
• WWRP/WMO Southern Africa severe weather forecasting
project input and using the UM in a short-range ensemble
forecast system and how a SREF could add value
