SCIENTIFIC, ACADEMIC AND PROFESSIONAL PROFILE
References in brackets are made to the above short list of publications
I graduated in Physics in 1972 (Italian Doctor Degree) 110/110, Magna Cum Laude, with a thesis on the co-oscillation tides of the Adriatic Sea and the problem of Venice high tides.
After two years of research training in Geophysical Fluid Dynamics at Bologna University (1972-74) during which I entered into contact with Prof Green of Imperial College, London, I obtained a three-year Research Fellowship from the Royal Society which I spent at Imperial College, London, (1974-76) working on flow past isolated obstacles and synoptic and dynamics of lee cyclogenesis (1).
In 1977, at the invitation of the Federal Hydrometeorological Service of Jugoslavia, I spent two months visiting the Faculty of Mathematics and the Federal Weather Service in Belgrade, working on limited area meteorological modeling and exported the model HiBu to Bologna University, where it was extensively used and further developed for research and operations for two and a half decades.
In 1977, at the invitation of Prof Aksel Wiin-Nielsen, I joined the newly formed European Centre for Medium-Range Weather Forecasts as a Junior Scientist in the Analysis Section of the Research Department, where, together with Andrew Lorenc, I developed the algorithms and wrote the operational codes for the humidity analysis (2) and for the use of TEMP special levels.
After promotion to Scientist (1978) and to Senior Scientist (1980), I moved to the Numerical Aspects Section of the Research Department, where I started working on model representation of orographic forcing and its relation to the maintenance of long-term anomalies and to systematic model errors, developing with Adrian Simmons and Mike Wallace the concept of Envelope Orography (3, 4, 5, 9).
In 1983 I became Head of the new Numerical Experimentation Section of the Model Division, where I contributed to develop the early techniques of Model Experimentation into a consolidated technology and a scientific tool to investigate model errors as well as atmospheric processes and phenomena and used them to asses the ability/inability of GCMs to represent such processes/phenomena. Main objects of such investigations were, at this stage, the monsoon transitions and atmospheric blocking, together with the related model errors and deficiencies (8).
My interests in the mechanisms of maintenance of persistent atmospheric anomalies led me to concentrate some efforts into extended (monthly, seasonal) model predictions (12, 13, 14) and in the associated problem of the existence of atmospheric weather regimes (10, 11). Such pioneer efforts contributed to the merging of the two Diagnostic and Numerical Experimentation Sections of the Research Department into a new Diagnostic and Predictability Section, which I led from 1986. This line of development contributed greatly to develop operational seasonal forecasting at ECMWF.
During this period, together with Franco Molteni and Tim Palmer, I also started to investigate at ECMWF problems of predictability of forecast skill and of ensemble forecasting techniques (6, 7), which after some years and thanks to the contributions of many more ECMWF scientists, led to the current ECMWF EPS system.
In 1987 I returned to Italy, taking up an Associate Professorship first at Camerino University and then at Bologna University, where I also assumed the leadership of the Atmospheric Dynamics Group of Bologna (ADGB). Here, within the Physics Department, I continued my research on atmospheric blocking and its predictability (15, 16, 17), but mostly I concentrated on developing in an organised way academic training in meteorology, climatology and atmospheric sciences, within the Degree Courses in Physics and Environmental Sciences. I was later co-founder of the first Degree Course in Meteorology and Atmospheric Physics in Italy and of the first Master in Applied Meteorology, both currently held at Bologna University.
1996 represented a turning point in my professional career: I was asked to lead the transition of the Regional Meteorological Service (SMR) of the Emilia-Romagna Region from the Agricultural Department of the regional Government into the Regional Agency for Environmental Protection (ARPA). I obtained leave of absence from Bologna University to accept this post.
When I took up the position of Director of ARPA-SMR, the Service was a small regional agro-meteorological facility (although already well respected and of high scientific standard), counting 40 permanent staff. It had a network of approximately 30 automatic weather stations, one weather radar, and a budget of approximately 2 million €, entirely funded by the regional government, and it had a very limited (if any) national and international, scientific and operational, role and visibility.
From 1996 to 2008, ARPA-SMR has grown into the largest regional Hydro-Meteorological service of Italy. Today it can count on 75 permanent staff and approximately 20-25 fixed-term staff (mostly on EU-funded R&D contracts) and has a budget of approximately 8 million €, more than 35% of which comes from the commercial sale of data and services and from externally funded activities. ARPA-SMR has a network of approximately 400 met/hydromet automatic weather/hydro stations, one completely automatic radiosounding station and two C-band, Doppler, dual-polarisation, weather radars. It runs an Oracle-based meteorological archiving system which contains observed and model data since 1985 and historical data since early 1900 and which can be accessed freely from all regional users on the regional intranet, via a browser interface.
Under my guidance, ARPA-SMR developed its numerical weather prediction facilities to the point of becoming Regional Reference Centre in Numerical Weather Prediction of the National Civil Protection HydroMet Information System. ARPA-SMR is responsible for running the national LAMI Operational Suite (the Italian COSMO-Lokal-Modell operational suite, managed in close collaboration with AM-UGM) and one of its most distinguished scientists (Tiziana Paccagnella, head of Numerical Modelling at SMR) has recently been nominated International Scientific Manager of the COSMO Consortium.
More recently, ARPA-SMR has conceived and developed COSMO-LEPS, a novel approach to a Limited-area Ensemble Prediction System for intense meteorological events which is the first such system to having developed operational capabilities in Europe (18, 19, 20,23).
