QUARTERLY ACHIEVEMENTS OF INDIA METEOROLOGICAL DEPARTMENT INDIA METEOROLOGICAL DEPARTMENT Volume : 1, No. 3, Jul Sep 2010 1 OBJECTIVES OF MODERNISATION Modernisation of atmospheric observation & forecasting systems was initiated to improve the quality of meteorological services in the country with focus on the following: To enhance capabilities of observational systems To network all existing and new observational systems To enable reception, processing and archival in digital form To assimilate multi sector data in numerical models and prediction To ensure realtime dissemination of all processed information As a part of this and in keeping with the guide–lines given by the Planning Commission, Secretary, MoES constituted an expert committee comprising of eminent scientists and experts in India under the chairmanship of Shri D. R. Sikka to specify the optimum requirements of the observational network required for Forecasting, Aviation Services, Agrometeorology and human resource in the field of meteorology to provide a weather service of World Standard. The committee recommended the optimum observation network for IMD.

In the first phase, it was approved to develop a network with minimum and necessary observation system consisting of existing and new instruments, appropriate connectivity with a complete endtoend forecasting system along with High Performance Computing (HPC) for receiving, processing and archiving information at IMD Headquarters as well as their dissemination in real time to the end users in digital form. In next phases further densification of the observation network is to be undertaken. The commissioning of Doppler Weather Radars will start from the first phase but all 55 DWRs will spill over to 12 th five year plan as Phase III. The Union Cabinet approved the implementation of Modernisation of observation and forecasting facilities of IMD (Phase – I) on 13 th December 2007, (to improve the weather forecasting services in India) at an estimated cost of Rs.920.00 crores in two years. It has been further extended till March 2011 The PhaseI to be implemented in project mode and classified into broadly two groups: a) OBSERVATIONAL SYSTEMS 1. Doppler Weather Radars 2.

Subsequently, it withdrew from the entire northwest India including Delhi on 28 September. The forecast of withdrawal of monsoon from Delhi was very crucial in view of the ongoing work pertaining of the Common Wealth Games (CWG), which was to be organized from 314 October, 2010 in Delhi. IMD generates and issues operational extended range forecast on every Friday for subsequent two weeks. The multimodel extended range forecast is prepared based on the coupled model outputs from ECMWF and NCEP. The ECMWF has a specific monthly forecast system, which has 51 ensemble members. The products of the ECMWF monthly forecasting system are based on weekly forecasts for 4 weeks based on every Thursday and valid for days 511 (week1; Monday to Sunday), days 1218 (week2), days 1925 (week3) and days 2632 (week4). The operational coupled model run at NCEP, known as the Climate Forecast System (CFS) generates the forecast on every day with 4 ensemble members. The outputs from these two models are used for generating the multimodel ensemble forecast, which is generated on every Friday with forecast anomaly for week 1 (Monday to Sunday) and week 2 (subsequent Monday to Sunday). The operational extended range forecasts generated on 9 September, 2010 as given in Fig. 3 indicate continuation of rainfall over northwest India and Delhi region till 26 September and thereby no chance of monsoon withdrawal till that time. Thus, there was indication of no withdrawal of monsoon at least till 26 September about 17 days in advance, which was very useful information for the CWG2010 organizers. The operational coupled model run at NCEP, known as the Climate Forecast System (CFS) generates the forecast on every day with 4 ensemble members. The outputs from these two models are used for generating the experimental multimodel ensemble forecast through the following steps. Figs. 3(a&b).

