SAES-A-112
Meteorological and Seismic Design Data
Scope
This standard defines the basic meteorological and seismic data to be used in the design
of all Saudi Aramco facilities. These data are presented in tabular form in Appendix I.
Commentary Notes:
Saudi Aramco meteorological data generally are based on a minimum of 10 years of data.
However, where weather records are available, data have been based on longer periods;
where records are limited, data have been based on the maximum available time period.
As pertinent reference material becomes available, meteorological data for Saudi Aramco
installations will be revised and expanded.
This entire standard may be attached to and made a part of purchase orders.

Definitions
This section defines the meteorological and seismic data presented in Tables 1 & 2 and
indicates some of the areas in which these data are commonly used.
4.1
Site elevation and station coordinates: although not considered
meteorological or seismic data, are included in this standard for the convenience
of the user.
Elevation Above Mean Sea Level: Approximate elevations are listed for Saudi
Aramco sites and referenced to Mean Sea Level (MSL).
Commentary Note:
These elevations are used by process, equipment, and utility engineers for
calculation of atmospheric pressure. Seasonal site specific atmospheric pressure
is also available from the Environmental Protection Department.
Station Coordinates: The approximate latitude and longitude of the plant site
in the units of degrees and minutes.
Commentary Note:
This information can be used in HVAC design to determine the position of the sun
at various times of the year.
4.2

Meteorological and Seismic Design Data
Average Annual Temperature: An average of the daily temperatures for the
year averaged over a number of years.
Average Daily Maximum Temperature: An average of the daily temperatures
for the hottest month averaged over a number of years.
Commentary Note:
This value is used in the rating of transformers and electric motors.
Monthly Normal Maximum Temperature: The average of the maximum
daily temperature recorded during the hottest month averaged over a number of
years.
Commentary Note:
This value is used in the rating of transformers and electric motors.
Average Daily Soil Temperature: The average daily soil temperature for the
hottest month, measured one meter below grade, averaged over a number of
years.
Commentary Note:
This value is used for underground cable applications and buried pipelines.
Monthly Normal Maximum Soil Temperature: The average of the maximum
daily soil temperature, measured one meter below grade, during the hottest
month averaged over a number of years.
Commentary Note:
This value is used for underground cable applications and buried pipelines.
Lowest One Day Mean Temperature: This temperature is determined by
finding the lowest value of the daily mean temperatures over the entire period of
records.
Commentary Note:
An ambient temperature that may be required for the minimum design metal
temperature for equipment that is significantly pressurized at ambient
temperatures.
Highest One Day Mean Temperature: This temperature is determined by
finding the highest value of the daily mean temperatures over the entire period
of records.

SAES-A-112
Meteorological and Seismic Design Data
Commentary Note:
An ambient temperature that may be required to determine the maximum metal
temperatures used in the design of structures, piping systems and certain types
of equipment.
Lowest Recorded Temperature: The lowest ambient air temperature that has
been recorded at a particular site.
Highest Recorded Temperature: The highest ambient air temperature that has
been recorded at a particular site.
Summer Design Dry Bulb Temperature: A dry bulb temperature that has
been equaled or exceeded by 1%, 2.5% or 5% (30 hrs, 73 hrs, or 146 hrs) of the
total hours during the months of June through September.
Wet Bulb Temperature: The lowest temperature that can be obtained by
evaporating water into the air.
Mean Coincident Wet Bulb Temperature: The mean of all wet bulb
temperatures occurring at the specific Summer Design Dry Bulb Temperature.
Summer Design Wet Bulb Temperature: A wet bulb temperature that has
been equaled or exceeded by either 1% or 2.5% (30 hrs or 73 hrs) of the total
hours during the months of June through September.
Mean Coincident Dry Bulb Temperature: The mean of all dry bulb
temperatures occurring at the specific summer design wet bulb temperature.
Mean Daily Range: The difference between the average daily maximum and
average daily minimum temperatures during the month of August.
Winter Design Dry Bulb Temperature: A temperature that has been equaled
or exceeded by 99% of the total hours during the months of December, January
and February.
4.3
Wind: Wind data compiled from local weather stations are reported as follows:
Basic Wind Speed: The wind speeds are derived from local weather station
data. Both 3-second gust and Fastest Mile Wind Speeds are expressed in both
SI and customary units at 10 m above ground for 50-year mean recurrence
intervals.
Commentary Note:
This data is used for the design of structures, buildings, pressure vessels, piping,
storage tanks, air-cooled heat exchangers, cooling towers, stacks, and similar
equipment.

