The article focuses on the characteristics of air temperature and dew point changes observed
during repeated fog events in the Absheron Peninsula in 2000...2022. For this purpose,
continuous observation data of Heydar Aliyev International Airport was used. Here is an
analysis of all types of fog by month of occurrence. The limits of total fog, Meteorological
Optical Range ≤ 500 m. and 501...1000 m. are considered in the analysis. Repeating such
criteria, attention was paid to the recorded air temperature and dew point indicators for
I...III, IV...VI and X...XII months of the year. The analyzes show that the fogs observed in the
peninsula are mostly recorded at a temperature of 6...8 0C. The most commonly observed dew
point temperature ranges of 0,0...0,3 0C and 1,0...1,2 0C at all ranges of MOR in fog repeats.
The results of the research are of particular importance for the planning of the work of all
transport areas and the forecast of fogs.
Keywords: fog, meteorological optical range (MOR), air temperature, dew point temperature, automatic
weather station, physical-meteorological analysis.

INTRODUCTION
Recurrence of fog events is observed with
decreasing Meteorological Optical Range (MOR)
(Huseynov N.Sh.,2011, Guliyev H.I. et al, 2004).
This atmospheric phenomenon poses a threat
to agriculture and transport. Reduced visibility
creates difficulties in driving a vehicle, and as a
result, accidents are inevitable (Tanriverdiyev X.K.
et al, 2015, Mehdiyev A.S. et al, 2008). The area of
transport where fog events pose a greater threat is
air transport. Loss of horizontal visibility paralyzes
the operation of air transport. This violates the
minimum visibility of aircrafts, does not allow them
to take off and land on the runway, free movement
and approach to the stop (Tanriverdiyev X.K. et al,
2015, Huseynov N.Sh., 2011, Mehdiyev A.S. et al,
2008). On 27.03.1977, which went down in history
as the «Tenerife airport tragedy», the failure to
track the movement of two aircrafts on the runway
resulted in the tragic loss of 583 passengers on both
aircrafts. There are many such facts in the history
of air transport (Mammadova G.A., 2017). For this
reason, the constant repetition and study of fog
events is important for the safety of transport.
The phenomenon of fog is characterized
by the loss of meteorological visibility due to the
accumulation of sublimation and condensation
products in the atmospheric layer near the surface
of the earth in calm weather conditions, at certain
temperature and dew point limits. The warning
received by the Civil Aviation Authority due to
the reduction of the horizontal visibility distance
(SPECİ) is issued when the limits of 1000, 850,
550, 300, 150, 75 m are exceeded. At this time,
the control body and the staff controlling the
aircraft, according to the accepted criteria, make an
important decision for the flight with the help of
the equipment.
In order to study the occurrence of fog, its
physical properties are studied. The dependence
of fog on other meteorological parameters, the
change of its appearance and other meteorological
elements in its different extremes are constantly
attracting attention.

N. Sh. Huseynov. N. Sh. Huseynov extensively
studied the physical and geographical features
of the recurrence of fog events at the airports
of Azerbaijan, and focused on the role of other
meteorological factors in their formation.
However, the conducted research should be
constantly updated and modernized. The
increase in the number of observations, the
development of scientific and technological
tools for the statistical registration of fogs makes
it necessary to take such steps (AAR-ANS-008

in the country. In addition to small aviation, in
order to increase the activity of international
and local air flights, the safety of flights must be
ensured first.
The Absheron water area has a complex
physical-geographical position (Andersen H. et al,
2020, AAR-ANS-008 Meteorological service to
air traffic). Cold, dry, humid air masses coming to
the area from the north, south and east throughout
the year and the Caspian Sea determine the
synoptic conditions of this area (Tanriverdiyev
X.K. et al, 2015, Kanchan, L. et al, 2022). Also,
during the transitional periods of the year, fog
formation occurs in this region in clear weather
conditions and with the intervention of southern
air masses in the region. Depending on the type
of fog that occurs on the Absheron Peninsula,

regardless of the MOR threshold, recurring fog
events in January, February, and March were
mostly recorded in the 6...8 0C air temperature
range. In addition, 94 % of the total reproduction
occurred in the air temperature conditions of

the dew point observed during the fogs that
occurred in the I...III months were calculated.
Analyzes show that 51 % of fogs in cases where
MOR is ≤ 501m are formed under 0 0C, 27 % at

