Die Daten basieren auf einer schweizweiten Modellierung mit einer horizontalen Gitterweite von 100 m. In der Karte ist für jeden Gitterpunkt der modellierte Jahresmittelwert der Windgeschwindigkeit dargestellt. Die Verteilung der Windgeschwindigkeiten in Windgeschwindigkeitsklassen kann mit den Weibullparametern A (Skalenparameter) und k (Formparameter) angenähert werden. Aus den Weibullparametern kann nicht direkt auf den Mittelwert der Windgeschwindigkeit geschlossen werden, da es sich um eine Annäherung an eine Windverteilung handelt und diese nicht für jeden Standort ausreichend wiedergegeben werden kann. Die Windrose zeigt die relative Häufigkeit der modellierten Windrichtungen. Pro Sektor sind die gemittelten Windgeschwindigkeiten und zugehörigen Weibullparameter ersichtlich. Für die Berechnung der Windgeschwindigkeiten und Windrichtungen sind langjährige Messungen in die Modellierung eingeflossen. Da die Messpunkte schweizweit nicht überall in einer angemessenen Dichte vorhanden sind und Ungenauigkeiten bei der Modellierung von Windströmungen im komplexen Gelände auftreten, sind die Resultate mit Unsicherheiten behaftet. Die Grössenordnung der Unsicherheiten liegen im Jurabogen bei bis zu +/- 0.5m/s, im Mittelland bei bis zu +/- 0.7m/s, in den Voralpen bei bis zu +/- 0.5m/s und in den Alpen bei bis zu +/- 1.3m/s. Für die Karten ab 100m Höhe über Grund stehen markant weniger Messungen für die Modellierung zu Verfügung. Dies resultiert in einer höheren Unsicherheit der Ergebnisse. Die Angaben sind als grobe Einschätzung der Windverhältnisse zu verstehen. Bei Interesse an einer Standortentwicklung ist eine Messung vor Ort unumgänglich.&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;font size='4' style='font-family: inherit;'&gt;&lt;b&gt;English&lt;/b&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;The Wind Atlas of Switzerland describes the wind conditions at five different heights above the ground: 50, 75, 100, 125 and 150 metres. The data are based on a nation-wide modelling system with a horizontal grid width of 100 metres. The modelled average annual wind speed is depicted in the atlas at each grid point. The classification of wind speeds into categories can be approximated with the aid of Weibull parameters A (scale parameter) and k (shape parameter). It is not possible to directly derive the average wind speed from the Weibull parameters because the result is only an approximation to wind distribution and this cannot be adequately reflected for each location. The wind rose shows the relative frequency of the modelled wind directions. The averaged wind speeds and corresponding Weibull parameters are visible for each sector. The calculation of wind speeds and directions is based on long-term measurements that have been incorporated into the models. Because the measurement points are not available everywhere throughout the country at a suitable density, and inaccuracies can occur in the modelling of wind flows in complex terrain, the results are subject to uncertainties. These range from +/- 0.5 metres per second in the Jura range, +/- 0.7 metres per second in the central plain and +/- 0.5 metres per second in the pre-Alps, to +/- 1.3 metres per second in the Alps. For maps at heights of more than 100 metres above the ground, significantly fewer measurements are available for modelling purposes, and this leads to increased uncertainties in the results. The data have to be regarded as rough estimates of the wind conditions. To assess the wind conditions at a specific location, measurement on site is therefore essential.