Radar map’s glitch

@AeroZ
The forum is the only way to contact Windy team members. They are here during office hours CEST time. So next time on Monday.

Suty

@AeroZ Another way, how to contact us, is by email at support[@]windy.com. I will discuss this radar interferences with our colleagues and let you know about the potential result.

Suty

@AeroZ According to the topic, these interferences are standard for radar images. The good thing is that our colleagues are working on certain improvements, so it is possible that it will be filtered in the future.

AeroZ

@Ondřej-Šutera thanks. Hopefully a solution will be found.

AeroZ

Any update?

Suty

@AeroZ I discussed it with colleagues and it hopefully will be in the version 41, which is next in our plans.

AeroZ

@Suty Looks like it’s still not fixed.

As explained here above, this is interferences by WiFi sources.
You said that some apps don’t show these interferences. This is because they don’t show REAL WEATHER RADAR data. They show a radar-like picture that is computed from some satellite data.
Is it possible to check that an app show really weather radar data ?
These radar-like pictures show rain over the oceans where there are obviously NO RADAR offshore.

Accuweather (not real radar)

Rain viewer (real weather radar + interferences)

Meteoblue (not real radar)

Meteologix (real weather radar + interferences)

Windy cannot fix it. This glitch should by fixed by the Latvian Weather Center or at better by the Agency controlling the radio frequencies in Latvia

@idefix37 wifi over that big of an area?

@AeroZ
It is not the WiFi sources themself which produce these long spikes, this occurs when the frequency of these sources is the same as radar frequency (using the same channel). So the radar sees an echo.
Did you check the link in my previous post?

By the way are you able to show us the native radar pictures provided by the Latvian Meteorology Center ?

AeroZ

@idefix37 i’d have to try and find it. I don’t live in Latvia. It just looks like Latvian radar is closer to my location than the Estonian one (up north I think).

Again, since you seem not convinced that WiFi interferences with weather radar can cover such big area, please check this link
interferences by WiFi sources.

@idefix37 I’m not saying that I’m not convinced. I’m just surprised that it’s wifi.
