The NWC SAF provides the tools and the software that deliver tailored satellite information to support forecasting up to 12 hours ahead, known as Very Short Range Forecasting.
The general objective of the Nowcasting Satellite Application Facility (NWC-SAF) is to provide operational services to ensure the optimum use of meteorological satellite data in Nowcasting and Very Short Range Forecasting by targeted users. This is applicable to the MSG and the PPS satellite systems. To achieve this goal, the SAFNWC is responsible for the development and maintenance of appropriate SW Packages, as well as of all related tasks for user\'s support. Moreover, the SAFNWC intends to be a Centre of Excellence for Nowcasting in EUMETSAT.
SAFs are dedicated centres of excellence for processing satellite data, achieved by utilising specialist expertise from the Member States
SAFs are dedicated centres of excellence for processing satellite data, achieved by utilising specialist expertise from the Member States. SAFs generate and disseminate operational EUMETSAT products and services and are an integral part of the distributed EUMETSAT Application Ground Segment.
Each SAF is led by the National Meteorological Service (NMS) of a EUMETSAT Member State, in association with a consortium of EUMETSAT Member States and Cooperating States, government bodies and research institutes. The lead NMS is responsible for the management of each complete SAF project. The research, data and services provided by the SAFs complement the standard meteorological products delivered by EUMETSAT’s central facilities in Darmstadt, Germany.
Although may considered as the answer to all problems, satellite also come with some limitations. In this lecture one such limitation "Parallax Shift" is explained.
Although may considered as the answer to all problems, satellite also come with some limitations. In this lecture one such limitation, Parallax Shift is explained, and how you have to take this into account. Fortunately there are some solutions available to overcome this problem, which are also explained by Martin Setvak (CHMI).
Presentation on some of the typical convective scenarios with the focus on the usage of the background NWP fields and convective parameters in combination with satellite imagery.
Zoltan Polyanszky from the Hungarian Meteorological Institute, presents some of the typical convective scenarios with the focus on the usage of the background NWP fields and convective parameters. The role of the operational work of the forecaster who is responsible for issuing warnings is highlighted and concluding a reflection is discussed on what has been learned from the situations over the recent years.
Presentation during the event week on Convection in June 2011 by Helge Tuschy on the European Forecasting Experiment (ESTOFEX).
Presentation by Helge Tuschy from Deutscher Wetterdienst (DWD). He is one of the forecasters producing the valuable ESTOFEX forecasts and this lecture is on the basics of convection and how the convective outlooks in ESTOFEX are prepared.
Webcast on the influence of the the Black Sea on the initiation of convective storms in South Eastern Romania.
Presentation by Aurora Bell on the influence of the the Black Sea on the initiation of convective storms in South Eastern Romania. Several cases with Doppler radar and satellite images were presented in combination with other integrated data. The presentation was oriented towards forecasters and Aurora explained the role of the sea breeze in bringing together the right ingredients.
Nowcasting SAF presenting the new developments of cell tracking with SEVIRI satellite data in the SAF product, Rapid Developing Thunderstorm.
Presentation during the Convection Week 2011 by Jean-Marc Moisselin on the update to the Rapid Developing Thunderstorm (RDT) product of the NWC SAF.
The Physical Retrieval algorithm of NWC SAF retrieves the atmospheric temperature and moisture profiles as well as surface skin temperature.
The SEVIRI Physical Retrieval (SPhR) algorithm retrieves the atmospheric temperature and moisture profiles as well as surface skin temperature for one clear sky SEVIRI pixel, or a Field-Of-Regard (FOR) with contains M x M pixels. The central aim of the SPhR is to provide information on the water vapor contained in a vertical column of unit cross-section area in several layers in the troposphere and to provide some instability indices. These parameters are calculated from the retrieved profiles of temperature and humidity.
Vera Meyer discusses research on Cell tracking and Nowcasting using 3D lighting- and radar data in Southern Germany.
Vera Meyer (ZAMG) presents her PhD research on Cell tracking and Nowcasting using 3D lighting- and radar data in Southern Germany. Research conducted at DLR.
Presentation on the use of the MPEF Divergence Product for diagnosing the divergence associated with upper-level wind field disturbances that produces forcing for ascent and favours the development of deep moist convection.
Presentation by Christo Georgiev during the Event Week on Convection in June 2011. The presentation concentrates on the use of the MPEF Divergence Product for diagnosing the divergence associated with upper-level wind field disturbances that produces forcing for ascent and favours the development of deep moist convection.
Nefodina is an effective model designed to detect convective system evoluting in the Mediterranean basin.
Davide Melfi (CNMCA) presents the development on the NEFODINA product. This is an effective model designed for the detection and the forecasting of the convective systems evolution in the Mediterranean area. It is composed by a system of neural networks and a varying temperature threshold method. It is able to detect not only the convective clusters but also all the convective cells inside them. He explained the product and gave some examples of how the products are used.
Webcast on the detection and monitoring of convective storms by using MSG imagea and products.
Aydin Erturk (TSMS) present on the "Detection and Monitoring Convective Storms by Using MSG Image and Products". The MSG SEVIRI is crucial data source for the nowcasting applications. Storm top features with IR imagery were well defined and published. MSGView software being operationally used for detection and monitoring convective storms at Turkish State Meteorological Service. Two case studies (a cold U/V and a cold ring shape) were demonstrated and discussed in this presentation.