&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;font size='4' style='font-family: inherit;'&gt;&lt;b&gt;Francais&lt;/b&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;L'Atlas des vents de la Suisse décrit les conditions de vent à cinq hauteurs au-dessus du niveau du sol (50, 75, 100, 125 et 150 m). Les données se fondent sur une modélisation au niveau national avec un maillage horizontal de 100 m.Sur la carte, la moyenne annuelle modélisée de la vitesse du vent est représentée pour chaque maille. La distribution des vitesses du vent en différentes catégories peut être approximée grâce aux paramètres de Weibull A (paramètre d'échelle) et k (paramètre de forme). La valeur moyenne de la vitesse du vent ne peut pas être déduite directement des paramètres de Weibull, car il s'agit d'une approximation d'une distribution du vent et qu'elle ne peut pas être reproduite de manière suffisante pour chaque site. La rose des vents illustre la fréquence relative des directions modélisées du vent. Les vitesses du vent calculées et les paramètres de Weibull qui s'y rapportent sont indiqués par secteur. Pour calculer la vitesse et la direction du vent, on intègre à la modélisation les données de mesure sur plusieurs années. Comme les stations de mesure ne sont pas réparties avec la même densité sur tout le territoire et que des inexactitudes apparaissent lors de la modélisation de la circulation du vent sur des reliefs complexes, les résultats ne sont pas entièrement fiables. L'incertitude varie de ± 0,5 m/s dans l'Arc jurassien, de ± 0,7 m/s sur le Plateau, de ± 0,5 m/s dans les Préalpes et de ± 1,3 m/s dans les Alpes. Les mesures disponibles pour la modélisation sont nettement moins nombreuses pour les cartes d'une hauteur de 100 m ou plus au-dessus du niveau du sol, ce qui engendre des résultats encore plus incertains. Les indications représentent une estimation grossière des conditions de vent. En cas d'intérêt pour développer un site, il est indispensable d'effectuer des mesures sur place.&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;font size='4' style='font-family: inherit;'&gt;&lt;b&gt;Italiano&lt;/b&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;L'atlante eolico svizzero descrive le condizioni di vento a cinque diverse altezze sopra il livello del terreno: 50 m, 75 m, 100 m, 125 m e 150 m. I dati si basano su una modellizzazione dell'intero territorio nazionale che utilizza una griglia con punti di ampiezza orizzontale pari a 100 m. Sulla carta viene riportato per ogni punto della griglia il valore medio annuo della velocità del vento calcolato attraverso la modellizzazione. La distribuzione delle velocità del vento secondo differenti classi può essere stabilita con approssimazione attraverso i parametri A (parametro di scala) e k (parametro di forma) della distribuzione di Weibull. Tali parametri non permettono di calcolare direttamente il valore medio della velocità del vento bensì solo un'approssimazione della distribuzione del vento, la quale non può essere rappresentata in modo sufficiente per ogni luogo. La rosa dei venti mostra la frequenza relativa delle direzioni del vento ricavate sulla base della modellizzazione. Per ogni settore sono visibili le velocità medie e i corrispondenti parametri di Weibull. Per la modellizzazione alla base del calcolo delle velocità e delle direzioni dei venti ci si è serviti delle misurazioni di diversi anni. Poiché la densità dei punti di misurazione presenti sul territorio svizzero non è sempre adeguata e in alcune zone caratterizzate da condizioni complesse la modellizzazione delle correnti dei venti presenta imprecisioni, i risultati sono affetti da incertezza. L'incertezza non supera l'ordine del +/- 0,5m/s sul Giura, +/- 0,7m/s nell'Altipiano, +/- 0,5m/s sulle Prealpi e +/- 1,3m/s sulle Alpi. Per le carte relative ad altezze che partono dai 100 m sopra il livello del terreno si dispone di un numero notevolmente inferiore di misurazioni necessarie alla modellizzazione, il che determina un maggiore grado di incertezza dei risultati. I valori forniti sono da ritenersi una stima approssimativa delle condizioni di vento, pertanto qualora vi sia l'interesse a sviluppare un progetto in una determinata ubicazione non si può prescindere da misurazioni in loco.&lt;font size='4' style='font-family: inherit;'&gt;&lt;br /&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='font-family: &amp;quot;Avenir Next W01&amp;quot;, &amp;quot;Avenir Next W00&amp;quot;, &amp;quot;Avenir Next&amp;quot;, Avenir, &amp;quot;Helvetica Neue&amp;quot;, sans-serif; font-size: 16px;'&gt;Stand: August 2019&lt;/div&gt;</idAbs>
