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.

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.

Whilst a Low of 999 mb is still a low, it is not much of one. The
isobars of the one around the UK at the moment:

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:

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.

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.

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.

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:
