Synoptic case-study of spring rains in Eritrea

  • Assefaw Habtemichael

Synoptic analyses at sea-level, 850, 700, 500 and 250 mb have been used to examine the origin of a spell of rains in Eritrea during April 1970. A strong southward bend in the sub-tropical jet stream to 10° N seems to have provided a mechanism for the temporary development of deep convection clouds, fed by moisture from lower tropospheric south-easterly winds flowing across the southern Red Sea.

Synoptische Untersuchung eines Frühjahrsregens in Eritrea


Auf Grund von synoptischen Analysen der Bodenwetterkarten und der 850-, 700-, 500- and 250mb-Karten wird die Ursache einer Regenperiode im April 1970 in Eritrea untersucht. Eine starke Ausbiegung des subtropischen Jetstreams nach Süden bis 10° N hat anscheinend die Vorbedingung für die Entwicklung mächtiger Konvektionswolken geschaffen, die von der Feuchtezufuhr durch südöstliche Winde, die das südliche Rote Meer in der unteren Troposphäre überstreichen, gespeist werden.
