Visualising Wind from a GRIB Mesh Layer in QGIS and Create an Animated GIF

Today we're going to visualise storm Eunice. We'll use a GRIB mesh file with wind predictions from the HARMONIE-AROME Cy40-model. Then we style it with arrows and traces in QGIS, set up the Temporal Controller and a counter. Finally, we'll export the frames to create animations with GIMP.

Thank you so much. I always enjoyed your videos because they're absolutely beneficial.

Leuke toepassing van Qgis!
Heeft niets met geografie te maken, maar het kan.
Onbeperkte mogelijkheden.

Using QGIS 3.22 and following your tutorial I am able to animate wind contours but in Layer Styling the Show Vectors option is disabled. Am I missing a required plugin? Any advice appreciated. Thanks.

Thank you very much for your video, it's been very helpful to me. However, I have a question about traces that I hope you can answer: I understand that the arrow icon can differentiate wind direction and speed through its orientation and length. But in traces mode, I can see that the color of the lines represents wind speed. One line may indicate a continuous track of the wind, but these lines vary in length. I don't understand what these lengths represent, so I'd like to ask for an explanation regarding this aspect. Looking forward to your response.

Can you create wind swath also (eg. hourly model output using three grib files)? Thanks

Hi Hans, have you also done any GIS work using solely R? Or would you prefer using Python over using R?

[dantasfelipe]

Excellent tutorial, as always. Do you know any such datasets for Brazil?

[DionisioTejedaWx]

How do you create contours to mesh data?

[mohamedsufi]

Amazing. Thank you.
Is GIMP a free software?

Hi Hans, Such a useful video. Is there any possibility to show also the wind speed of the respective time on the map?

Sir, Can I download this data for India??
