Understand NWP outputs
Sofia Chabhi presents a marine forecast case study of Storm Ingrid.
The presentation examines the passage of Storm Ingrid (22–24 January 2026) and its severe impacts along the Moroccan coastline using satellite observations and remote sensing data. It analyzes the key oceanographic and meteorological features of the storm, highlighting how satellite imagery aids in monitoring extreme events and improving coastal vigilance.
Soukaina Boughanem talks about the process of forecasting and monitoring tropical convection over Morocco.
The presentation focuses on tropical convection over Morocco, with an emphasis on its forecasting and monitoring in relation to the northward extension of the ITCZ. The main atmospheric features and the use of numerical models, satellites, radar and observations for operational monitoring are also discussed.
Abhishek Lodh talks about how satellite observations, data assimilation and coupled numerical models improve forecasts of monsoons, tropical weather hazards and their impacts over the Indian subcontinent.
Accurate representation of initial conditions in NWP is critical for improving the prediction of high-impact tropical weather and monsoon systems over the Indian subcontinent. Operational developments at NCMRWF, including the assimilation of satellite-derived ASCAT soil moisture and INSAT-3D land surface temperature observations, demonstrate improved prediction of monsoon depressions, tropical cyclones, precipitation, and extreme temperatures, with enhanced forecast skill and extended predictive capability. These advances in land–atmosphere initialization strengthen operational early-warning information for weather-sensitive sectors and support better anticipation of impacts on communities, agriculture, infrastructure, and critical services.
Nanda Alfuadi talks about the multi-NWP model assessment regarding high-impact weather simulation.
The presentation examines the performance of four numerical weather prediction models (WRF assimilation, WRF non-assimilation, IFS, and GFS) during a heavy rainfall case in Jakarta, the capital city of Indonesia. Specifically, the discussion focuses on how effectively these models captured the high-impact weather signal starting three days before the event.
The NWC SAF MTG-I Lightning Imager Prototype Products Workshop introduces the upcoming NWC SAF GEO-LI software package, planned for release in 2027, and provides an overview of the new generation of products based on data from the MTG Lightning Imager.
The workshop combines technical presentations with practical examples, offering participants useful guidance on how to interpret and exploit LI-based products and their use in combination with other satellite products available in the NWC SAF EWC Viewer based on ADAGUC.
The recording of the event consists of three parts:

Case study about the extreme precipitation event in Rijeka, Croatia on 28 September 2022. The study focuses on the special case of convective development that caused the severe event.
This study accompanies the simulator.
The Nowcasting SAF is planning a new software package dedicated to the new geostationary MTG-S Infrared Sounder instrument (IRS). This new software package will generate Satellite Humidity And Instability products (sSHAI) that will be key in Nowcasting using the IRS instrument. It will also deliver services to make the best use of MTG-IRS channels and combine its virtues with those of the MTG imager FCI.
In this Workshop you will learn about these revolutionary product and services. You will also have a taste of what will come in a few months with MTG-IRS by using in real world applications the prototype product obtained from the polar orbiting IASI instrument.
The Workshop is comprised of 4 presentations:
Part 1. X. Calbet (AEMET) - Introduction GEO-S
Part 2. N. Peinado-Galán (AEMET) - sSHAI prototype
Part 3. N. Peinado-Galán (AEMET) and X. Calbet (AEMET) - Practical cases with course attendants using SHAI on the EWC
Part 4. Miguel-Ángel Martínez (AEMET) - Other services from the GEO-S package: quickIRS, sSHAI_ES and Remapping tool
Vinko Šoljan talks about forecasting and nowcasting of deep moist convection, satellite products used, NWP outputs and more.
In this presentation, we will demonstrate the process of forecasting deep moist convection (DMC) at Croatia Control and how satellite products are utilized in this process. This includes large-scale analysis and diagnosis using satellite data, as well as monitoring and nowcasting existing DMC using satellite products and radar data. In DMC forecast we primarily rely on the ingredients-based methodology and NWP guidance.
Georg Pistotnik covers the topic of drylines, shows it's relevance in severe weather development.
Drylines are boundaries separating warmer and drier from cooler and moister air, usually resulting from differential diurnal heating and therefore vertical mixing. The most common and distinct dryline in the Alpine region is the boundary between Foehn winds (dynamically driven) and upvalley/upslope circulations (thermally driven). Thunderstorms often form along drylines and intensify when they move onto their moist side, where CAPE and vertical wind shear are systematically enhanced and favor convective organization. This presentation highlights how station and readiosonde data, high-resolution satellite imagery and even webcam images can be integrated into the nowcasting of drylines and resulting thunderstorms, using some prominent cases of the past few years in the eastern Alpine region.

Liliane Hofer speaks about prognostic service of Austria, work organization, regional weather forecast specifics such as southerly föhn winds and others.
Various phenomena, some of which are regionally specific, such as southerly föhn winds or precipitation in northern or southern congestion, make the weather forecast in Austria very challenging at times. In addition, the topographically highly structured landscape also results in quite small-scale differences, for example in inversion weather conditions. All this and special customer products are highlighted in this presentation, as well as the basic working environment of the forecasters and, of course, the satellite products used for this purpose.

Katarina Katušić talks about Croatian Met Service work principles and schedules, case study and satellite products used during operational shift work.
The Weather and Marine Analysis and Forecasting Sector is a part of the Croatian Meteorological and Hydrological Service (DHMZ), and it is in charge of weather forecasts and warnings for the public and numerous companies. Over the years, we have gone through many challenges. Quite recently, during the lockdown, the earthquake severely damaged our headquarters, and even with those difficulties the work did not stop. We also prepare and present weather forecasts for national television. Furthermore, this presentation will cover the usage of weather satellite products in daily operational work.

Marco Stoll shows the importance of mountain waves in aviation forecasting.
Meteorological information is crucial for flight safety and efficiency. Mountain waves are an example of a potentially hazardous phenomenon for aviation that meteorological watch offices need to monitor and forecast. The typical appearance of the phenomenon in satellite imagery is illustrated, thereby making use of various MSG channels and RGB products. The difficult task of quantifying vertical speeds and estimating the degree of turbulence associated with breaking waves is discussed with the aid of NWP cross sections.
