| Zusammenfassung |
The interaction between breezes and synoptic gradient winds, and surface
friction increase in transition from sea to land can create persistent
convergence zones nearby coastlines. The low level convergence of moist air
promotes the dynamical and microphysical processes responsible for the
formation of clouds and precipitation.
Our work focuses on the winter seasons of 1998–2011 in the Eastern
Mediterranean. During the winter the Mediterranean sea is usually warmer
than the adjacent land, resulting in frequent occurrence of land breeze that
opposes the common synoptic winds. Using rain-rate vertical profiles from
the Tropical Rainfall Measurement Mission (TRMM) satellite, we examined the
spatial and temporal distribution of average hydrometeor mass in clouds as a
function of the distance from coastlines.
Results show that coastlines in the Eastern Mediterranean are indeed favored
areas for precipitation formation. The intra-seasonal and diurnal changes in
the distribution of hydrometeor mass indicate that the land breeze may
likely be the main responsible mechanism behind our results. |
