Correct option is B
The correct answer is (b) Jammu
Explanation:
- In September 2021, Union Minister Dr. Jitendra Singh inaugurated an X-Band Doppler Weather Radar at the Indian Meteorological Department (IMD) office in Jammu.
- This installation aimed to enhance real-time monitoring and forecasting capabilities for severe weather events such as thunderstorms, lightning, squalls, and heavy rainfall in the Jammu region.
Information Booster:
- Purpose of the Radar: The X-Band Doppler Weather Radar provides nowcasting capabilities, offering very short-range forecasts (up to 3 hours) to detect and monitor severe weather events promptly
- It contributes to improved weather services, including better forecasts for agriculture, tourism, and disaster management in Jammu and Kashmir.
- As of December 2024, 39 Doppler Weather Radars (DWRs) are installed at various locations across the country.
- The S-band radar provides a radial coverage of 400 km, whereas C-band and X-band provide 250 km and 100 km, respectively.
Doppler Weather Radars (DWR) - Quick Overview
- Principle: Based on the Doppler effect, which measures the change in frequency of the radar signal due to motion, allowing for precise weather monitoring.
- Key Components:
- Parabolic Dish Antenna: Focuses and transmits radar signals.
- Foam Sandwich Spherical Radome: Protects the radar equipment from weather elements while allowing signals to pass through.
- Functions:
- Rainfall Intensity: Measures the intensity of rainfall.
- Wind Shear and Velocity: Tracks changes in wind speed and direction.
- Storm and Tornado Detection: Locates the center of storms, tornadoes, or gust fronts and monitors their movement.
- Applications: Used for precise weather forecasting and surveillance, particularly for tracking severe weather events like storms and tornadoes.
