Regional Meteo-climate modeling at different temporal scales: From the short to the long term.

In this talk a review of the experience acquired by the Mesoscale modeling and Climate groups at the University of L'Aquila (CETEMPS) in both research on mesoscale modeling (short and long term) and in the operational weather forecast, during the last 20 year in the Mediterranean area is presented. Most of the research activities discussed in this review concern a wide spectrum of weather- and climate-related issues at different temporal and spatial scales in complex topography. A brief review of the most important findings and of their application in the operational forecast is presented together with the role of data assimilation in the high-resolution weather forecast in complex topography. The merging of modeling expertise on the different spatial and temporal scales allowed for transferring the high-resolution modeling experience to the climate application at convection resolving scale, a few results will be briefly presented. Finally, indications for planning future studies in weather and climate spheres by using WRF model are suggested.
