Definitions
This section defines the meteorological and seismic data presented in Tables 1 and 2 Commentary Notes in Section 4 suggest how Meteorological and Seismic Design Data are typically used.
4.1 Station Location and Elevation
Station Coordinates: The approximate latitude and longitude of the plant site in the geodetic units of degrees and minutes.
Note:
This information can be used in Heating, Ventilation and Air Conditioning (HVAC) design to determine the position of the sun at various times of the year.
Site Elevation: Approximate elevations are listed for Saudi Aramco sites and relative to sea level.
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.
4.2 Ambient Air and Soil Temperatures
Temperature readings obtained from the Saudi Aramco, and relevant meteorological and/or environmental center(s).
Note:
This information in this section can be used in Heating, Ventilation and Air Conditioning (HVAC) design, as well as other applications requiring ambient air temperature data.
Average Annual Temperature: An average of the daily temperatures for the year averaged over a number of years.

Meteorological and Seismic Design Data
SAES-A-112
Average Daily Maximum Temperature: An average of the daily temperatures for the hottest month averaged over a number of years.
Monthly Normal Maximum Temperature: The average of the maximum daily temperature recorded during the hottest month averaged over a number of years.
Average Daily Soil Temperature: The average daily soil temperature for the hottest month, measured one meter below grade, averaged over a number of years.
Note:
This value is used for underground 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.
Note:
This value is used for underground buried pipelines.
Lowest One Day Mean Temperature: Determined by finding the lowest value of the daily mean temperatures over the entire period of records.
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: Determined by finding the highest value of the daily mean temperatures over the entire period of records.
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 “Appendix B” are compiled from local weather stations where it is measured 10 meters above grade in open terrain and reported as follows:
Basic Wind Speed: For designs using ASCE/SEI 7-05, Basic Wind Speed data are provided in terms of a 3-second gust expressed in SI for 50-year mean recurrence intervals. For designs using ASCE/SEI 7-10, Basic Wind Speed data are provided for different mean recurrence intervals based on the Risk Category defined for the structure or project.
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.
Prevailing Wind Direction: The compass direction (N, NNE, NE, ENE, E, etc.) from which the wind blows the greatest percent of the time.
Note:
Since up to 16 points of direction (N, NNE, NE, ENE, E, etc.) may be used to describe the direction from which the wind is blowing, the directions given in Appendix “B” 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. The wind rose diagram shall not be used for determining the wind design pressures for structural design.
Wind Exposure Category: Wind exposure category reflects the ground surface irregularities at or near a particular site and proximity to the shoreline. Wind Exposure Category shall be calculated for each structure using the surface roughness definitions and evaluation procedure found in Chapter 26.7

of ASCE/SEI 7-10, except that Exposure Category D automatically applies if the structure is located 0.20 km or less from the shoreline. Wind Exposure Category B is not permitted at any site.
Offshore Stations: See SAES-M-005 for offshore wind loading criteria.
Note:
Wind exposure 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 SAES-M-100 or ASCE/SEI 7-10 Chapter 26.
4.4 Earthquake Data
For more data and details contact the Supervisor of the Civil and Structural Engineering Unit of CSD.
Short Period Acceleration (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.
Note:
SS and S1 values have been determined based on SAER-6089. They are to be used as per procedures in ASCE/SEI 7 to calculate the design spectral response acceleration parameters.
Peak Ground Acceleration (PGA): The peak ground acceleration in Tables 1 and 2 is the peak horizontal acceleration in bedrock associated with an earthquake having a 10 percent probability of exceedance in 50 years (i.e., 475 year average return period). Soil amplification factors (site coefficients) associated with the Site Class must be applied to determine the site (surface) peak horizontal ground acceleration.
The peak ground acceleration is the maximum acceleration experienced by the structure that is attached to the earth during the course of the earthquake motion.
Commentary Notes:
- The PGA is not used for structural analysis/design purposes.
- Assessment of the potential for soil liquefaction requires consideration of both site
peak ground acceleration and earthquake magnitude.
Site Class: A classification assigned to a site based on the types of soils present and their engineering properties as per ASCE 7-05 or ASCE 7-10 Site Classification, as applicable.

4.5 Precipitation
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).
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, 50 and 100 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 hour.
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.
Note:
These values are used in the design of grounding and lightning protection systems.
4.6 Ambient Air Quality
Ground level ambient air pollutants under extreme conditions shall be evaluated on case-by-case basis in view of the availability of representative ambient air quality records and/or result of air dispersion modeling simulation.
4.7 Meteorological and Oceanographic Data for Offshore Structures
Offshore Structures: For the design of offshore structures the wind, current and wave design data should be taken from SAER-5697 Arabian Gulf Hindcast Study and SAER-5565 Red Sea Hindcast Study.