If we focus on the different air temperature
thresholds recorded during fog recurrences in
April, May and June, in the phase when MOR
is below 500 m, 24 % of total recurrences are
8...10 0C, 21 % are 10...12 0C, 20 % 6...8 0C, 11 %
12...14 0C, 8 % 16...18 0C, 7 % 4...6 0C. At other
extremes of air temperature, fog recurrences are
not higher than 3%, and this accounts for 9 % of
the total cases. However, at MGM ≤ 501 m, 91 %
of the total fog events in the 4...14 0C range were
repeated (Figure 2).
In April, May, and June, 24 % of repeated
fog events within ≤1000 m of MOR were observed
at temperature limits in the range of 8...10
and 10...12 0C, 23 % were 6...8 0C, 12 % were
12...14 0C, 6 % were 14...16 0C. In the range of
2...6 0C (5 %) and 16...22 0C (6 %), fog recurrences
accounted for 11 % of all cases. However, 89 %
of the total replication occurred in the 6...16 0C
range.

For both MOR thresholds, the highest
fog recurrences occur in the temperature range of
6...12 0C. The analysis of dew point thresholds
observed during fogs during these months is also
of interest. The analysis shows that more fog
cases (57 %) were recorded at 0.0 0C or closer to
the MOR visibility limits below 500 m. During
fog, the visibility distance of less than 500 m
was repeated in 25 % of cases in the range of
0,1...0,3 0C, and in 9 % of cases in the range of
1...1,2 0C. Fog recurrences at other dew point
thresholds did not exceed 3 %. 91 % of the
total repeatability was recorded in the range of
0...0,3 0C and 1,0...1,2 0C, and 9 % in other dew
point ranges.

53 % of this visibility threshold is
observed at 0 0C, 27 % at 0,1...0,3 0C, 11 % at
0,4...0,6 0C, and 5 % at 1,0...1,2 0C dew point
thresholds during the MOR threshold in the range
of 500...1000 m. Only 4 % of the occurrence of
the total ≤1000 m MOR limit occurred in the
dew point ranges of 0,7...0,9 0C, 4...4,2 0C, and
5,9...6,1 0C. 96 % of cases where MOR is below
500 m are recorded in dew point cases of 0...0,6
and 1...1,2 0C.
During fog in October, November
and December, 15 % of cases of MOR below
500 m have air temperatures of 6...8 0C, 13 %
of 12...14 0C, 12 % of 2...4 0C, 8...10 0C and
10...12 0C , 9 % were recorded in the range of 4...6 0C,
7 % in the range of 0...2 0C and 14...16 0C, and
6% in the range of 16...18 0C. In the range of
-2...0 0C, 18...20 0C and 20...22 0C, 7 % of the
total cases of MOR below 500 m are repeated.
The general repeatability shows that 93 % of
cases where MOR is ≤ 500 m during fog occur in
the air temperature range of 0...16 0C, especially
in the range of 6...12 0C (52 %).
In these months, 18 % of the cases of
MOR observed at ≤1000 m during fog were
6...8 0C, 16 % 2...4 0C, 14 % 8...10 0C, 12 %

temperature range of -2...0 0C, 16...18 0C and
20...22 0C, this indicator is only 5 % of the total
repeatability. However, 95 % of the repetition
of this appearance threshold was found to occur
in the range 0...16 0C, especially in the range

In recurring fogs in October, November,
and December, 58 % of cases where MOR
was ≤500 m had a dew point of 0 0C, 21 %
0,1...0,3 0C, 13 % 1...1,2 0C, 7 % 0,4...0,6 0C

in the 0...0,6 0C and 1,0...1,2 0C dewpoint range,
especially in the 0,0...0,3 0C (79 %) dewpoint range.
During these months, 48 % of 501...1000 m
MOR thresholds recorded during fogs were
repeated at 0,0 0C, 20 % at 0,1...0,3 0C, 14 %
at 0,4...0,6 0C, and 12 % at 1,0...1,2 0C dew

was found in the dew point ranges of 0,7...0,9 0C,
1,3...3,0 0C and 5,0...5,2 0C. However, 82 % of

