This spell runs from April 28th to May 5th. I expect an earthquake in
the region of 7.3 to occur early in it. However there was a series of tornadoes running at the end of the last spell so maybe it will not arrive. 14:12. That's nearly quarter past two. A spell that generates tornadoes. I don't know how much effect the storm in the Indian Ocean is having and will have on things. Frankly this one is a steep learning curve for me. |

The Low over Britain isn't producing much in the way of rain. Quite nice really, with some light showers. All very odd. |

The isobars of the one around the UK at the moment: http://www.westwind.ch/?link=ukmb,ht...racknell+13 2 extend half way over the North Atlantic. Were the anticyclones a little less high (1032mb off Canada and 1017mb over Scandinavia) I'd guess that activity at several volcanoes is increased. Actually the extent of the Scandinavian one is just about right. It will be a week before we can find out on the Smithsonian site. One can check up on the individual sites of likely suspects. There is a list on he http://www.volcano.si.edu/reports/usgs/index.cfm A high of 1017 mb is pretty flaccid and so is a low of 999 mb. They are pressures more commonly found at lower latitudes. And I imagine might be likely in regions that suffer tornadoes. So a relationship with natural disasters incorporates a pressure range of 995 to 1020? I wonder what else they have in common besides the same root cause. It would be nice if the NEIC site gave surface level pressures along with mean power values. Meanwhile I'd guess by the asymmetry that the volcanic event, if any, is Hawaii again. If I had to guess. But we all know what they are worth. |

Nargis 115 knots and right on landfall:
http://205.85.40.22/jtwc/warnings/io0108.gif The region is usually devastated by any storms in the region coming ashore, as deforestation all the way up to the tree line in the Himalayas and bad land management right down to the shoreline has coupled to cause now traditional flood disasters all through their rainy season. A major increase in the factor is the caste system if it exists in Muslim countries, where the needs of replenishment do not fit into the overall scheme of supply and demand. http://www.country-studies.com/bangl...ification.html It didn't happen under the Raj, Asian or British. Not to the same extend at least. The last I heard is that the prawn industry worldwide is even ruining fish stocks there. Corruption, ignorance and the inability to combine so as to deal with the obvious rules KO. |

There is almost no definite cyclone or anticyclone in the North
Atlantic and the only decent "dartboard" in the North Pacific is a low with a core surface level pressure of about 990 mb. https://www.fnmoc.navy.mil/efs/dynam...pac_gale_0.gif https://www.fnmoc.navy.mil/efs/dynam...atl_gale_0.gif I think that means a negative anomaly in both oceans. The Arctic has a well defined High though, in the Gulf of Alaska. There is a relative difference in core pressures for the same wind speeds: Dn Kn NA NWP 2.0 30 1009 1000 2.5 35 1005 997 3.0 45 1000 991 3.5 55 994 984 4.0 65 987 976 4.5 77 979 966 5.0 90 970 954 5.5 102 960 941 6.0 115 948 927 Dvorak Number - Knots - Pressure in Millibars - Altantic - Pacific. http://en.wikipedia.org/wiki/Dvorak_technique I suppose that is the last anomaly I aught to be interested in but it IS interesting. |

I missed a rather special event in the Arctic. An high of 1056 just NW of Greenland. That can't be far off a record for seal level pressures can it? Nagris has hit Rangoon in Further India. Two major rivers drain Burma both port near where that storm broached: http://www.mizzima.com/news/breaking...s-hits-rangoon |

Now a gale of 40 knots and the weather in the UK has reverted accordingly. Soon we will see those tell tale earthquakes that match almost to a tee their location. I wonder where. The begged question to answer next is: Can those two be predicted? I think I need to learn how to use a data base and will probably have the time to do so before that particular penny drops. The seismicity in the Andreanof Islands kicked off again at that storm's peak too. I want to believe that the low deepening in the North Atlantic ATM is the key. It breaks up at 1004 on Wednesday the 7th: http://www.westwind.ch/?link=ukmb,ht...racknell+13 2 But the spell ends or changes perhaps on the 5th so it's anyone's guess what happens then. I'm not saying anything. It goes on for a full 9 days on this site: https://www.fnmoc.navy.mil/efs/cgi-b...ntic%20Bas in) Well, anyway; that's the best I can do. |

Worranijit: 5.0 M. 2008/05/03 02:36. 42.8 S. 72.3 W. Los Lagos, Chile. 5.3 M. 2008/05/02 05:51. 42.7 S. 72.3 W. Los Lagos, Chile. Fancy missing them. Would you believe I was looking for a pause rather than the pair. Besides, I was expecting a couple of 6's. Anyway the storm has gone. |

New things learned:
When a flaccid set up pertains in the North Atlantic and the Lows don't behave the way that they are supposed to, expect: "The population of Chaiten in Chile has been evacuated after a volcano began to erupt, covering the town in ash. The volcano spewed ash and caused tremors in the region on Friday, forcing water supplies to be cut off, the authorities said. By Sunday the town, about 1,300km from Santiago, the capital, was covered in ash. It is the volcano's first eruption in at least 2,000 years, according to Sernageomin, a government mining and geology agency, and caused the Patagonian town of nearly 4,500 people to be emptied. Many evacuees travelled by boat to Chiloe Island to the north and Puerto Montt on the mainland." http://english.aljazeera.net/NR/exer...65B04D27BA.htm |

An interesting Low in the North Atlantic this. It wouldn't surprise me if it continued all through the next spell too. This morning a Cat 4 tropical storm appeared over Japan. No warnings from any agency I saw. Anyway the sun's coming out again after some drizzle yesterday. That Low after being stationary over the other side of the Mid Atlantic Ridge for a week moved quickly at the end of the last spell to Britain and with this spell has returned to the west it is now 35 degrees west and apparently filling. Which could mean another eruption and then it will probably move quickly west again. Wednesday looks favourite: http://www.westwind.ch/?link=ukmb,ht...racknell+13 2 |
