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 - A short and sweet description of weather radar. Thanks, K.

One of the basic data processing system functions used for interpreting weather radar output is a system that integrates output from several scans into one useful scan. We call this the Constant Altitude Position Plan Indicator.

I'll start with a position plan indicator PPI: The radar apparatus spins around scanning the nearby sky and while doing so it points upward at a specific angle. After a complete spin the images are mapped out on the surface of a cone...an upside down cone with its point at the radar station. That means the further a single piece of data is from the radar, the higher its altitude above the ground. That might be useful but normally we'd rather see a...

Constant Altitude Position Plan Indicator CAPPI - If readings from several angles are given, each on its own cone, all the cones can be placed with their vertices together and a horizontal slice taken across all of them, with each contributing a concentric ring across the horizontal plane like the rings in a tree stump. The software takes a bit of data from each cone to create a composite radar image at any desired altitude. We find this display much more useful.

Here is a more complete explanation of radar. This is not without its problems, but it IS functional.

This is a very common to hear about the weather condition today is hot or rain going to happen, but no one has information how they forecast about the weather more technology used for making this kind of forecast.

This system definitely deserves
by: Darry

This system definitely deserves some attention. If we could install systems like that all over our country we could have so much more control in terms of weather forecasts. It shouldn't be that difficult to use, after all any technology can be explain if you're willing to learn.

Everyone familiar with grad school admissions may explain which engaging in graduate student school is just not because basic because using a cutoff GPA or perhaps GRE report.

What benefits?
by: asvd

It looks cool to see the picture. but I like know what benefits we can get from this new technology when comparing traditional one?. Also how much cost it takes generate microwave signals? But India is moving up with these new technologies

This article was very interesting. I did not know that there was new technologial weather detection. Another radar is a good thing I think