SAES-A-112
Meteorological and Seismic Design Data
Exposure Category: An exposure category reflects the characteristic of ground
surface irregularities at a particular site.
Commentary Note:
This category is used to account for large variations in ground surface roughness
that arises from natural topography and vegetation as well as from constructed
features. This factor is used in calculating wind pressures using either the IBC or
ASCE 7.
Prevailing Direction: The direction (N, NNE, NE, ENE, E, etc.) from which
the wind blows the greatest percentage of the time.
Commentary Note:
Since 16 points of direction (N, NNE, NE, ENE, E, etc.) are used to discuss wind
direction, the directions given in Table 1 could represent less than 10% of the
total time the wind is blowing. Where wind direction considerations are critical, a
wind rose diagram may be available from the Environmental Protection
Department.
4.4
Earthquake Data
Short Period Acceledation (SS): The mapped maximum considered earthquake
spectral response acceleration at a short period.
One-Second Period Acceleration (S1): The mapped maximum considered
earthquake spectral response acceleration at a period of 1-sec.
Commentary Note:
SS and S1 values have been determined based on SAER-5916. They are to be
used as per procedures in ASCE 7-02 and IBC 2003 to calculate the design
spectral response acceleration parameters.
Site Class: A classification assigned to a site based on the types of soils present
and their engineering properties as per IBC or ASCE 7 Site Classification Tables
1615.1.1 or 9.4.1.2 respectively.
4.5
Precipitation
Commentary Note:
The amount of precipitation (rainfall) is a factor used in storage tank design,
drainage design, waste-water discharge quality control, and similar items. It
should be realized that the desert climate and length of record make recorded
values highly variable (for example, Dhahran has 60 years of data while Tanajib
has 12 years).

Meteorological and Seismic Design Data
Rainfall, Average Annual: This is the annual average rainfall based on as
many years of data as available.
Rainfall Maximum in 24 Hours: This is the maximum precipitation recorded
in 24 hours.
Rainfall Intensity Coefficients: These coefficients are provided for return
periods of 5, 10, 25 and 50 years. The coefficients are used in the Steel Formula
[I = K/(t+b)] to calculate the average maximum precipitation rates for storm
durations up to two hours.
Where:
I
=
Rainfall Intensity in mm/hr (in/hr),
t
=
time of concentration in minutes, and
K & b are non-dimensional coefficients.
Isokeraunic Levels: A rough measure of lightning frequency.
Commentary Note:
These values are used in the design of grounding and lightning protection
systems.
4.6
Ambient Air Quality
Commentary Note:
Air-borne dust concentrations and contaminant levels are used in mechanical
equipment design, when sizing air filters and as a measure of potential dust
ingress in bearing housings, lube oil systems, etc.
Dust Concentration: Usual airborne dust concentration is 1 mg/m³. During
sandstorms, dust concentrations may reach 500 mg/m³. Particle sizes are as
follows:
95% of all particles are less than 20 micrometers
50% of all particles are less than 1.5 micrometers
Elements present in dust include compounds of calcium, silicon, magnesium,
aluminum, potassium, chlorides and sodium. When wetted (high humidity
conditions) these compounds function as electrolytes and can result in severe
corrosion.
Other pollutants present in the atmosphere under the most extreme conditions are:
H2S
Hydrocarbon
SO2
20 ppm (vol/vol)
150 ppm (vol/vol)
10 ppm (vol/vol)

and wave design data should be taken from SAER-2359 "Arabian Gulf Hindcast
Study", and SAER-5565 "Red Sea Hindcast Study".
If more precise data becomes available at a given site, it may be used for design
with the prior written approval of the Manager of Environmental Protection
Department, Dhahran.
