Two years of TOPEX/POSEIDON altimeter data have successfully been used to study the mesoscale field in the Mediterranean and to investigate the seasonal and year-toyear variability of the sea level and eddy statistics in this basin. The mesoscale field described by TOPEX/POSEIDON revealed a strong, but subbasin dependent, seasonal signal. Year-toyear variations are also evident in terms of both...

The BSC-CNS is involved in the CALIOPE project (Baldasano et al., 2008), a national Spanish initiative that has as main objective to establish an air quality forecasting system for Spain coordinated by the Ministry of the Environment. The modeling system bases on the WRF-ARW model as meteorological driver (Figure 1). As is well known, air quality models are highly dependent on the quality of th...

Five characteristic, low-level, large-scale dynamical patterns associated with tropical cyclogenesis in the western North Pacific basin are examined along with their capacity to generate the type of mesoscale convective systems that precede genesis. An 8-yr analysis set for the region is used to identify, and create composites for, the five characteristic patterns of monsoon shear line, monsoon...
