Wind direction is the sky, the side from which the wind is blowing. Wind speed is the average wind speed in a small period of time (usually 2 or 10 minutes). Maximum gust is the highest instantaneous wind speed. tables 13 and 14 data calculated over a 30-year fixed VM period (1961-1990), 15-table data for the entire period in which the gain of each station representative data. Wind observations in meteorological stations make 10-12 m from the ground. 15. the table referred to in months and the annual maximum wind speed and wind gust clay charge on all relevant observation period (up to and including 2003) each and every wind speed gauge the actual location and height. "; 1.8. to supplement annex 2 et seq of 14.1 and 14.2 points as follows: 14.1 1.1 image. " The fundamental value of wind pamatātrum at each point in the set of observed mu, with information about each year's maximum average wind speed over a period of 10 minutes regardless of the wind direction and season. Each year's maximum wind speed value is recalculated to a height of 10 metres above the flat, open countryside with area roughness length zo 0.05 m. Recalculation is performed according to the World Meteorological Organization proposed methodology. Wind with a probability of pamatātrum 0.02 (once every 50 years) calculated using Gumbel probability distribution. 14.2 1.2 image. Wind pressure values determined in accordance with the standard EN EN 1991-1-4 4.1 and 4.10 above formula. Direction factor cdir, seasonal factor cseason value under the standard LVS EN 1991-1-4 recommendations is 1.0. Air density value in accordance with the recommendations of that standard is 1.25 kg/m3. " 1.9. to supplement annex 2 et seq to 15.1, 15.2, 15.3 and 15.4 points as follows: 16.1, 16.2, 16.3 "15.1 and 16.4 table 2.1 and Figure 2.2 and in snow loads on the surface and related statistical information calculations made 32 observation points in all Latvian climatic zones, with single 54 winter data (from 1950-1951 winter until the 2003-2004 winter). At each observation point in the snow loads used to calculate the data for each winter the maximum amount of water in the snow, the snow cover in the uzmēr field in the route. The calculation was made using the Gumbel probability distribution. 15.2 16.2 tables and Figure 2.2 possible in exceptional snow load values on the surface in all 32 observation points calculated as assignment that created daily observations for the heaviest to date found the snow with the most snow cover for the tilpumsvar inherent in the wet snow (the standard LVS EN 1991-1-1-3 "Euro code effects on structures. -Part 1-3: General effects-snow load "E E table 1 in annex). In virtually all climatic areas of Latvia the following estimated snow load is 1,8-2 times the snow load on the ground surface characteristics in question worthwhile (with a probability of once every 50 years). Thus, the Latvian climatic conditions in all its districts can use the standard LVS EN 1991-1-3 in point 4.3 proposed exceptional snow load coefficient of 2.0. In accordance with the standard EN 15.3 EN 1991-1-3 (D), using the formula (D). 1., snow load on the ground surface can be adjusted to suit the intrinsic values in any recurrence period that is different from the characteristic value of snow load with a probability of 0.02 (once every 50 years). According to the calculation can be performed using the information listed in table 16.3 for the winter period the maximum snow load coefficient of variation for each observation point. 15.4 16.4 the table provides information about the snow load on the ground surface in characteristic values with a probability of once every 150 years. This period corresponds to the Uptown, their design elements, finish (also the roof load-bearing elements) for the longest mean lifetime. The calculation was made using the Gumbel probability distribution. " 2. Construction plan which duly accepted or submitted for acceptance to the date of entry into force of the provisions and technical solutions which correspond to the period of the existing regulatory requirements are not to be processed according to the requirements of this regulation. 3. The entry into force of the provisions by 1 November 2005.
