Beskrivelse af klimaparametre/Climate element description

Tabellen nedenfor beskriver de klimaparametre, der indgr i denne rapport. Elementnummeret indgr i de forskellige datafiler p de datafiler, der flger med rapporten. Enheden der er knyttet til de forskellige parametre er den enhed, der er brugt i alle datafiler indeholdende mnedsvrdier. 
Bemrk at enheden i de datafiler der indeholder normaltal alle er 0,1. Metoden angiver, hvordan de forskellige klimavrdier er beregnet udfra de enkelte observationer, fr der midles til klima- eller provisoriske normaler.

The table below lists the climate elements described in this report. The element no. is the number by which the climate element is identified in the normal and monthly data files. The units in the table are the units used in the monthly data files. 
The units of the normals in the normal.dat data file are all 0.1. The method is the method applied to the daily values to obtain the monthly values, before calculating the average climatological or provisional normals.

Data may only be used with proper reference to the accompanying report (Cappelen, J., 2002. Danish Climatological Normals 1971-2000 for selected stations. DMI Technical Report No. 02-12).

Vindroser/Wind roses

Vindroser for 10 stationer i perioden 1971-2000 (perioden er stationsafhngig), er indeholdt i grafikfilerne <stationsnummer_periode>.wmf (WMF - Windows Meta File). De er samtidig vist p de efterflgende sider.

Wind roses for 10 stations in the period 1971-2000 (the period is dependent on the actual station) are contained in the graphic files <station number_period>.wmf (WMF - Windows Meta File). They are also shown on the following pages.

Forklaring til vindroser

Vindroserne prsenteret i det medflgende datast viser fordelingen af vindens retning og hastighed. Vindens retning er inddelt i 12 sektorer p hver 30 grader og der er ligeledes inddelt i hastigheds-klasser.  Den procentvise fordeling er tillige anfrt i en frekvenstabel under selve vindrosen.  Vr opmrksom p, at i denne frekvenstabel er vindstille defineret som vindhastigheder mindre end eller lig med 0,2 m/s og disse tilflde indgr ikke i statistikken! Det betyder bl.a. at beregningen af den totale middelvindhastighed godt kan vre hjere end den middelhastighed man traditionelt beregner, idet denne indeholder samtlige tilflde af vindstille.

Alle vindroserne i rapporten er p engelsk. Af den grund er vindrosen for 06052 Thyborn ogs vist i en dansksproget version.

Wind roses, explanation

The wind roses presented in the accompanying dataset show the distribution of wind direction and speed. The wind direction is divided into 12 sectors, each 30 degrees. Furthermore, the speed is divided into sub groups. The distribution in percent can also be seen in the frequency table just below the wind roses.  Please note that calm situations are defined as wind speed below or equal to 0,2 m/s, and that these situations are not included in the calculations. This means that the calculation of the total mean wind speed in the frequency table could be higher than a mean wind speed calculated in the conventional manner, as this takes all wind speeds (also calm) into account.

All the diagrams in this report are in English. For this reason, the wind rose for 06052 Thyborn additionally is shown in a Danish version.

Mnedsfiler/Monthly files

Tidsserier af mnedsvrdier (1971-2000) for alle stationer, der er beregnet normaler p i afsnit 3 til 8 , findes i filerne <elementnummer>.dat. Filerne er sorteret efter stationsnummer/elementnummer, r og mned (mned 13 er rsvrdien). Hver linie i filerne indeholder 1 mneds- eller rsvrdi. Enheden p de enkelte klimaparametre kan ses p side 24. Bemrk at Date - datoen for en hndelse - kun findes i filerne med ekstremvrdier (formatet er [mned][dag] fx 825 for 25. august). I tilflde af manglende data er mnedsvrdien blank og rsvrdien er ikke beregnet (bortset fra ekstremfilerne).


Time series (1971-2000) for all the stations presented in section 3 to 8 are contained in the files <element number>.dat. The files are sorted by station no./element no., year and month (month 13 gives the annual total). Each record in the files contains one monthly or annual value for one station/element no. The units of the values can be seen in the table on page 24. Please also note that the Date variable only exists in the files concerned with extreme values (format is [month][day], e.g., 825 for 25 August). In case of missing data, the monthly value is blank and the annual value not calculated (except in the extreme files).
