Characteristics of wind fields and air-sea interactions over the upwelling region of the Somali coast

The mesoscale structure of the low-level wind field associated with a strong upwelling event was investigated. During July 2005 when a strong upwelling event occurred, the Somali jet was found to have oscillated at lower frequency of 3-7 weeks than the normal bi-weekly mode observed in several studies and the mesoscale winds exhibited high covariability with the prevailing SSTs. Strong values of alongshore winds were deduced from late June to mid-July. These winds weakened significantly in the third and fourth week of July. A large off-shore pressure gradient due to differential thermal properties of land and sea was also observed.
