10 | Wind MEDCLIC 3.2 WIND NAMES When we talk about the wind direction we are referring to the coordinates from which it blows, not the ones it is heading to. To find out the coordinates the wind is blowing from we use a wind rose. A wind rose is a diagram which depicts the cardinal points, North, South, East and West. It also gives the intermediate points: northeast, southeast, southwest and northeast. They are sometimes found on maps to indicate their orientation. A wind rose marks the direction of the winds, which are named according to their direction. Depending on where a wind blows from it receives a specific name, which may vary according to the region. In the Balearic Isles winds are differentiated by the following names: Fig. 3.2 Tramuntana 0º - 360º TRAMONTANA Mestral 315º MAESTRALE NW N NE Gregal 45º GRECALE Ponent 270º PONENTE W E Llevant 90º LEVANTE Llebeig/Garbí 225º LIBECCIO SW S SE Xaloc 135º SCIROCCO Mig jorn 180º OSTRO
MEDCLIC / STUDENT Wind | 11 A.3.4. THE WIND ROSE Write the names on the wind rose: N NW NE W E SW SE S 3.3 THE WIND IN THE BALEARIC ISLANDS SOCIB has various weather stations spread out along the coast of the Balearic Islands so that it has information about the weather conditions at different points in the Balearic sea. These data are important when it comes to understanding swells and currents in coastal areas. Prevailing winds are those which blow most frequently in a particular area, even if they are not the strongest winds. On the Mediterranean coast the wind may vary depending on the location or the time of year because, just as the temperatures vary over the year, so do the winds. In the case of the Balearic Islands, the Tramontana is the prevailing wind, although depending on the time of year the wind is stronger or lighter. For example, during the summer months in the coastal areas of the Balearics thermal winds are produced, such as the sea breeze known locally as “Embat”. These winds are generated by the differences in temperature between the seawater and the land.
