Summary
[edit]
| Description |
English: Iso lines of annual rainfall (isohyetes) over the outlines of northern African countries (5°N to 25°N), only for rainfall values with relevance for the Sahel, from North to South: 50, 100, 150, 200, 300, 400, 500, 600, and 700 mm/a - filling with shades of blue and gray between 100 and 600 mm/a only, matching the predominant definition of the Sahel. Note that the lines are clipped in Eritrea (the East of Ethiopia does not belong to the Sahel) and that the shore of Arabia has been dropped. The repository of the data, geodata.grid.unep.ch, relates to FAO maps digitized in 1984. Not provided are the years averaged over and the interpolation procedure for rain-gauge and possibly satellite data.
Deutsch: Für die Sahelzone relevante Isolinien des Jahresniederschlags (Isohyeten) auf einer politischen Karte des nördlichen Afrika (5°N bis 25°N). Niederschlagswerte der Linien, von Nord nach Süd: 50, 100, 150, 200, 300, 400, 500, 600, and 700 mm/a, wobei die beiden Intervalle unter 100 bzw. über 600 mm/a nicht farbig gefüllt sind, entsprechend der überwiegenden Definition der Sahelzone. Die Isolinien sind in Eritrea abgeschnitten - der trockene Osten Äthiopiens gehört nicht zum Sahel. Arabiens Küste ist weggelassen. Das Repository der Daten, geodata.grid.unep.ch, gibt Karten der FAO als Ursprung an, digitalisiert 1984, aber nicht den Zeitraum, über den welche Daten wie gemittelt wurden. |