  NETWORKING, ANALYSIS AND DISSEMINATION   

Meso‐scale (WRF) high resolution analysis and forecast  The  regional mesoscale analysis system WRF‐Var  is operationally  running  in  IMD Head Quarter, Delhi with  its all components  i.e. preprocessing programs  (WPS and REAL), observation assimilation program  (WRF‐Var), boundary condition updation  (update_bc) and forecasting model (WRF).   In WRF‐Var assimilation  system, all conventional observations over a domain  (200S  to 450N; 400E  to 1150E), which merely covers RSMC, Delhi region are considered to improve the first guess of GFS analysis. Assimilation is done with 27 km horizontal resolution and  38  vertical  eta  levels.  The  boundary  conditions  from GFS  forecasts  run  at  IMD  are  updated  for  consistency with  improved mesoscale analysis. WRF model is then integrated for 75 hours with a nested configuration (27 km mother and 9 km child domain) with full physics (including cloud microphysics, cumulus, planetary boundary layer and surface layer parameterization). The real time WRF‐Var analysis wind at 850 hPa at 9km during 17‐20 September, 2010  is shown  in Fig. 1,  indicating system formation  in Orissa coast  and  subsequent  northwestward  movement.  Heavy  rainfall  observed  over  many  parts  of  western  UP  and  Uttarakhand associated with  the  system.  The  observed  cumulative  rainfall  and  the  corresponding  forecast  cumulative  rainfall  from WRF‐Var associated  with the system during the period 17‐20 September 2010 is shown in Fig. 2.  It is seen that model reasonably captured heavy rainfall in 24hr, 48hr and 72hr forecast also.

In  addition  to  the  core  instruments,  the NOAA  satellites  also carry:  7.  Solar  Backscatter‐Ultraviolet  Radiometer  (SBUV/2),  a 

spectral radiometer with 12 channels in the 252.0‐322.3 nm  in  discrete mode  and  160‐400  nm  in  scan mode, used for generating total ozone and ozone profiles.  

8.  Moderate  Resolution  Imaging  Spectroradiometer (MODIS)  is  a  payload  on  board  the  Terra  and  Aqua satellites.  The  instruments  capture  data  in  36  spectral bands  ranging  in wavelength  from  0.4  µm  to  14.4  µm and at varying  spatial  resolutions  (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km).  

 The  usability  of  the  products  ranges  from  NWP  model assimilation,  nowcasting,  aviation  forecasts,  land  surface processes  its  atmospheric  interaction,  energy  flux  exchanges, radiative  transfer,  global  energy  budget,  cloud  categorization, ozone  concentration  variations,  radiation  heat  budget,  Global circulations,  fish  stock  locations,  etc.    Few  of  the  products  are provided below: Fog Detection 

Normalized Difference Vegetation Index (NDVI)

   

Modernization of Cyclone Warning Dissemination System  In  continuation  with  the  meeting  under  the  chairmanship  of Shri A. K. Bhatnagar, ADGM(EREC) on 20.8.2010 between  IMD, ISRO, Doordarshan; Shri A. K. Sharma, Scientist F, (Sat. Met.) and Shri N.  K.  Pangasa,  Scientist  E  (Telecom)  represented  IMD  for finalisation of an MoU with ISRO for DTH modified type Cyclone Warning  Dissemination  systems  installation  (500  nos.)  along coastal India, in a meeting  with  ISRO and  M/s BEL Ltd. officers on 31.08.2010.

AUTOMATIC WEATHER STATIONS AND RAIN GUAGES  

AWS and ARG Installations  As  the  automated  systems  can  be  installed  in  a  uniform  grid enabling  for a better numerical model  ingest, 550 Numbers of AWS  and  1350  ARGS  were  to  be  installed.    The  installed locations  are  provied  in  the  MAP  as  a  red  dotted  overlay.  Tabular details of  installations made upto 30th September,2010 in each state is also provided.   

Installed AWS (550 Project)

   

Installed ARGs (1350 Project)

The  latest  statistics  of  the  number  of  stations  state  wise  is provided below :   List of AWS & ARG Installed till 30th September 2010  STATE  AWS Installed

 AIRPORT MET SYSTEMS 

 Modernisation of 26 airports with state‐of‐art aviation weather support  system has been proposed under modernisation plan. CST for this has been completed and the case is being processed further with MoES.  

WIND PROFILER  SYSTEMS  Four wind‐profilers under modernization plan and  three under CWG were  planned.  Tropospheric wind  profilers  at  Allahabad, Mangalore, Balasore, Machilipatnam, New Delhi, and Boundary layer wind‐profilers at Jaipur and Agra have been proposed . CST for  this  has  been  completed  and  the  case  is  being  processed further with MoES.  

 SATELLITES  NOAA/MODIS/Metop  receiving  and  processing  systems  were installed  at  New  Delhi  and  Chennai  for  generating  satellite derived products from Polar orbiting satellites of USA & Europe and to use them in conventional forecasting  and NWP models.
