![]() The relationship with large magnitude earthquakes seems to be a compression of millibars at sea level between the east coast of greenland and a point just to the north of Lapland, somehwere between Svarlbad and Western Norway. IIRC someone posted a link to sea temperatures some time in the middle of December, this set up was followed by a high pressure system over the NW Atlantic. Immediately after the large quake the system returns to a flaccid "negative anomaly". Anyone know what was happening aloft at the same time. I have the Bodendruck charts from way back from WetterZentrale and have no idea what to do with them. If I know what sort of anomalies to look for I might. For our cousins across the way the weather sites to search for are all in Germany: http://www.google.co.uk/search?hl=en...ndruck&spell=1 (Don't mention the war, they might ask us who won.) |

What the hell does "compression of millibars " mean? At a guess, a close spacing of isobar lines on a barometric pressure map. This results in a pressure gradient from the area of high pressure to low pressure. The closer the lines, the higher the wind speed. What that has to do with earthquakes is only in his mind.

I'm never quite sure if it's the weather that causes the earthquakes or the earthquakes that cause the weather. Did he predict Haiti?

Thus far, at least as far as I can tell, no one in this newsgroup has ever made a proper prediction of any significant earthquake, save for post facto. -- ************* DAVE HATUNEN ) ************* * Tucson Arizona, out where the cacti grow * * My typos & mispellings are intentional copyright traps * |

What the hell does "compression of millibars " mean? I was looking at the sea level pressures, the sort you might see on the TV bulletins or in the "better" newspapers. When the pressures are high for both cyclonic and anticyclonic vortices, the system can go critical somehow. And this occurs with a large magnitude earthquake. The same is true with flaccid set-ups. They produce tornadoes. With an High over Greenland and another to the south east and a series of Low pressure vortices pushing through between, the critical point is 970 millibars or so. The day of the tornado it is back up to 980 or so. There is a 10 mb difference in the charts from the day before. I have just been looking at about three or four spells where Derechos were reported. The set up is reversed. It seems that for derechos, the dominant set up is a Low to the north west and another to the south east. And an High pushing through. But to answer your question. I was looking at the dates of severe earthquakes and turned up the North Atlantic Chart. When I went back one day, I saw the isobars were very close together for an High and a Low. This pattern was produced over and over again. I know there is a distinct frequency for angular distances between Lows and earthquakes (they occur 80 degrees apart, as I have stated frequently so you aught to be familiar) seeing the proximity of the Highs -which also have this 80 degree relationship though I have not bothered to look closely at those. It crossed my mind that it might be easy to locate probable epicentres by working out where these two coincidents coincide. I bet it is 90 degrees. That would make a lot more sense than 80. |

Bear Island and Shannon Island off central East Greenland.

Paul someone or other. I forget. Immediately after the large quake the system returns to a flaccid "negative anomaly". |
