Meteorological Cyclone Data




THE NEW ZEALAND GAZETTE. 345

  1. It will be more convenient first to trace the
    course of the cyclone in the N. W. corner of the Bay,
    where we have land observations* and those of the
    floating light-ships to guide us, and afterwards to
    follow it back as far as possible to its origin.

recorded barometer is at 4 a.m., when the wind had
veered to S.E. The centre, which had been approach-
ing Saugor from about south up to 3 a.m., must have
curved round between 3 a.m. and 5 a.m., from which
hour it moved away towards west, bearing about
S.W. from Saugor.

  1. On the afternoon of the 29th, Saturday, the
    wind moderated, and a lull was experienced north of
    the area of low pressure in the Bay. This was
    probably due to the breaking up of a vortex, which
    the log of the "Coldstream" seems to show was
    formed, or partially formed, on the 28th and the
    morning of the 29th. This lull, however, was of
    short duration. At the Mutlah floating light station,
    the wind, which had moderated at noon, at 4 p.m.
    had increased to a strong gale; with very unsettled
    appearances. At midnight it was blowing a hard
    gale, with constant heavy rain. On the morning of
    the 30th, Sunday, a heavy gale was blowing from the
    eastward, with continuous torrents of rain. At noon
    the barometer was falling rapidly, the wind blowing
    with the force of a hurricane from the east. The
    barometer was lowest at 6.30 p.m., and between this
    and 8 p.m. the centre of the storm must have been
    nearest to the Mutlah light-ship, the "Comet;" but
    if the directions of the wind are correctly given, the
    "Comet" was outside the radius of the cyclone.

  2. The following notes on the cyclone were
    forwarded to me by Mr. Richards, Civil Surgeon at
    Balasore :-

" 7.30 " 28.62 N.W. Increasing.

" 9.30 " 28.41 E.N.E. gusts.
" 11.30 " 28.50 E. Still blowing very

Rainfall 6 inches.

  1. The observations of the floating light-vessel
    "Star" at the Ridge Station, latitude 20° 49′ 45″ Ν.,
    longitude 87° 41′ 19″ E.; the floating light-vessel
    "Meteor" at the lower Gasper Station, latitude
    21° 26′ 53″ N., longitude 88° 6' E.; the steam-ship
    "Madras" at anchor in Saugor Roads, and those at
    Saugor Island and Balasore, afford sufficient data
    for determining approximately the track of the
    cyclone, assuming that the latitudes and longitudes
    of the floating light-vessels (which were not given
    with the extracts of their logs which I received, but
    which I have since obtained from Captain Falle,) are
    correct.

  2. In applying these observations to determine
    the track of the centre, it should be observed that the
    directions of the wind are probably only very approxi-
    mate, and that before Balasore came within the
    cyclone's radius the prevailing wind must have been
    north-westerly. It is probable that the first recorded
    cyclone wind was from N.E. at 8.30. At all events
    it is tolerably certain, from the directions of the wind
    at Saugor Island and at the "Meteor," that the
    centre of the storm could not at any time have been
    north of a line drawn between Balasore and Saugor.
    Storms generated in the north of the Bay so late in
    the season seldom possess sufficient energy to travel
    inland, and generally burst up when they come in
    contact with the land. The present storm was not
    one of great violence, and was unusually small in
    dimensions, its radius probably never exceeding 40
    or 50 miles. It advanced in a northerly direction
    very slowly from midnight, retarded by friction with
    the land. Turning round to the westward, along a
    path of less resistance, with probably a much smaller
    radius, it increased in extent and velocity of pro-
    pagation as it moved over a freer course towards
    Balasore.

  3. From noon to midnight on the 30th the
    "Star" experienced terrific squalls, the wind being
    steady from N.N.E. up to 8 p.m., when it veered to
    N. The centre of the storm had been thus approach-
    ing the "Star" from S.E., and at 8 p.m. its bearing
    was about E.S.E. Two hours later the wind at
    the "Meteor," which had been steady at N.E.,
    veered to E.N.E., the centre bearing consequently
    about S. At 10 p.m. the centre of the storm was
    about in latitude 20° 40′ N., longitude 87° 55′ E. At
    11 p.m. the wind at the "Star" had veered to
    N.N.W., while the centre continued to bear about
    south from the "Meteor." The position of the
    centre at 11 p.m. was about in latitude 20° 50′ N.,
    longitude. 87° 53′ E. At 11.45 p.m. the "Star"
    parted and drifted from the station. At midnight
    she had the wind W., the centre bearing about
    N.N.E. At the same time the "Meteor" had the
    wind W., the centre bearing about S.S.W. Position
    of centre at midnight about in latitude 20° 55' Ν.,
    longitude 87° 50′ Ε.

  4. The following table shows the approximate
    track of the centre in the N.W. corner of the Bay.
    I have already indicated the course which it pursued
    after passing Balasore :-

12 midnight 20° 55' 87° 50′
3 a.m. 21° 8' 87° 45'

  1. At Saugor Island the wind had been steady all
    day from N.E., and did not veer until 12.30 a.m.,
    when it went round to E.N.E., which was probably
    the first cyclone current. It continued steady at
    E.N.E. until 3 a.m., veering between this and 5 a.m.
    to E.S.E., at which point it remained until 8.30 a.m.
    At 3 a.m. the barometer was lowest, and between
    this and 4 a.m. the centre was probably nearest.
    The "Madras," at anchor in Saugor Roads, ex-
    perienced the same winds and changes, and her
    barometer was lowest at 4 a.m. From midnight to
    3 a.m. the storm was moving nearly northwards and
    approaching Saugor. I have no observations from
    the "Meteor" from midnight to 4 a.m. The lowest
  • Land observations not printed herewith.
  1. The "Coldstream," running E.S.E. from
    1 p.m. on the 27th, encountered on the 28th and the
    morning of the 29th what appears to have been the
    southern quadrant of a cyclone. Her position is,
    however, unknown. At 1 a.m. on the 29th her
    course was changed to N. by E., and at 9 a.m. to
    N. by W. A south or S. E. course, if such had been
    possible, would then, apparently, have taken her
    completely out of the influence of the cyclone. She
    had a W.S.W. and S.W. by W. wind. At 9 a.m. the
    gale had moderated slightly, but at 1 p.m. was "in-
    creasing, with heavy rain and every appearance of
