Doc Weather has been scratching his head over this one. The intensity and far reaching effects of the recent spate of storms into the West Coast was puzzling. The eclipse grid showed mostly high pressure values for the last week of December. What could be the source of such violent winds and flooding rains? Checking back in the records the charts do indeed show a predominance of high-pressure values on both eclipse points over the mid Pacific. There was no mistake there. Then an important relationship came into focus. The high-pressure was being generated by a tandem relationship between Saturn, over Indonesia and Jupiter over the mid Pacific. At first, planets that are so far removed from each other don't appear to be working in tandem but a closer examination of the relationship reveals that on the 18th of December Jupiter moved to a 90° angle to Saturn. On that day a strong surge in the jet stream off of the Asia pushed jet stream winds across the western Pacific. Each day since this streaming has moved farther east across the Pacific. These winds that started on the day the Jupiter squared Saturn, started in Indonesia but were ultimately directed at the western United States. The pattern for this is not unprecedented. Doc Weather found another similar pattern between Jupiter and Uranus in 1999. The character of the storms in Europe that year was similar to the recent storms on the West Coast.
The chart in figure 1 shows the position of the eclipse grid in December 1999. Uranus is over the US and Jupiter is over W Africa. They are exactly 90° apart (red line) during a tremendous rush of jet stream air across the Atlantic that slammed into Europe as the winter equivalent of a hurricane bringing high winds and flooding rains. It can be seen from the chart that an anomalous high pressure area runs from Florida to the Azores. The jet stream (red arrow) is tracking the northern edge of this high as it makes an approach to the disturbance diamond that is just off of the west coast of Europe. The high is carried along the tops of the 22° and 45° jet curves as they are placed across the ocean. The disturbance diamond is over the west coast of Europe. The jet stream moves across the ocean and meets the high against the coast and turns north into Europe. This pattern is not so unusual in itself. What is unusual is the extreme length of the trans Atlantic jet. It can be seen that the jet is following the 90° aspect line between Jupiter and Uranus. It is as if the jet stream got supercharged by the tandem relationship between the two planets. At that time Doc Weather saw the 90° aspect but didn't know how to read it until case studies were done after the event.
This image shows the current eclipse grid and the placement of an anomalous high pressure area across the southwestern parts of the Pacific. Saturn, over the western Pacific and Jupiter, over the mid Pacific are at an angle of 90°(red line). The jet stream coming off of Indonesia is racing across the Pacific following this line and ultimately sending a plume of moisture into the West Coast. Similar to the last chart, the jet stream is following along the tops of the 22° and 45° jet curves as they are aspected to high pressure from Jupiter near the eclipse points. On the continent, a high pressure area linked to the disturbance diamond over the southwest US has pushed up a ridge into Western Canada that is steering the polar jet to the south over the eastern Pacific. The combination of the two high pressure areas has created a kind of wind tunnel across the Pacific that is ferrying moisture towards the coast. The key element here is the Saturn and Jupiter tandem at 90° that is aiding a strong jet off of Asia to stream across the open ocean. The similarity between the chart from 1999 and the chart for 2005 is striking.
This time Doc Weather knew what to look for but unfortunately he didn't look. It should be noted that the position of the eclipse grid with the 22° and 45° jet curves at a low latitude across the ocean in both charts is an aid in the establishment of such an arrow like jet stream. Also, in both charts the streaming jet is approaching the coast of a continent where the disturbance diamond is generating some blocking energies. This is the real force in this pattern. Elements that would work against such a pattern would be if the 90° angle had continental barriers and mountains in its track then it is doubtful that such a linkage would produce such a strong and continuous jet stream. Also the winter placement of the storm jet to the south across the Pacific is a great aid to establishing this pattern. In summer the jet stream moves to a far northern position.
The next time that Jupiter and Saturn square off against each other is in late June 2006. In the summer the jet stream is in its northerly positions so it is unlikely that the mid latitude jet will be influenced by this event. However, Jupiter will be going retrograde at that time. In that locale the winter jet splits with part of it moving north to settle in the Sea of Ohotsk and another part sinking south into the easterlies to steer typhoons into Asia. Given the timing and placement of the future square between Saturn and Jupiter, a good bet would be that southeast Asia will be the site of some remarkable winds and storms in the latter half of June and the first half of July.
