Abstract. By studying a horizontal distribution of relative humidity of
the Haram area between December 11
th
and 31
st
(including days
before, during and after Haj period), it was found that the changes in
humidity inside and outside the Haram area did not exceed 4% for the
same period, while on other days the difference between inside and
outside the Haram area was 1%. The reason for these differences
might be referred to the natural geography of the Haram area (very dry
desert nature), as well as, weather conditions (starting winter season).
All the stations around Haram showed that the humidity
measurements attained its highest value of 72% on both 30
th
and 31
st
December and with southerly winds between 1-3ms
-2
, while lower
values of 20% were measured on both 22
nd
and 23
rd
December with
southerly winds between 4.5-7.5ms
-2
. After analysing the air
temperature measurements for the Haram area, a large difference in air
temperature inside the Haram and outside area was found (2˚C). This
is probably because of the extreme difference in the nature of the
ground surfaces inside Haram and the area around, in addition to
human activity and weather conditions. |
