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.

4.2

Ambient Air & Soil Temperatures: Temperature readings obtained from the Saudi Aramco and PME local weather stations are as follows: Commentary Note: This information in this section can be used in Heating, Ventilation and Air Conditioning (HVAC) design - see SAER-5307, 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. 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: Determined by finding the lowest value of the daily mean temperatures over the entire period of records. Page 4 of 27

Document Responsibility: Environmental Standards Committee Issue Date: 17 May 2011 Next Planned Update: 17 May 2016

SAES-A-112 Meteorological and Seismic Design Data

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: Determined by finding the highest value of the daily mean temperatures over the entire period of records. 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.

Document Responsibility: Environmental Standards Committee Issue Date: 17 May 2011 Next Planned Update: 17 May 2016

SAES-A-112 Meteorological and Seismic Design Data

10 meters above grade in open terrain and reported as follows: Basic Wind Speed: Basic Wind Speed data are provided in terms of a 3-second gust expressed in SI 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.

Prevailing Wind Direction: The compass direction (N, NNE, NE, ENE, E, etc.) from which the wind blows the greatest percent of the time. Commentary 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 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.

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 ICC IBC 2006 or ASCE/SEI 7 - 05.

4.4

Earthquake Data Commentary Note: For more data and details refer to the Supervisor of the Civil 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. Commentary Note: SS and S1 values have been determined based on SAER-6089. They are to be used as per procedures in ASCE/SEI 7 - 05 and ICC IBC 2006 to calculate the design spectral response acceleration parameters.

SAES-A-112 Meteorological and Seismic Design Data

Peak Ground Acceleration (PGA): 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 Note: The PGA is not used for structural analysis/design purpose. It is used to address soil liquefaction. Note that for Seismic Design Category D and higher, the potential for soil liquefaction requires consideration of both site peak ground accelerations and earthquake magnitude. PGA may be determined based on a site-specific study taking into account soil amplification effect or, in the absence of such a study, PGA shall be assumed equal to SDS/2.5. SDS is the design, 5% damped, spectral response acceleration parameter at short period.

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).

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. Commentary Note: These values are used in the design of grounding and lightning protection systems. Page 7 of 27

SAES-A-112 Meteorological and Seismic Design Data

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: The mass of total suspended airborne particulate matter per unit volume of air. 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
