Well I explained it a few days ago. But basically the warm pacific air causes the heights to be well above normal. So as a result you get those big reds and whites that look like Massive + anomalies. But, you can tell it may be sort of masking what may be occurring, because there is no anticyclonic curvature. The key to seeing this, are the more zonal looking height lines as shown below. Ryan also said this too. Imo, there is ridging, however I’m not sold on it looking as strong as it shows based on those height anomalies.
This actually is common in El Niño’s. So we’ll see as we get closer. I know it may be a smoother out mean beyond 10 days, but I am keeping an eye on it. Just something to watch.
