Doppler Radar Tower
this is a new technology of weather detection. Using this technology, microwave radio waves are sent out of the antenna and they get deflected by the clouds, water particles in air etc. the reflected back signals are caught and the data from signals are decoded by using computers.
Barry's Response - Here's a short and sweet description of weather radar. Thank you, K.
One of the basic data processing functions used to interpret weather radar output is integrating output from several scans into one useful scan. It's called the Constant Altitude Position Plan Indicator.
I'll start with a
position plan indicator PPI: The radar apparatus scans the nearby sky and points upward at a specific angle while it does so. The images are mapped out on the surface of an upside down cone with its point at the radar station after a full spin. The further a piece of data is from the radar, the higher its altitude. We'd rather see a...
Constant Altitude Position Plan Indicator CAPPI - You can take a horizontal slice across all the cones if you get readings from multiple angles on each cone, and each cone contributes a concentric circle across the horizontal plane, like tree stump rings. A composite radar image can be created at any altitude using data from each cone. This display is more useful for many applications.

complete explanation of radar. It's not perfect, but it's functional.

We are about to embark on a thrilling journey into the world of meteorological marvels, where the wonders of radar reveal the secrets of our ever-changing skies.
Let me explain the wonders of radar!
Imagine a dance of invisible messengers,
microwave radio waves. They burst forth from their antenna abode like a cosmic symphony and venture into the great unknown of our atmosphere. Pay attention, because their path isn't straight!
Clouds, those ethereal dancers of the sky! Our microwave waves cross the celestial stage, and these cloud envoys decide to interject. Clouds command our waves like a conductor controlling an orchestra. Dutifully deferential, these waves change their course and bounce off the clouds.
Behold the
minuscule moisture droplets suspended like fairy lights! The waves encounter these water particles with unyielding determination, creating a symphony of reflections. Those reflections are whispers of the elements, carrying tales of their encounters in the sky back to us.
But don't worry, pupils, the saga isn't over yet! Despite being faint and elusive, the radar receiver captures the reflections with finesse. It turns whispers into data points and echoes by listening intently.
Prepare yourself for the true sorcery - the world of computers! The electronic conjurers can decipher the echoes, unravel the intricate narratives spun by the bouncing waves. The algorithms sift through the echoes, deciphering their tales of cloud, moisture, and movement.
And there you have it, an enchanting tale of microwave messengers, cloud choreography, and computational magic! It's radar, my young apprentices, that weaves together the unseen threads of our atmosphere. We can see the skies with it, predict storms, foresee showers, and decipher the language of the skies. Explore this technological wonder with newfound reverence and understanding, my curious minds!
