An example of the potential impact of recent ERS-2 user wind product (UWI) data is illustrated in this image. It shows the analysis of 4 May 2003, 12 UTC north-west of Scotland for mean-sea-level pressure
(blue contours) and streamlines (beige) of the 10 m surface winds. With the new tool ESACA ERS-2 scatterometer winds (white barbs), observed around 11:24 UTC, are displayed as well. The detailed structure of the warm front is well presented by both the analysis and the scatterometer winds.
However, the scatterometer winds suggest a small shift southwards of this front, and besides, a shift towards the east of the low-pressure centre.
