Cyclones and gales.- Storm conditions decreased materially over the
North Pacific from March to April. No deep cyclones entered the
western part of the ocean from Asia until the end of the month, when a
storm with pressure readings below 29 inches crossed northern Japan on
the 30th, accompanied by a strong gale on the south coast of Hokushu.

Several cyclones of moderate intensity in immediate Japanese waters
developed considerably in strength over the ocean in their passage
toward Aleutian waters. This was particularly true of the Hokushu Low
of April 5, which caused fresh to strong gales to the eastward on the
6th, and a gale of force 11 near 48' N. 163' E., on the 7th.

Another depression, which left Japan on the 11th, caused fresh to
strong gales as far to the eastward as 165' E. on the 12th to 14th.

If you want to play with my ideas about the lunar phases part of this,
remember to subtract 4 hours from the times of those phases where a
strong cyclone was active near Japan and maybe that whole region of
the Pacific.

Going through the Tropical cyclone records I noticed that the MetO has
this to say about Ketrina:

Katrina 12L NAT 23 August 30 August 150 -

That is active in the North Atlantic Basin between 23rd to 30th
August. No 10-minute MSW

That is there is no given quantity for the maxcimum sustained wind
speed (in knots) averaged over 10 minutes.

Anyone know why?
