我打开windy.com的加利福尼亚地区，我发现加利福尼亚电流以相反的方式显示-从南到北。它是受最近的气旋影响还是我误解了windy.com?
看到你关于Windy上电流的一系列问题，我对Windy展示的是什么产品有点兴趣。无论是表面洋流，最大值还是平均值。我找不到任何相关信息。当然，风会改变地表水的流动，所以我希望如果《Windy》表现出它特别容易发生变化。即使在较深的地方，风也能驱动相当多的电流。由于风的方向远不是静态的，所以这种电流也不可能是静态的。强气旋在美国太平洋沿岸并不罕见，特别是在一年中的这个时候。
但是快速搜索一下西海岸的洋流，就会发现变化更加明确和典型:

太平洋沿岸逆流，沿美国西海岸北行，自墨西哥下加利福尼亚州至俄勒冈州北部，止于北纬48°N
… it flows north rather than south and hugs the coastline. The current is active year-round at 650 feet (200 meters) below sea level, but surfaces during the winter months, generally from mid-November through mid-February. In these months, northerly winds weaken and are replaced to some extent by southwesterly winds.
(note also that in your image, the flow still mainly has a small north-to-south component hundreds of miles offshore, which would tend to match the diagram)
Finally, tying it all together, it looks like the paper Buoyancy-Driven Coastal Currents off Oregon during Fall and Winter (Mazzini et al, 2014) suggests that the winter south-to-north near-shore current may in part be caused by the increase in amount/scope of river discharges that are typically greater in the winter there (due to the increased precipitation). Such that, while the water being discharged is colder than the ocean it flows into, its density difference (being freshwater) can cause it to flow north.
If that's true, an exceptionally rainy winter along the US Pacific Coast should indeed mean a stronger northward winter current.
But it looks like some degree of northward current right near the coast is quite common in the winter, so this appears to be normal.
