Mercury is shifting gears over the western Pacific. - 12.02.06

Since the shift to direct motion by Mercury the complexion of the current El Nino has changed.



This image is a section of a 500mb difax upper air map for December 2, 2007. There are several features of interest in this chart that point to changing conditions in the eastern Pacific. The North American continent is outlined in blue for ease of identification. The blue circle just below the Mars position is the Hawaii chain. The yellow area in the north is a new, high latitude blocking high pressure area over Alaska. The long pink arrow is the jet stream that has suddenly started to vigorously stream from Asia to past the dateline (180° in the chart).

In previous articles we have been tracking the squeeze pattern instigated by Mercury as it opposed the group of planets near Hawaii earlier in the fall. At that time Sea Surface Temperatures (SSTs) rose in the area of the dateline and diminished to the eastern tropical Pacific. For seven days now Mercury has come out of retrograde motion at the dateline and joined the others in direct motion across the eastern Pacific. If we could see a movie sequence of the charts for that week we would see that the jet stream off of Asia began to stream out into the western Pacific off of the continent at mid latitudes on November 26. Which was four days after Mercury made the shift. The strength of this trans Pacific jet is a signature of El Nino. In that pattern the jet stream off of Asia makes an unbroken surge past Hawaii before splitting into two streams, one far to the north and one south along the West Coast.

The prerequisite for this surge is that there needs to be a high pressure area stuck over Alaska to keep the pressure there like a lid on the north Pacific preventing the jet stream from looping farther out from the coast. In the last few days a high that was being carried along from the Kamchatka peninsula in eastern Siberia got caught in the lee of the chain of 14,000 ft peaks along the spine of the peninsula (the peninsula is just at the bottom of the 493 low that is to the west of the Alaskan block. It juts out into the ocean like a finger. )

These events are the opening round of changes for the current El Nino and with Venus, Mercury, and Mars scheduled to pass the West Coast between now and the end of January, the events that are now unfolding in the eastern Pacific bear close scrutiny.
