(c) - When was the instrument last calibrated ?
This instrument has not been calibrated since its installation
at Awali during 1938; however, checks of the accuracy of the instrument
have been obtained by two methods. The first was by cross-checking with
the Meteorological Officer at the Royal Air Force base during periods of
windy weather last winter. The Company was informed by telephone that
the instrument at Muharraq was recording the same wind velocities within
a few miles per hour as were being shown at the time on the Company's
instrument in Awali. The second method was by measuring the wind
velocities at the same location on the Company's Main Office roof by means
of a deflecting vane anemometer which is used by the Company's air-conditioning
mechanics to measure air velocities in air ducts. A comparison of the
average of these readings indicated accuracy within a few miles per hour.
(d) - Rough details of the exoosi^ re of the instrument, i.e tt the
nroylmitv of buildings, he ights of adjacent buildipggt etp,
I am attaching copies of the Company's drawings BRA-5887 and
BR-308. The latter shows the natural topography of the ground in Awali
and the location of the Company's building on which the anemometer is mounted.
The approximate location of the anemometer on the roof of the Cornpany s
office building is indicated on this drawing. Drawing BRA-5887
provides a larger scale representation of all the buildings now existing
in the near vicinity of the office building. The elevation of the top
of each of these buildings has been marked on this print. It is believed
that these two drawings will serve to provide the necessary details of the
exposure of the recording instrument.
In addition to the above there is attached copies of the wind
velocity records obtained by the instrument for the period 9th to 13th
June, 1950.
I am enclosing a copy of this letter to which is attached the
prints and photostatic copies of the wind velocity records, for courtesy
of transmission to the Ministry of Civil Aviation, or, if you prefer, for
transmittal direct to Mr.Gordon. The Photostat copies of the wind velocity
records my be retained by the Ministry but the Company would appreciate
the return' of Drawings BRA-5887 and BR-308 when they have served the
purpose for which supplied.
Yours very truly.
