| Zusammenfassung |
| Climatological features of mesoscale rain activities over the Mediterranean
region between 5° W–40° E and 28° N–48° N are examined
using the Tropical Rainfall Measuring Mission (TRMM) 3B42 and 2A25 rain
products. The 3B42 rainrates at 3-hourly, 0.25°×0.25° spatial
resolution for the last 10 years (January 1998 to July 2007) are used to
form and analyze the 5-day mean and monthly mean climatology of rainfall.
Results show considerable regional and seasonal differences of rainfall over
the Mediterranean Region. The maximum rainfall (3–5 mm day−1) occurs
over the mountain regions of Europe, while the minimum rainfall is observed
over North Africa (~0.5 mm day−1). The main rainy season over
the Mediterranean Sea extends from October to March, with maximum rainfall
occurring during November–December. Over the Mediterranean Sea, an average
rainrate of ~1–2 mm day−1 is observed, but during the rainy
season there is 20% larger rainfall over the western Mediterranean Sea
than that over the eastern Mediterranean Sea. During the rainy season,
mesoscale rain systems generally propagate from west to east and from north
to south over the Mediterranean region, likely to be associated with
Mediterranean cyclonic disturbances resulting from interactions among
large-scale circulation, orography, and land-sea temperature contrast. |
