What got updated in the 7.21 version this time?
-
@admin1031 Yes, this Meteoblue MLM is in this latest version of Windy.
-
@Suty Where is the 5880 line at the 500 hPa level? It seems like I can't find the contour line location, and the visualization of contour lines at each level doesn't seem very clear.
-
@admin1031
Geopotential heights isolines (isohypses) are generally provided in dam units (decameter). In Windy there are displayed in meters. 588,5dam and is not far from 588dam.
-
@idefix37 Yes, although it is displayed, these contour lines don't seem very stable. The 5880 line is a subtropical high-pressure system in meteorology. Usually, the edge of this high-pressure system is where heavy rain occurs, especially in China, as it determines the position of the East Asian rain belt. Beyond the 5880 line is the center of the subtropical high, which brings hot weather. During summer, when typhoons or hurricanes form, the 5880 line plays an important guiding role. So, I think this contour line is very important at the 500hPa level.

@admin1031
Because Windy does not focus on this particular isoline. Same for 528dam which is said to show a risk of snow.
Or for the 1013hPa isobar.
The way how Windy plots these isolines does not include specific values to be displayed or at a specific interval. -
@idefix37 But sometimes when I look at the 500hPa level, especially in winter, analyzing the positions of troughs and ridges isn't very convenient. I can only judge them through the winds at the 500hPa level, and the Windy 500hPa contour lines aren't fixed, which makes weather pattern analysis difficult. So I have to rely on other numerical websites. I think meteoblue does a good job with the 500hPa level; meteoblue combines the 500hPa height field with surface pressure.

@admin1031
Yes I like this useful map and requested it several times to Windy. Without success. -
@idefix37 But I don't know why it didn't work. I had previously suggested that the Windy program could add temperature changes at the 2m and 850hPa levels, which is very useful in winter. I didn't receive any response, but other users have also made similar suggestions, and it seems the feedback is that there is no specific plan.
-
@Suty Yes, yes, yes, please reinstate the cloud, rain/snow in the airgram, it's essential for mountain weather. You could also include freezing level and snow levels to make it even better!
-
@idefix37 It is said that the product with the perceived temperature came out on July 21st, but I can't seem to find it in the product list on the web version.
-
@admin1031
This temperature is displayed in Basic table.
Personally, I don't see the point of showing "feels-like" temperature maps of merely subjective temperature.
-
@idefix37 The perceived temperature needs to be checked for a specific location, it doesn't seem as intuitive as showing it on a map.
-
@idefix37 On meteoblue, you can select the feels-like temperature and display it on a map, then click on a specific location to see the feels-like temperature value. This way of displaying is more intuitive than just choosing a single location.
-
@admin1031 Right now, we offer this Feels like temp. for the first time so we decided to display this dataset in our forecast detail. If there will be any more significant feedback about this, we can implement the map with this dataset as well, but it is not planned for now.
-
@Suty I have another question. Currently, China has a global weather model called CMA-GFS with a data resolution of 12.5 km. Will this model be added to the Windy program?
-
@admin1031 Hello, as far as I am aware, this model is not planned now. We have general trouble with access in China, we have many reports about disfunction of our whole app there, since the local network is trying a lot to block our app. So from this perspective, we are not planning any local model now.
-
@Suty As a user, I don't seem to have encountered this situation. Nowadays, many people in China use Windy, and it works fine. Plus, domestic network technology in China has already been upgraded to 5G, so the internet speed is pretty fast now.
-
@Suty As a Chinese user, I can normally access the mobile app and desktop website, but the Windy web version on my phone is very slow and basically won't open. I wonder if using a VPN would make it a bit faster.
-
@admin1031 Can you please test this VPN usage for us?
-
@admin1031 Hi, yes, we try to let our Chinese users to access Windy.com even though there are some restrictions on Chinese government's side. That means that access from China is unfortunately much slower than we'd like it to be. VPNs should make it faster, as long as their exit nodes are (obviously) outside of the PRC.
