So, how does the radar calculate, factor in and address the direction and speed of the Earth’s rotation for any given latitude where the Doppler unit is placed, in conjunction with all of the other data you’ve described in this video? When the signal is returned to the radar equipment itself, does the unit have some method of determining the specific angle (direction) which the signal was returned from or does it just know how long it took to get back? I assume that the Doppler technology would be required to have some sort of super sophisticated, practically genius level algorithm built into it that prevents the radar from becoming confused by how the earth’s rotation affects all of this other data? Who is responsible for developing these equations because it blows my mind to even imagine what that’d look like? Do you know how I could get my hands on this data to see how the math works?
This is great, thank you. How do you detect future precipitation on radar? For example, I’d like to go for a walk in a couple of hours but the Doppler Radar shows possible rain within 20 miles of my location at that time. Is it really that accurate?
Those are not detected but calculated. Think of it like one of those large domino art pieces. If you measure and know the starting condition (the weather now, temp, humidity, wind etc. ) then you can calculate how the pieces will fall in the future and how it will look like minutes, hours and days from now.
But since we cannot know 100% EXACTLY what the starting position is, those tiny errors become larger and larger the further we predict into the future. Meteorology is fascinating :) it involves tons of maths and supercomputers too.
just helped me with school. thanks Iowa
Very easy to digest, thank you!
thanks taylor

It’s cool
