Technical Progress Report on the
Global Data-processing System for 2002
Country: Republic of Uzbekistan Centre: RSMC Tashkent
Several changes were introduced into the data-processing system in 2002.
2. Equipment used by the Centre
2.1 Computer types in use:
HP9000 Workstations - Volume of the disk subsystem:
9.3 x 2 gigabytes = Σ-18.6 gigabytes.
Operating system : HP-UX 10.0
Pentium-type personal computers using Intel processors (Pentium, Pentium
MMX, Pentium II, Pentium III)
Operating systems : MS Windows 95/98; NT; 2000; SCO Unix 5.04;
Linux RedHat 5.1
A4 matrix printers; A3 matrix printers; A4 black and white laser printers;
A4 colour laser printers; Colour ink-jet printers; A1 black and white plotters;
A1 colour plotters.
2.3 Data switching equipment
3. GTS data and products used
SYNOP, TEMP, PILOT, RADOB, GRID
4. Data entry system
5. Quality control system
Quality control for information issued by the Centre as maps is done visually. There is
no quality control for digital information.
6. Monitoring of the observing system
Monitoring of the surface data is carried out at the national level.
7. Forecasting system
7.1 System operation timetable and forecast ranges
Forecast results in GRID format are converted into forecasts for air routes,
which are disseminated among the Republic's main airports four times a day
7.2 There is no system for medium-range forecasts (4-10 days).
7.3 Short-term forecast system (0-72 hours)
7.3.4 Operational methods for the application of NWP products
In 2002 an automated system of NWP for air routes was introduced, based on
a Pentium PC, for the Republic's main airports. 0000 and 1200 UTC GRID
code data are used as outgoing data forecast information.
Air route forecasts include data on wind, pressure, geopotential and
temperature components in standard isobar areas, as well as data on
tropopause and maximum wind parametres.
8. Forecast product validity verification
Was not done.
9. Future plans
An automated system will be introduced from 2003 to 2005 for the calculation of
weather parameters in the free atmosphere, zones of heavy precipitation and
atmospheric fronts with a horizontal resolution of 75 kilometres on the basis of
regional hydrodynamic atmospheric models for Central Asia, using the workstation.
In 2003 an information base will be created in the PC for hydrodynamic atmospheric
modelling (reception, decoding and verification of GRIB code information, objective
analysis of weather parameter fields (geopotential, temperature, wind, humidity,
pressure at sea-level), archiving information in GRIB code format and synoptic data in
KN-01 code, and surface weather maps).
(Translator's note: KN-01 is the Russian original code name; it might stand for "kniga
nablyudatelya", which would translate as "observations registry" or "observations
