WEATHER FORECASTING

Weather Forecasts are issued to save lives, to reduce property damage, to reduce crop damage and to let the general public know what to expect. Weather Forecasting is the most important service of RMC Karachi. The RMC Karachi provides Weather, Climate Forecasts and Warnings for Sindh Region. The responsibility of issuing Regional Forecast for Sindh was given to Meteorological Watch Office (MWO), Karachi (under RMC Karachi). Different kinds of Forecasting Tools such as Satellite & Radar images, various NWP models, Meteorological charts (Surface, Pilot, Temps, Change of (Pressure & Temperature) Charts etc) and Current Data etc are used for daily weather inference and forecast. The current and forecasted meteorological information are used for different activities in the region as Agriculture, Tourism, Irrigation, Aviation, Industries, Construction, Oil exploration and Research purpose etc. These information can also be used to mitigate the weather related hazards like Dust Storms, Heavy Rains, Flooding, Thunderstorms, Droughts and Heat Waves etc.

WEATHER FORECASTING TOOLS

  1. Weather Observations

    • Surface Data
    • Satellite Data
    • Radar data
    • Wind Profilers
  2. Weather Analysis

    • Data communications, storage, processing, display, analysis and weather pattern
  3. Numerical weather predication (Atmospheric Models)

    • Using current and past observations to predicate weather in near future Equations describe how atmospheric temperature, pressure, winds, and moisture change with time. The models are programmed into the computer.
  4. Numerical weather predication (Atmospheric Models)

    • Using current and past observations to predicate weather in near future
    • Equations describe how atmospheric temperature, pressure, winds, and moisture change with time. The models are programmed into the computer.
  5. Prognostic Chart (Prog)

    • The final forecast chart representing the atmosphere at a specified future time. A forecaster uses the Prognostic Charts as a guide to predicting the weather. A good forecaster needs to know model limitations: A personalized practical interpretation of model outputs local geographic features.
    • The Meteogram is a chart that show how one or more weather variables has changed at a station over a given period of time.
    • Vertical Profiles of temperature, wind, and RH
