The issue you're experiencing with particle positioning in the OLWindLayer compared to platforms like Ventusky and Windy.com could be due to several factors related to data projection, rendering settings, or differences in how the wind data is processed and visualized.

1. Projection and Alignment: Ensure that the wind data is correctly projected and aligned with the map's coordinate system. The OLWindLayer uses project and unproject methods to handle transformations between geographic and pixel coordinates, ensuring alignment with the map's view ^[1][2].

2. Wind Data Format: Verify that the wind data JSON file is in the correct format expected by the OLWindLayer. The structure and format of the wind data can affect how particles are positioned and rendered.

3. Rendering Options: The OLWindLayer provides several options that can influence particle behavior, such as velocityScale, colorScale, and paths. Adjusting these settings might help align the visualization more closely with other platforms ^[3][4].

4. Map Zoom and Particle Density: The OLWindLayer handles map zoom events by adjusting particle positions to maintain consistent density. This is done using the viewportZoomChangeFactor uniform, which might affect how particles are displayed during zoom interactions ^[5].

5. Comparison with Other Platforms: Differences in particle positioning might also arise from how different platforms process and visualize wind data. Each platform may use unique algorithms or data sources, leading to variations in the visual output.

To address the discrepancies, you might need to experiment with the OLWindLayer settings and ensure that the wind data is correctly formatted and projected. Additionally, reviewing the wind data JSON file and comparing it with the expected format could help identify any potential issues.