In the study, phase I of maximum cases of
MOR below 500 m in annual repeated fog events
from 2000 to 2022 is located in the range of air
temperature 0...10 0С and dew point 0,0 0 C (Table 4).
0,1...0,3 0С dew point and 0...10 0С range of
air temperature is maximum phase II when MOR
≤500 m is observed during fog. The dew point
range of 1,0...1,2 0С and the temperature range of
0...10 0С is phase III where the maximum of MOR
is observed below 500 m. A total multiyear MOR
of less than 500 m was observed in 3,668 cases.
During the multi-year period of fog, the
first phase in which the cases of MOR recorded
at the range of ≤ 1000 m were repeated more often
occurred in the conditions of air temperature
0...14 0С and dew point 0,0 0С (Table 5).
The second phase, where this appearance
threshold is more repeated, is the temperature
range of 2...12 0С and the dew point range
of 0,1...0,3 0С. The third maximum phase, in
which the limit of MOR ≤1000 m is repeated,
coincides with the approximate range of dew
point 1,0...1,2 0C and temperature 2...12 0С.

Hydrometeorology and ecology №2 2024
A total of 501...1000 m MOR occurred
in 1333 cases in the multiyear period. Given the
small numbers of repeated occurrences during
fog in the tables, it can be said that the main fog
occurrences occurred at temperatures of 6...8 0С
and dew points of 0,0 0C at both analyzed MOR
thresholds.
CONCLUSION
The following results were obtained
during the study of the dependence of MOR
on air temperature and dew point thresholds
during repeated fogs in Absheron Peninsula in
2000...2022:
1. In January, February, March, 75 % of
cases of MOR below 500 m have an air temperature
of 2...10 0C, in April, May, June, 76 % of cases are
6...14 0C, and in October, November, December,
60 % It happened in the range of 4...14 0C.
2. In January, February, March, 85 % of
cases of MOR below 501...1000 m air temperature is
2...10 0C, in April, May, June 83 % is 6...14 0C,
and 67 % in October, November, December It
happened in the range of 2...12 0C.
3. All MOR thresholds for year-round
recurring fog occur in the dew point ranges of 0.0
0
C, 0,1...0,3 0C and 1,0...1,2 0C.
4. During fog, the maximum repetition of
both MOR thresholds occurs at 0,0 0C dew point
conditions with temperatures of 6...8 0C.
The analyzes of the fogs occurring in the
Absheron water area are used for future forecasting,
air transportation planning, charting, etc. can be
used in the assessment of the logistics interests of
the state and in the planned organization of the
work of transport types.
In the conditions of modern climate
changes, the process of increasing the temperature
of the air and decreasing the amount of precipitation
continues on the Absheron peninsula. In such
conditions, air humidity is also decreasing. Our
analysis shows that global warming will weaken
the recurrence of fog events on the Absheron
Peninsula, leading to internal shifts in its timing.
Therefore, it is recommended to give priority to
the use of regional forecast models in which the
local relief factor is taken into account in fog
forecasting.

В статье рассмотрены особенности изменения температуры воздуха и точки росы, наблюдавшиеся во время повторных туманов на полуострове Абашерон в 2000...2022 гг. Для
этого были использованы данные постоянного мониторинга Международного аэропорта
им. Гейдара Алиева. В анализе учитываются пределы общего тумана, дальность метеорологической видимости (ДМВ) ≤ 500 м. и 501...1000 м. При повторении таких критериев
обращали внимание на регистрируемые показатели температуры воздуха и точки росы
для I...III, IV...VI и X...XII месяцев года. Анализы показывают, что наблюдаемые на полуострове туманы в основном фиксируются при температуре 6...8 0С. Наиболее часто наблюдаемые температуры точки росы во всех диапазонах ДМВ в повторах тумана находятся в пределах 0,0...0,3 0С и 1,0...1,2 0С. Результаты исследования имеют особое значение
для планирования работы всех транспортных направлений и прогнозирования туманов.
Ключевые слова: туман, дальность метеорологической видимости (ДМВ), температура воздуха, температура точки росы, автоматическая метеостанция, физико-метеорологический анализ.
