For how many days in advance, weather forecasts are currently issued by IMD in DAMU Project?
Show Hint
The DAMU and GKMS agro-advisory services are based on medium-range weather forecasting, which is standardly issued for a 5-day period twice a week in India.
Step 1: Understanding the Concept:
The India Meteorological Department (IMD) implements agricultural advisory services under the "Gramin Krishi Mausam Sewa" (GKMS) scheme.
The District Agro-Meteorological Unit (DAMU) project was established under this scheme to provide localized, sub-district scale weather forecasts and crop advisories directly to farmers. Step 2: Detailed Explanation:
Weather forecasts can be classified by their time horizon:
Short-range forecast: Valid for up to 72 hours (3 days).
Medium-range forecast: Valid from 3 to 10 days.
Long-range forecast: Valid for more than 10 days (seasonal or monthly).
The DAMU project is designed to provide medium-range weather forecasts.
Under this project, the IMD generates and issues localized forecasts twice a week (usually on Tuesdays and Fridays) for a period of 5 days in advance.
These 5-day forecasts include parameters such as rainfall, maximum and minimum temperatures, relative humidity, wind speed, wind direction, and cloud cover.
These medium-range forecasts allow agricultural scientists and extension workers to prepare and distribute timely, crop-specific advisories to help farmers plan operations such as sowing, irrigation, fertilizer application, and pesticide spraying. Step 3: Final Answer:
Under the DAMU project, weather forecasts are currently issued 5 days in advance.
