The radar is capable of forecasting rainfall in a radius of about 450kms and strong winds in a radius of about 200kms
KARACHI: The Pakistan Meteorological Department (PMD) on Friday activated a modern doppler weather radar in Karachi after a period of 30 years.
The doppler radar is capable of forecasting rainfall in a radius of about 450kms and strong winds in a radius of about 200kms.
The new radar, which was built at a cost of around Rs1.58 billion, is also capable of providing timely reports of cyclones and other tropical storms in the Arabian Sea and Bay of Bengal regions.
The PMD department had also provided a link to radar imagery on its website. The weather device would be able to detect conditions much faster as compared it its analogue predecessor which was installed in 1991.
The new device was supposed to be activated before the monsoon rains of 2020, however, due to the pandemic, the operation was delayed.
According to met department Director Sardar Sarfraz, the new radar has twice the wavelength as compared to the analogue equipment, which had about a wavelength of 10cm.
“Unusual activities including thunderstorms, cloud masks and others can be observed simultaneously from the east, west, north and south with the new doppler radar,” he said.
He added that the state-of-the-art device would also be able to predict rainfall in advance, in both millimetres and centimetres, two to six hours before its occurence.
“This will facilitate town planning and forecasting for rainwater discharge. It would also detect passing weather systems near the city,” he added.
Sarfaraz further stated that the radar would also be helpful for the aviation industry as it would be able to gauge strong winds.
“Flights and ships will be protected from hazards. The system of international shipping and shipping traffic forecasting will be improved. A quick warning will be possible in case of storms, rains, hot weather and other weather disasters,” he added.
He added that fishermen will also be warned of inclement weather conditions and storms.
“People living in the coastal areas of Balochistan and Sindh will be provided with accurate forecasting and warning,” he said, adding that the new radar would reduce the loss of life and property due to natural disasters in Pakistan.
Before cloud storage, USB drives, and smartphones, there was the 1.44 MB Floppy Disk—a symbol of the early digital age that transformed how the world stored and shared information. For millions of people, the floppy disk was their first experience with digital storage, carrying school assignments, office documents, software programs, games, and precious memories.
Today, this iconic piece of technology has become a collectible artifact, representing an era that laid the foundation for the modern digital world.
The Legacy of the 1.44 MB Floppy Disk
Introduced as one of the most widely used storage mediums of its time, the 3.5-inch floppy disk became a global standard throughout the 1980s and 1990s. Although its storage capacity of 1.44 MB may seem tiny by today’s standards, it was once considered revolutionary.
Students carried their projects on floppy disks. Businesses stored important files and records. Computer enthusiasts exchanged software and games using these small plastic squares that became an essential part of everyday life.
A Nostalgic Tribute for the Digital Generation
The 1.44 MB Floppy Disk Heritage Frame transforms this historic technology into a premium display piece. Carefully mounted within an elegant 8×12-inch frame, it serves as a reminder of a simpler and pioneering era of computing.
Whether displayed in an office, study room, technology lab, or home, the framed floppy disk sparks conversations about innovation, creativity, and the remarkable journey of digital technology.

The era which we are praising
today is the product of the intellects of many millennium. Those are the gems
of intellect that worked out at that time when there were no scientific
resources. Those people have observed their surroundings and have produced
resources for humanity. The intellectual Muslims have contributed to every
field and their contributions are most valuable. Today all the advancements are
based on the discoveries and inventions of ancient scientists both Muslims and
Non-Muslims. Modern scientists are working and producing technological items that
are also based on the ideas of ancient ones.
Al-Hassan Ibn al-Haytham of Basra
is known to be the pioneer of Optics. He was the product of the Golden Age of
Muslim Civilisation that was a creative time period and brought out many
far-reaching advancements in the field of science, mathematics, and medicine.
He was the greatest Muslim physicist and one of the greatest students of optics
of all time. He was inspired by the works of other great philosophers and
scientists who were before him such as Aristotle, Euclid, Al-Kindi, Banu Musa,
Ibrahim Ibn Sinan, and Ibn Sahl. Ibna al-Haytham based his theories on the work
of Greek physician Galen. He is the one who introduced the methods of
verification, testing, and experimentation for the exploration of truth. He has
written books as well and in one of his books he says: “If learning the truth is the scientist’s goal . . . then he must make
himself the enemy of all that he reads.”
He was the person who has given
the concept of how vision works. And he has written a book about the “Book of
Optics” in which he has illustrated the eyes and optic nerves. He has drawn
images of eyes which have been used by the modern scientist to understand and
to produce lenses and other optics items. Al-Haytham used a dark chamber to
explore the nature of light and vision. Through this experiment, he observed
that light entering through a small hole would travel straight and would
project an image onto the opposite wall. From this concept, modern cameras have
been designed.
Today, if we can have different
lenses and glasses to replace or improve our vision artificially and can
capture our every moment, is all because of Al-Haytham. The world is grateful
for all his contributions.
