FUNCTIONS OF ORGANIZATION
Major functions entrusted to the Pakistan Meteorological Department are as under:
To provide information on meteorological and geophysical matters with the objective of traffic safety in air, on land and sea, mitigation of disasters due to weather and geophysical phenomena, agriculture development based on climatic potential of the country, prediction and modification of weather forecast.
(Detail at Annexure-I)
In pursuance of its objectives the department has established:
a) A network of observing stations to generate meteorological, geophysical and phenological data.
b) A telecommunication system for speedy dissemination of data.
c) Meteorological offices to analyse data for issuing forecasts and warnings for aviation, agriculture, shipping, sports, irrigation etc.
d) Climatological and data processing units for scrutinizing, comparing and publishing data for appraisal of long term weather trends and earthquakes.
Existing network of met observatories is given at Annexture-II.
ACHIEVEMENTS
The Pakistan Meteorological Department, at the time of its establishment in 1947, inherited only 15 Meteorological Observatories from the Central Meteorological Organization then operating in the Subcontinent. The Department with its continuous efforts has improved weather forecasting capabilities by expanding the network of meteorological observatories, developing methods of observation, improving telecommunication facilities and forecasting techniques.
The major achievements of the Department are introduction of modern flood forecasting system, earthquake and nuclear explosion detection system, radar, satellite, computer technology, flight safety consultancy services in seismic design of dams, buildings and other development and disaster relief schemes.
The Department has also played vital role in research work and its scientists have made valuable contribution. More than 300 scientific papers have been written and published in both national and international scientific journals. Major emphasis in the research has been laid on the field of artificial rain making, ground water detection, arid zone research, ozone measurements, solar energy, wind power potential, oceanographic and space research.
Many of the Research Organizations such as Arid Zone Research Institute (AZRI), Space and Upper Atmospheric Research Corporation (SUPARCO), and Pakistan Atomic Energy Commission (PAEC) started their functioning with the initial assistance of the Pakistan Meteorological Department. Meteorological services are extended on regular basis to Civil Aviation Authority (CAA), Federal Flood Commission (FFC), Pakistan Agriculture Research Cuncil (PARC),Ministry of Environment and Ministry of Food & Agriculture.
The Department processes the raw data and issues Meteorological forecasts and warnings used by various user agencies details of which are given in Annexure-III.

EXISTIG HUMAN RESOURCE PRACTICES
The recruitment on technical and administrative posts is carried out in accordance with approved recruitment rules and prevailing Government policies. Being the scientific department the proportion of administrative posts is very low as compared with scientific staff. All administrative cadres ranging from BPS-19 to BPS-5 carry only 5% of the total sanctioned strength.
The total manpower working in all grades and cadres is 2180. at present, there are 1965 sanctioned posts in BPS-1 to BPS-15 irrespective of their technical/administrative cadre. In officers cadre (both technical/administrative) the sanctioned strength is 215 in BPS-16 and above. The detailed analysis of available human resources is given in Table-1 and Table-2.
NETWORK OF VARIOUS DISCIPLINES OF PAK. MET. DEPARTMENT
A brief description of the operational offices of Pakistan Meteorological Department included in the above mentioned organizational setup is given below.
1) FLOOD FORECASSTING DIVISION LAHORE (FFD)
This centre was established in 1978 with the collabration of UNDP. The operations of this centre are backed by the following components.
a) EXTRA-ORDINARY RAINFALL AND DISCHARGE MEASUREMENT SYSTEM:
This system is operating under the administration of WAPDA. For this purpose, Rim stations have been setup by WAPDA in catchment areas of river INDUS at " Kachura" which measures the snow melting and inflow through the station. The instruments are installed at Bishma, Ogi, Phulra, Tarbela and Daggar which read the flow rate and take into account the rain element. All these informations are collected by WAPDA and passed on to the National Flood Forecasting Bureau (NFFB) Lahore through its 36 telemetry centers. The second type of discharge data of canals is collected by the Irrigation Department through its own network; utilizing police department facilities, data is passed on to NFFB Lahore.
b) QUANTITATIVE PRECIPITATION MEASUREMENT (QPM) RADAR.
This radar, with the wavelength of 5.3 CM is installed at Sialkot. It detects the position of clouds and precipitation within the radius of 230 Kilometers. This radar also covers 17 catchment areas of rivers. Another Doppler Radar is installed at Lahore which provides quantitative and three dimentional precipitation data in catchment areas of main reservoirs.
c) COMPUTER CENTRE
After the data have been received from the concerned quarters, it is feeded into the computers which are installed at NFFB Lahore. The data is processed after every six (6) hours and based on the analysis, flood forecast report is produced daily for the concerned agencies.
2. AGROMET CENTRES IN PAKISTAN
Pakistan, being an Agricultural country, requires sufficient and accurate agromet data. Keeping in view this responsibility, a National Agromet Centre at Islamabad and four Regional Agromet Centres at Quetta, Tandojam, Faisalabad and Rawalpindi were set up in the first phase of a UNDP sponsored project. These are fully functional now. This WMO/UNDP project is a part of an overall scheme to study meteorological factors in relation to crop production. This aims at maximizing the production and minimising the crop damages associated with the meteorological phenomena. Apart from these Centres, a forecasting office for agriculturists has also been established at Islamabad. This Centre named, National Agromet Centre (NAMC) issues necessary forecasts for the benefit of farmers and other related agencies. Main objective/functions of National and Regional Agromet Centres are described as under
2.1 National Agromet Centre (NAMC), Islamabad.
