  1. Abstract. “The analog ensemble system and its applications”: In the last few years, the analog ensemble (AnEn) technique has been extensively tested for a wide range of applications ranging from renewable energy to meteorological reanalysis. It provides accurate deterministic estimates and reliable uncertainty quantification by generating an ensemble from a deterministic prediction and a historical data set including observations of the quantity to be predicted and predictions from the same system. The AnEn has been applied to generate both short-term predictions and multi-year resource assessments of wind and solar power, rainfall reanalysis dataset and gridded meteorological predictions, among others. Examples of these applications will be shown with an analysis of both deterministic and probabilistic skills. For the former, traditional metrics as root-mean-square-error, bias, correlation, and mean absolute error will be examined, whereas important attributes of probabilistic predictions as statistical consistency, reliability, sharpness, resolution, and spread-skill relationship will be assessed for AnEn and the methods to which it is compared. Some of the recurring features of AnEn across the different applications are:
    • Reduction of systematic and random errors and an increase of the correlation between the predictions and the observations with respect to the deterministic prediction used to generate AnEn;
    • The possibility of using a higher resolution model (since only one deterministic forecast is needed to generate an ensemble);
    • No need for initial condition and model perturbation strategies to generate an ensemble;
    • Intrinsically reliable estimates (i.e., no postprocessing required);
    • Ability to capture the atmospheric flow-dependent error characteristics;
    • Superior skill in predicting rare events when compared to state-of-the-science post-processing methods and traditional ensemble methods based on a set of numerical weather predictions.
  2. Abstract. “Lagrangian measurements in the atmospheric boundary layer and inside warm clouds by means of clusters of mini radio probes“: Clouds determine precipitation and constitute the main compo- nent of the hydrological cycle. They can be very beautiful, but also emphemeral in the eyes of people, artists, but also of scien- tists, thereby creating a fascina- ting enigma. The scientific study of clouds be- gan with Luke Howard’s classification in 1803. Throughout the 19th century, the boundary between the arts and sciences, particularly with regard to natural sciences, including meteorology, was much less rigid than it is today. For instance, the great German poet Goethe took particular interest in the scientific classification of clouds. The most original sea-and-sky scape painter of the 19th century, JWM Turner, annotated his copy of Goethe’s ‘Theory of Colors’, and referred to it directly in the title of one of his paintings (Light and color (Goethe’s theory)—The Morning After the Deluge—Moses writing the book of Genesis (The Tate Gallery, London)). And one the finest of all cloud painters, John Constable, was also well aware of the work of Luke Howard, and performed detailed cloud studies in the 1820s over Hampstead Heath. It is now understood that, paradoxically, the global dynamics of the atmosphere and climate are very much dependent upon the microscale-level processes of clouds. In fact, in addition to convective heating due to the latent heat release associated with the condensation of water vapor, clouds control, to a large extent, the solar and thermal radiation balances of the atmosphere. The present seminar course mainly focuses on a few of the fundamental aspects concerning clouds:
    • The condensation of water vapor and the subsequent precipitation within clouds through microphysical processes that take place at cloud particle size scales, ranging from several micrometers to a few centimeters.
    • The development of improved observational techniques to study microphysical processes and bulk cloud properties and to measure the physical and optical properties of atmospheric aerosols.

Seminario di Meteorologia Ambientale a cura di Claudia Acquistapace

L’Istituto di Geofisica e Meteorologia dell’Università di Colonia ha annunciato che il prossimo Giovedì 25 maggio 2023, alle ore 14:30 (ora italiana) si svolgerà il seminario dal titolo: “What did we learn with the EUREC4A dataset?
A look at clouds and precipitation in the Tropics”
, curato dalla Dott.ssa Claudia Acquistapace. Il seminario si svolgerà sia in presenza presso la Lecture Room 1P – DICAM – Università of Trento, Via Mesiano 77 Trento, sia online al seguente link Zoom: (ID: 835 4359 4724, Passcode: 052914). Vi riportiamo un abstract del seminario e la biografia della dottoressa:

Almost three years ago, just before the pandemic, the EUREC4A field campaign was taking place, deploying a wide array of observational platforms in and over the tropical Atlantic Ocean around Barbados. The significant scope of the campaign was quantifying macrophysical properties of trade-wind cumuli as a function of the large-scale environment and providing a reference data set that may build a benchmark for the modeling and the satellite observation of shallow clouds and circulation. In addition to these big research questions, the observations allow for  investigating the trades' precipitation life cycle, including how precipitation  relates to evaporation and cold pools. Today, a special issue on  Earth System Science Data [1]  collects the datasets that have been produced, and more are still yet to come.  In this talk, we will go over the primary scientific outcomes from the EUREC4A campaign and discuss the latest research on mesoscale organization patterns as seen from satellites. We will also look at unique ship-based observations of clouds and rain. We will discuss how they interact with the ocean underneath and impact the atmospheric boundary layer humidity. Finally, we will discuss future challenges, still-open research questions, and opportunities for future studies.

Claudia’s path starts in Pisa, where she got her bachelor degree in general Physics, and then went on in Bologna, where she completed her master in physics focusing on atmosphere with a thesis on satellite remote sensing of light precipitation in Europe. Then, she moved to Cologne for completing a PhD within the Marie Curie initial training network focusing on drizzle detection but this time from the ground, using cloud radar Doppler spectra, for which she was awarded with the
Reinhard-Süring-Stiftung 2019 Research award. She employed her first post-doc to use her observations to evaluate the performance of the ICON-LEM model. She was then actively taking part in the EUREC4A measurement campaign as PI on the research vessel Maria S. Merian, conducting radar ship-based observations of clouds and rain in the tropics.
Currently she is completing a master in science communication at the University of Trento and she will soon start her new position as junior research group leader in Cologne, coming back to satellite remote sensing, this time for better understanding extreme precipitation events using machine learning methods.
She is the science communication manager of the PROBE Cost Action and she also got funding for outreach projects, like the videodocumentary on women in science “Wetoo: what they don’t tell you” [2] and for the realization of an outreach video on atmospheric boundary layer [3], which was awarded by the AISAM association with a communication price.

“Call for Abstract” per il Convegno GIT

La Società Geologica Italiana sta organizzando il “XVII Convegno Nazionale della Sezione GIT – Geosciences and Information Technologies”, che si svolgerà dall’11 al 13 settembre 2023 presso il Chiostro di Sant’Agostino, nel Comune di Pietrasanta (LU). Nelle giornate dell’11 e del 12 settembre, sono previste diverse sessioni scientifiche, tra cui una dedicata ad: “Analisi Dati nelle Geoscienze mediante l’applicazione di tecniche di Machine Learning”. E’ aperta, dunque, la “Call for Abstract” per tale sessione tematica e i testi dovranno essere inviati entro e non oltre il 18 giugno 2023.
