    What is Wayanad’s new X-band Radar?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Doppler, X-Band Radar, NISAR

    Why in the News?

    After the floods and landslides in Wayanad in July 2024, the Union Ministry of Earth Sciences approved the installation of an “X-band radar” in the district.

    What is an X-Band Radar?

    • An X-band radar is a type of radar that operates in the 8-12 GHz frequency range of the electromagnetic spectrum, with wavelengths of 2-4 cm.
    • This radar is particularly useful for detecting smaller particles like raindrops, fog, and other fine materials due to its shorter wavelengths, which allow for higher resolution images.

    Key Features of X-Band Radar:

    • High Resolution: The shorter wavelength provides more detailed images, making it ideal for tracking weather phenomena, including precipitation and particle movements.
    • Limited Range: They have a relatively shorter range compared to other types like S-band radars because higher frequency signals get attenuated (weakened) faster as they travel through the atmosphere.

    Applications: In weather forecasting, X-band radars are used for short-range weather monitoring, such as predicting rainfall intensity and landslides. They are also used in air traffic control and military applications.

    What is a Doppler Radar?  

    • A Doppler radar is a type of radar used primarily in meteorology to measure the velocity and movement of weather formations, such as clouds and storms.
    • It works on the principle of the Doppler effect, which refers to the change in frequency of waves as their source moves relative to the observer.

    It’s applications: 

    • Velocity Measurement: By measuring these changes in frequency, Doppler radar can determine how fast the object (e.g., rain cloud) is moving and in which direction.
    • Weather Monitoring: Doppler radar helps in tracking rainfall intensity, detecting wind patterns, and predicting the formation of storms or tornadoes.

    India’s Radar Network

    • The India Meteorological Department (IMD) began using radars in weather applications in the 1950s.
      • The first indigenously designed X-band storm detection radar was installed in 1970 in New Delhi.
    • In 1996, the IMD replaced 10 outdated X-band radars with digital X-band radars.
    • India’s radar network includes both wind-finding and storm-detecting X-band radars. The country also uses S-band radars (2-4 GHz) for long-range detection. The first S-band cyclone detection radar was installed in Visakhapatnam in 1970.

    Recent Developments:

    • In September 2024, the Ministry of Earth Sciences announced that India would install 56 additional Doppler radars over the next few years.
    • On September 11, 2024, the Union Cabinet approved the ₹2,000-crore ‘Mission Mausam’, which aims to upgrade meteorological infrastructure, including the installation of up to 60 radars by 2026.
    • The Wayanad radar initiative also includes the installation of a C-band radar (4-8 GHz) in Mangaluru, with an observational range of 250 km.

    About the NISAR

    • NISAR, short for NASA-ISRO Synthetic Aperture Radar, is a joint satellite mission being developed by NASA and ISRO.
    • NISAR will use radar imaging to create a high-resolution map of the earth’s landmasses, tracking changes in natural processes.
    • Its payload consists of an L-band radar (1.25 GHz, 24 cm) built by NASA and an S-band radar (3.2 GHz, 9.3 cm) built by ISRO.
    • NISAR is expected to launch in 2025 aboard an ISRO GSLV Mk II rocket, with a total cost of $1.5 billion, primarily funded by NASA.

    China’s ‘Anaconda Strategy’

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Anaconda Strategy

    Why in the News?

    Taiwanese authorities recently stated that the People’s Liberation Army (PLA) is using an ‘anaconda strategy’ to put pressure on Taiwan.

    China’s Military Maneuvers around Taiwan

    • China has been steadily increasing its military activities around Taiwan, both by air and sea:
    1. Air incursions into the Taiwan Strait have increased significantly, from 36 incursions in January to 193 in September.
    2. Chinese ships operating around Taiwan has also risen, from 142 in early 2024 to 282 by August.
    • These maneuvers seem designed to wear down Taiwan’s navy and air force, creating constant pressure.

    What is the Anaconda Strategy?

    • The ‘anaconda strategy’ involves a combination of military tactics, psychological pressure, and cyber warfare.
    • The goal is to weaken Taiwan’s defenses and force the island into submission without the need for a full-scale invasion.
    • China’s approach is one of relentless pressure.
    • It is trying to tire out Taiwan and force it into making mistakes, which could then be used as a pretext to launch a blockade.
    • Its ultimate goal appears to be to make Taiwan vulnerable without resorting to direct military conflict, keeping Taiwan’s forces on the defensive.

    Other Unconventional Strategies used by China:

    • Wolf Warrior Diplomacy: A confrontational and assertive style of diplomacy used by Chinese officials, characterized by aggressive rhetoric and nationalistic stances, often aimed at defending China’s interests and countering foreign criticism.
    • Gray-Zone Tactics: A set of covert strategies that fall between war and peace, including actions like cyberattacks, propaganda, and incremental territorial gains, aimed at advancing a nation’s goals without triggering a full-scale military conflict.
    • Salami Slicing: A strategy where small, incremental actions are taken over time to achieve a larger goal without triggering a strong reaction. It is often used to gain control or advantage bit by bit, avoiding immediate confrontation.

     

    PYQ:

    [2021] The US is facing an existential threat in the form of a China that is much more challenging than the erstwhile Soviet Union. Explain.

    Hurricane Milton

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Hurricane Milton

    Why in the News?

    Hurricane Milton made landfall near Siesta Key, Florida, USA which caused heavy rain, flooding and strong winds resulting in significant damage and loss of lives.

    Hurricane Milton: Origin and Causes

    • Hurricane Milton was a powerful storm that made landfall in Florida near Siesta Key, causing widespread damage.
    • It was a Category 5 hurricane with wind speeds of 285 km/h, making it one of the strongest hurricanes ever recorded in the Atlantic Ocean.
    • It originated in the Gulf of Mexico, an area connected to the Atlantic Ocean.

    Why it was an unusual storm?

    • Milton went from a Category 1 storm to a Category 5 storm in just 12 hours.
      • Usually, hurricanes intensify at a slower pace, but Milton’s wind speeds increased by 145 km/h in one day, which is very rare.
    • Sea-surface temperatures of 31°C were much higher than the 26°C needed for hurricane formation.
      • This excess heat allowed Milton to intensify quickly.
    • Most hurricanes follow a westward path, but Milton moved eastward and made landfall on the western coast of Florida.
      • According to scientists, very few hurricanes have taken this path before.
    • Wind shear is a change in wind speed and direction that can weaken hurricanes.
      • In Milton’s case, there was almost no wind shear, allowing the storm to grow stronger without interference.

    From UPSC perspective, the following things are important:

    Prelims level: Synthetic Medical Images, GANs

    Synthetic medical images are AI-generated images created without using traditional imaging devices like MRI, CT scans, or X-rays.

    Why in the News?

    As we consider how artificial intelligence (AI) is transforming various fields, one emerging area is the use of synthetic medical images in healthcare.

    What are Synthetic Medical Images?

    • Synthetic medical images are AI-generated images created without using traditional imaging devices like MRI, CT scans, or X-rays.
    • These images are constructed using mathematical models or AI techniques, such as generative adversarial networks (GANs), diffusion models, and autoencoders.

    Advantages offered

    • Intra- and Inter-Modality Translation: Generate images from the same or different types of scans, helping when certain scans are unavailable.
